If your parameters are not stable, this coral will not survive the first month. Corals do not die from wrong numbers. They die from unstable numbers. The difference between a thriving reef and a dying one is consistency, not perfection.

Stable mediocre parameters beat perfect parameters that swing. Every time.

What Exactly Is Coral?

Corals are animals. Not plants, not rocks. They belong to the phylum Cnidaria, which contains over 11,000 species including jellyfish, gorgonians, and anemones. More specifically, corals fall in the class Anthozoa, further divided into two subclasses that define the two main groups of aquarium coral:

• Octocorallia: Eight-tentacle corals including most soft corals (leather corals, gorgonians, star polyps)
• Hexacorallia: Six-tentacle corals including stony corals (SPS and LPS), zoanthids, and mushroom corals

All corals have specialized stinging cells called cnidocytes. These are the same cells that make jellyfish sting. In corals, they serve two purposes: capturing food from the water column and defending territory against neighboring corals. That territorial chemical warfare between coral types is something you need to plan around in a reef tank. Corals that grow toward each other will sting each other. Some of those stings cause irreversible tissue damage overnight.

Most photosynthetic corals have a symbiotic relationship with microscopic algae called zooxanthellae. These algae live inside the coral tissue and produce food through photosynthesis, sharing the energy with the coral. In exchange, the coral provides shelter and nutrients. When a coral is stressed by temperature swings, poor water quality, or insufficient lighting, it expels its zooxanthellae. The coral turns white. This is coral bleaching. Without zooxanthellae, the coral starves unless conditions improve quickly enough for it to reabsorb new algae. Many bleached corals do not recover.

The 6-Month Tank Maturity Rule

Before you add any coral to a new tank, the system needs to be biologically mature. That means a complete nitrogen cycle, stable parameters measured consistently over multiple weeks, established populations of beneficial bacteria, and ideally some natural pod and microfauna populations building up in the rockwork.

For soft corals and hardy LPS, 6 months is a reasonable minimum. For SPS, most experienced reefers recommend 12 months or more. This is not an arbitrary rule. SPS corals react instantly to parameter instability. New tanks cycle, swing, and settle. During that process, an SPS coral will die. Waiting until your tank is genuinely stable is the single most reliable way to improve coral survival rates.

The common mistake is treating coral addition as an early milestone. It’s not. It’s a late-stage decision in tank development.

Soft Corals: Start Here

Soft corals belong primarily to the Octocorallia subclass and are the most forgiving group for beginner reefers. They don’t build hard calcium carbonate skeletons. Instead, they have flexible, fleshy bodies supported in some species by tiny internal skeletal elements called sclerites. This makes them fast-growing, easy to propagate by fragging, and tolerant of the parameter swings that new tanks experience.

Lighting requirements are low to moderate. Most soft corals do well under T5 fluorescent, basic LED setups, or even modest PAR outputs around 50 to 150. Water flow should be moderate and indirect rather than direct blast flow. Most soft corals thrive in random, pulsing flow rather than laminar streams aimed at the coral.

One critical point about soft corals: they engage in allelopathy. They release chemical compounds into the water that can suppress the growth of nearby corals, particularly SPS. Running activated carbon helps manage this. If you want to eventually transition to a mixed reef or an SPS-dominant system, be strategic about how many and which soft corals you include. A tank full of xenia and leather corals will create a chemical environment that SPS struggle in.

The best beginner soft corals include:

• Zoanthids: Colorful, hardy, grow in colonies, propagate easily. Dozens of named morphs. Watch for palytoxin when cutting (wear gloves and eye protection)
• Mushroom corals (Discosoma, Rhodactis): Extremely tolerant of low light and moderate parameters. Some of the best beginner corals available
• Green star polyps: Fast-growing mat coral. Nearly impossible to kill once established. Can overgrow other corals, so give it its own rock island
• Toadstool leather coral (Sarcophyton): Hardy, substantial presence, and one of the easiest leathers to keep. Periodically sheds a waxy layer, which is normal
• Pulsing xenia: The coral that moves. Its rhythmic pulsing is one of the most distinctive visual features in the reef tank. Grows fast and can take over if not managed

LPS Corals: The Intermediate Layer

Large polyp stony (LPS) corals belong taxonomically to the Scleractinia order, the same as SPS, but their care requirements are significantly less demanding. Their large, fleshy polyps cover most of the underlying calcium carbonate skeleton, which gives them more visual presence and a different aesthetic than either soft corals or SPS. Many LPS are considered “meatier” corals that benefit from supplemental target feeding with mysis shrimp or coral-specific foods.

LPS corals require stable alkalinity and calcium for skeletal growth, moderate lighting (PAR of 100 to 250 for most species), and careful placement due to sweeper tentacles. Euphyllia species like torch, hammer, and frogspawn extend sweeper tentacles at night that can sting and damage neighboring corals. Give LPS adequate spacing, at least 4 to 6 inches from neighboring corals, and watch for nighttime expansion when placing them.

Euphyllia species also exhibit cross-compatibility. Hammer and frogspawn are actually the same species (Euphyllia ancora and Euphyllia paradivisa) and can be placed closer together than either can to torch corals (Euphyllia glabrescens). Mixing torch corals with other Euphyllia types results in stinging and tissue recession. This is one of those placement details that most beginners learn after losing a coral to it.

Popular beginner-to-intermediate LPS corals include:

• Hammer coral (Euphyllia ancora): Hammer-shaped fleshy tips, moderate requirements, stunning movement in flow
• Torch coral (Euphyllia glabrescens): Long, waving tentacles, one of the most sought-after LPS. Keep separate from other Euphyllia
• Duncan coral (Duncanopsammia axifuga): One of the easiest LPS, fast-growing, tolerates moderate flow and lower light
• Blastomussa coral: Small, compact polyps, tolerates lower flow and light, excellent beginner LPS
• Brain corals (Favites, Favia, Platygyra): Encrusting growth form, moderate requirements, steady growth in a mature system

SPS Corals: Advanced Territory

Small polyp stony (SPS) corals are the most demanding category in the reef hobby. They require the highest water quality, the most stable parameters, the strongest lighting, and the most flow. In exchange, they provide the most dramatic long-term visual transformation of any coral category. A mature SPS reef is genuinely one of the most impressive things you can build in this hobby.

The primary parameter targets for SPS-dominant systems are tight: alkalinity 8 to 9.5 dKH with minimal swing, calcium 400 to 450 ppm, magnesium 1250 to 1350 ppm, nitrate below 5 ppm (some successful SPS reefs run near zero), phosphate 0.03 to 0.08 ppm. The exact numbers matter less than the stability of those numbers. A daily swing in alkalinity from 7 to 10 dKH will cause SPS tissue recession faster than a sustained alkalinity of 7.5 dKH will. Stability is the priority.

SPS corals also need high PAR. Most branching species like Acropora and Pocillopora want 250 to 400+ PAR. Encrusting species like Montipora can do well at lower PAR values around 100 to 200. Lighting equipment for a serious SPS tank is a real investment. T5 hybrid setups and high-output LED systems from established brands are the standard. Budget LED fixtures that don’t hit adequate PAR are one of the most common causes of SPS failure.

Genuinely beginner-friendly SPS species include:

• Montipora capricornis: Plating encrusting growth, more forgiving than most SPS, good entry point for first SPS attempt in a mature tank
• Seriatopora hystrix (birdsnest coral): Thin branching, fast-growing, more tolerant of moderate parameters than Acropora
• Stylophora pistillata: Compact branching, hardy for SPS, good indicator species for overall tank health

Acropora is the pinnacle of SPS reefing and genuinely belongs in a system with at least 12 months of stable operation, established dosing or calcium reactor, and a keeper who tests parameters at least twice a week. Don’t start there.

NPS Corals: The Niche Category

Nonphotosynthetic (NPS) corals do not contain zooxanthellae. They cannot produce food from light. They survive entirely by capturing food from the water column, which in nature means a constant supply of planktonic organisms flowing over them. In a home aquarium, that means you need to provide target feedings multiple times per day.

The sun coral (Tubastraea species) is the most commonly available NPS coral and the least difficult in this category. Its brilliant orange or yellow polyps only fully extend when food is present, which is one of the more spectacular feeding displays in the reef hobby. Training a sun coral to open for feedings requires consistent food introduction at the same time daily. Most keepers use a small container or dome to isolate the coral during feeding so food doesn’t disperse through the tank.

Other NPS species like carnation coral (Dendronephthya) and chili coral are significantly harder. Carnation coral has one of the lowest survival rates of any coral sold in the hobby. It requires near-constant feeding of specific particle sizes and extremely stable parameters. It is beautiful. It’s also almost always dead within 3 to 6 months in anything but an expert-level dedicated NPS system. Do not buy carnation coral unless you have specifically built a system around it.

Coral Chemical Warfare and Placement

Corals compete for space on natural reefs and they bring those competitive strategies into your tank. There are two main ways corals fight each other: physical contact through sweeper tentacles and nematocysts, and chemical allelopathy through compounds released into the water.

Physical contact aggression is the more obvious of the two. Torch corals extend sweeper tentacles that can reach 6 inches (15 cm) or more at night. Brain corals extend mesenterial filaments that digest tissue on contact. Favia and Favites corals send out digitative mesenterial filaments that can sweep several inches beyond their visible skeleton. Any coral within range of these weapons will show tissue recession at the contact point.

Chemical allelopathy is less visible but often more damaging over the long term. Leather corals and some soft corals release terpenoids and other compounds that suppress the immune response and growth of nearby corals, particularly SPS. This is why full SPS tanks often avoid leather corals entirely, or run only small quantities with heavy skimming and activated carbon to pull the chemicals out of the water column. Activated carbon replacement every 4 to 6 weeks is standard practice in mixed reefs for this reason.

Placement principles to follow:

• Place LPS away from other corals by at least 4 to 6 inches (10 to 15 cm) accounting for maximum tentacle extension at night
• Keep Euphyllia species separated by type: hammer/frogspawn can be near each other, but keep torch separated
• Soft corals should not be directly adjacent to SPS frags or colonies
• Place SPS high and toward the flow for the PAR and circulation they need
• Place LPS mid-tank with moderate, indirect flow
• Place soft corals and mushrooms lower in the tank where flow and PAR are reduced

Fragging Culture

Fragging is the practice of cutting a coral into smaller pieces, called frags, for trading, selling, or expanding a colony in the same tank. It’s one of the foundational practices of the reef hobby and a primary driver of how hobbyists build their coral collections affordably.

Most soft corals can be fragged with simple scissors or a razor blade. LPS corals require a band saw or similar cutting tool to section the calcium carbonate skeleton. SPS corals are fragged with coral cutting tools or small bolt cutters that snap branches cleanly. All fragging should be done with clean tools, protective gloves (especially for zoanthids, which contain palytoxin), and the frag immediately attached to a frag plug with reef-safe gel glue.

The local reef club or online reef community frag swap is one of the best ways to build a diverse coral collection. Frags from established home reef systems are often healthier than store-bought wild-caught specimens because they’re already adapted to captive conditions. Buying from other hobbyists also gives you the lineage and care history of the coral, which store-bought specimens rarely provide.

Wild-Caught vs. Maricultured vs. Aquacultured

Where your coral comes from affects its health, its acclimation success, and the environmental impact of your purchase.

Wild-caught corals are collected directly from natural reef ecosystems. They carry parasites, hitchhikers, and the stress of long shipping. They require thorough quarantine and careful acclimation. They’re more expensive than alternatives and carry the highest environmental impact. Wild-caught is rarely the best choice when alternatives exist.

Maricultured corals are grown on ocean-based coral farms in their natural environment, then harvested. They’re more sustainable than wild collection and support local reef economies. The acclimation challenge is still present because they transition from natural conditions to a home aquarium. Expect some adjustment period and quarantine.

Aquacultured corals are the best option for most hobbyists. They’re grown entirely in captivity, fully adapted to aquarium conditions, free of wild reef parasites, competitively priced due to scalable production, and carry no wild collection environmental impact. Aquacultured frags from domestic facilities are the default recommendation for any beginner or intermediate reefer.

FAQs

Closing Thoughts

Coral reefing is a long game. The hobbyists who succeed are the ones who let their tank develop, learn the chemistry, start with appropriate corals for their system’s age, and resist the urge to push into SPS before the tank is ready. The ones who fail are usually the ones who stock too early, choose corals that don’t match their system, or underestimate how much parameter stability matters.

Start with soft corals. Master stability. Move to LPS when your parameters are genuinely consistent over months. Consider SPS when your tank has been running well for over a year and you’re ready for the equipment investment and the tighter management it requires. There’s a thriving reef at every level of this progression. You don’t have to rush to the next category to enjoy the hobby.

For quality aquacultured coral frags and reef supplies, check Flip Aquatics and Dan’s Fish. Both prioritize tank-raised and aquacultured specimens and are reliable sources for corals that are adapted to captive conditions.

Origins And Habitat

The wide majority of Acropora corals originate from the Indo-Pacific in major reef systems like the Great Barrier Reef off the coast of Australia.

With approximately 150 known species within the genus Acropora, only three occur outside of those regions far away in the Caribbean¹. These species are the staghorn coral (Acropora cervicornis), elkhorn coral (Acropora palmata), and fused staghorn coral (Acropora prolifera).

All three Caribbean species play a major role in the reef ecosystem. They provide shelter for juvenile fish and invertebrates and house a plethora of microscopic life.

Similarly, Acropora from the Indo-Pacific are also responsible for creating the calcium carbonate backbone of many reef ecosystems. They grow at the tops of reefs where sunlight is abundant. Their hard skeletons have adapted to withstand the constant push and pull of the waves above.

However, these stony corals have not adapted to the destruction caused by fishing trawlers, ship anchors, or the effects of climate change. Acropora have sadly become the face of dying reefs with lifeless white branches and deserted marine structures.

What Do They Look Like?

Acropora are very easy to tell apart from most other corals, but can easily be confused with other small polyp stony (SPS) corals. Given that there are many natural species of Acropora as well as modified varieties from the aquarium hobby, it is difficult to know exactly what you’re looking at. In general, it’s best to know the appearance of Acropora and then narrow them down from there.

It should also be mentioned that the appearance of any given Acropora can vary greatly depending on the conditions under which they’re being kept; these differences is in coloration and extension as well as subsequent movement and growth of the coral.

Acropora–and many other SPS species–are referred to as ‘sticks’. This is not a misnomer as these corals really do look like a series of intertwined branches, even more so when you receive a single branch as a frag.

These corals are seen in branching forms in the wild as well, forming tight acropora colonies with relatively thick branches. Other times, these branches is very skinny and spread far apart and even come in plating varieties. In the more ornamental species, the flesh is often a bright color while the polyps are highly contrasting.

Each polyp has its own tube called a radial corallite which can create a bumpy appearance; the polyps are very long, which can also create a fuzzy texture. An axial corallite is located at the end of each branch and appears to have a hole in the center. These corallites are used to distinguish different species of Acropora coral from one another.

Acropora Coral Care Guide

Acropora need to be placed where light and water flow allows. This is at the top and middle portions of the reef, though some extremely high-tech setups may allow for lower portions to be utilized.

As we will discuss, these corals need plenty of room to grow and will fight each other when placed too closely together. That, and they can also grow into very impressive structures as well!

Temperament

Though Acropora might seem harmless as they don’t have any apparent sweeper tentacles, they are actually very aggressive. These stony corals are determined to preserve their spot on the reef and will eagerly damage other nearby coral species.

Some hobbyists frag their corals to prevent this from happening while others allow them to adapt and change paths. One thing is for sure though, good placement in the first place will prevent many future problems down the line.

Maintenance

Acropora corals are difficult to keep. But just how difficult are they?

Needless to say, even the most experienced hobbyists have difficulty cultivating a healthy and sustaining SPS system. There are a few reasons why they’re so challenging, though. This mainly comes down to the type of lighting, the intensity of lighting, and the spectrum of lighting as well as the direction and intensity of water flow.

In addition, nutrients and water quality play a huge role in the color and growth of Acropora, though their needs are relatively straightforward on paper; it is almost necessary to have an automated dosing system or calcium reactor when dealing with large numbers and colonies of Acropora to ensure stability.

There are two things that might happen to an unhappy Acropora: 1) the coral changes colors, otherwise known as ‘browning out’, or 2) the coral dies over the course of a few days or weeks regardless.

One of the biggest achievements of having an SPS system is having a display of colors. Though some aquarists might have great coral growth, lacking color is enough for disappointment.

This challenge, and the large payoff for displaying intricate reef structures and bold colors, make Acropora the holy grail that keeps hobbyists coming back.

Lighting

In nature, Acropora are found at the very top of the reef. The aquarium hobby has made it possible to keep them from the middle and up, though a large amount of light is needed.

The conundrum with SPS corals is that the more they grow, the more they shade out the lower branches of themselves. This, in addition to them being light-loving already, can make having a large colony for a long time very difficult.

SPS corals are especially susceptible to browning out when they don’t receive enough light and bleaching when they receive too much and/or are moved between environments too quickly. The perfect colorations will be reached through trial and error of different lighting fixtures, intensities, and spectrums.

At the very least, most Acropora species need at least 200 PAR. However, they don’t start thriving until placed under 300-500 PAR, with some systems successfully running above 600 PAR. That is a ton of light that your coral needs to adapt to over time.

Over the past few decades, hobbyists have argued about which light fixtures are best for Acropora. There is no clear consensus and success has been found under each type, whether it be LEDs, T5 fluorescents, or metal halides. My personal opinion, is try a hybrid system like the Aquatic Life system.

Water Flow

As with any coral, water flow is needed to deliver nutrients to corals while also removing waste and preventing algae and other microorganisms from settling. As mentioned before, these corals live on the top of reefs where water flow is naturally high due to wave activity.

Not only do Acropora need high water flow but they also need random water flow. Random water flow from an aquarium wavemaker will ensure that the coral grows naturally; higher flow can result in thicker branches while lower flow will cause the coral to expand as much as possible.

As the coral grows, the overall flow throughout the colony will naturally decrease. This can cut off nutrient exchange from the densest areas of the colony and even start to impede delivery to nearby colonies.

The answer to this is simple: add more flow or frag the colony to increase water movement once again. Always keep an eye on how efficiently water is circulating throughout the system to maintain steady growth.

Water Parameters

SPS water parameters are somewhat of an oxymoron. These corals love clean water but need high, stable levels of nutrients for growth. This makes it very difficult to regulate in a home aquarium setting, though modern technology through automatic dosers and smartphone applications has made balancing nutrients that much easier.

There are a few parameters that you need to keep a careful eye on like alkalinity, calcium, magnesium, nitrate, and phosphate.

Alkalinity, calcium, and magnesium all work together to facilitate the growth and color of Acropora. They are introduced into the system through natural seawater or through marine salt mix or other supplements; as we’ll discuss later, these parameters are the most commonly dosed once coral growth becomes exponential.

On the other hand, nitrate and phosphate is introduced into the reef aquarium through waste from fish, invertebrates, and bacteria. These parameters need to be low, but available., reef tanks run under 40 ppm nitrate and under.01 ppm phosphate. An imbalance of these parameters can lead to algae and poor coral growth.

For reefers who achieve this level in the hobby, the usual issue is lack of nutrients, due to the high end nature of their equipment. Dosing nitrates and phosphates are not uncommon!

Dosing

As corals grow, they take up nutrients. For average aquarists, these nutrients are reintroduced into the system by way of water changes, fish waste, and other natural processes in the aquarium. However, once Acropora start to grow, they can start to have high demands.

More specifically, you will need to balance alkalinity, calcium, and magnesium. These three parameters work together to create stability. Perform regular tests to observe which and how nutrients are being used throughout the system and add as needed. It will take time and testing to find which product combinations work best for your system.

For alkalinity, calcium, and magnesium especially, it is imperative to change parameters slowly. This is done over the course of weeks and months. However, once the deficit is realized, dosing is done weekly or as needed by a scheduled application or machine. There are also auto tools like the Neptune Trident that can automate dosing entirely. A trident is something to consider if you are considering designer Acropora corals.

Sometimes, home aquarium systems is too clean. In this case, phosphate and/or nitrate might need to be dosed. Though this will be fixed by feeding more heavily or even introducing new livestock into the tank.

Feeding

For the most part, Acropora corals get the food they need through their symbiotic relationship with photosynthetic dinoflagellates called zooxanthellae.

These stony corals do not respond well to target feeding. Most times, they will retract their polyps and start to excrete slime and filaments to protect themselves. On the other hand, they have successfully been broadcast fed a variety of dedicated coral foods as well as zooplankton and small organisms.

Some hobbyists like to give their SPS corals amino acids. These supplements chemically help with protein production which can lead to increased growth and more vibrant colors.

It should be noted that it can take quite a while for some Acropora to settle in. They will likely turn brown over the first few weeks and months of introducing them into your aquarium. But they will quickly establish themselves and start to grow once stability has been reached.

What Are Good Tankmates?

Acropora corals is kept with all reef-safe species. In fact, Acropora do best when they receive natural nutrients from fish waste.

As these corals can grow very large and need intricate reef tank setups, most aquarists have as much space as they need to house a variety of fish species. Some of these options include tangs which can also be beneficial for picking away any algae that might start at the base and lower portions of the colonies.

It should be noted that some fish, like butterflyfish (Chaetodontidae family), are largely regarded as being not reef-safe. That being said, many hobbyists have found that they aren’t as likely to pick at SPS coral as they are at LPS or soft corals. Still, always use caution when adding a possibly not reef-safe species.

Fragging

Fragging Acropora is profitable and is necessary over time as your corals start to grow. Fragging these corals is not difficult, though it is intimidating to work with a very expensive or sensitive species. If you’ve ever fragged any other kind of branching SPS coral before, the method is the same.

For a clean cut, an electric saw is recommended. Otherwise, you may use a bone cutter. Simply cut the piece of Acropora where desired and use a coral dip or iodine for better recovery. For the bone cutter method, see the video from C&M Aquatics below for a visual.

If selling these frags, you may want to pick the more desirable tips from the colony and not just a straight stick. It is also important to take from a place on the coral where the natural contour of the colony isn’t lost or impeded.

Sometimes you might find that you’ve accidentally knocked off a piece from one of your colonies while doing maintenance in the tank. Simply stick this piece on a piece of rock or attach it to a frag plug. Chances are that it will make a full recovery and start forming its own colony!

Why is yours turning white?

, your Acropora is turning white because it is not happy. Bleaching is when the coral expels the symbiotic zooxanthellae from its calcium carbonate skeleton, leaving the colony stripped of color. This is in response to unfavorable conditions or sudden changes in water chemistry.

For most hobbyists, it will be very easy to tell where the mistake was, especially if other corals in the tank bleached too. However, sometimes these things are untraceable and seemingly have no rhyme or reason. Once the coral has fully bleached, there is little to no chance that it will recover and algae will quickly cover the white remnants.

If only one area of the coral has started to bleach then there is some hope, though recovery will be difficult. All in all, the most important aspect of a reef tank is stability. The problem is that you need stability while also addressing the problem, which might require gradually changing parameters.

This needs to be a slow and steady process. The coral can absolutely recover, but it will take a few months.

If your coral isn’t experiencing bleaching but still losing flesh, then there is a deeper underlying problem like disease, infection, or pests.

Slow & Rapid Tissue Necrosis (STN & RTN)

Both slow tissue necrosis (STN) and rapid tissue necrosis (RTN) are somewhat of a mystery in the aquarium hobby. These conditions cause the coral to lose its flesh gradually or all at once with no apparent reason; this can happen overnight to an aquarium that has successfully been running for years.

Right now, it is believed that these conditions are caused by an unknown organism that causes an unfavorable reaction due to changes in environmental conditions. There is no known cure for STN or RTN either, though recovery attempts is made through quickly fragging the coral or dipping the coral in an iodine solution.

Flatworms

Many SPS corals have their own designated pest invertebrate and Acropora corals are no different. These flatworms are very difficult to see but is reflected by the overall loss of color in the coral. Small missing pieces of flesh on the coral will also gradually spread across the colony, indicating where the flatworm has eaten.

Luckily, there are a few products available to treat Acropora-eating flatworms, though these treatments are aggressive and will need regular water changes to ensure that other corals stay safe. There are a few livestock options for pest control too, like Halichoeres species of wrasse along with leopard wrasses (Macropharyngodon meleagris), though this is not guaranteed.

Acropora-eating flatworms is very difficult to diagnose and even more difficult to treat. It is possible, though.

Where To Purchase

Acropora Corals is purchased from either local fish stores or online reef shops. When search for Acroporas, the reputation of the seller is critical and you should only work with a what you see is what you get (WYSIWYG) coral seller if looking online.

Acroporas are designer corals these days. There are many Acros with their own brand names now that are associated with the coral seller or store. Many fetch for high prices. Be prepared to shop around and look to be selective if you are start looking for designer corals.

Closing Thoughts

Acropora are the end goal for many hobbyists: they have incredible colors and grow into immense structures. Sadly, the rumors are true and these corals are the most difficult to keep due to their need for high lighting, high water circulation, and stable water parameters.

Still, they remain a trademark for the picturesque home reef aquarium.

What It Is Actually Like Growing Montipora Coral Care to A Complete Guide

Coral growth is measured in weeks and months, not days. You will stare at your frag daily and see nothing. Then one morning, you notice new polyp extension or a visible encrustation line. That moment is deeply satisfying.

Corals open and close based on lighting and flow. Learning to read your coral’s polyp extension tells you more about tank conditions than any parameter test.

Nuisance algae will grow on and around your coral. Keeping it clean without damaging the tissue takes a gentle hand and a turkey baster. This is a regular maintenance task.

The color payoff is real. A coral that looked brown in the store develops vivid greens, purples, or oranges under proper lighting over weeks. That transformation is what makes reef keeping addictive.

The Montipora Coral Care to A Complete Guide is a go-to recommendation for newer reefers, but it is not bulletproof. Lighting, flow, and placement mistakes kill more frags than disease ever will. After maintaining reef tanks for over two decades, I know exactly where people go wrong with this coral.

More coral frags die from too much light than too little. That surprises most beginners.

Corals grow slowly and demand stable conditions for months and years. This is a long-term commitment to water chemistry, lighting schedules, and consistent maintenance.

Coral keeping is gardening with saltwater. The patience required is identical.

Do you want to know all about Montipora coral care? If so, this blog post is for you! We cover all the basics in order to keep your corals happy and healthy. There are many different types of Montipora that exist today; however, they all require the same basic care. We’ll cover everything from lighting requirements, parameters, and placement. Don’t worry, it’s easy as 1-2-3! Let’s dive in!

What Most Care Guides Get Wrong About Montipora Coral Care. A

Want easy, fast-growing coral? Start with green star polyps or zoanthids. Want a challenge? Get SPS and invest in dosing equipment.

Many care guides make the montipora coral care. A sound easier than it really is. They’ll list basic parameters and call it a day. In my experience running reef systems, stability matters far more than hitting a perfect number. Flow and placement get glossed over constantly. I’ve seen perfectly healthy montipora coral care. A colonies stress and close up simply because they were in the wrong spot. Getting flow right is half the battle. The other mistake is overfeeding or over-supplementing. More is not better with corals. Clean water and patience will outperform any additive regimen.

The Reality of Keeping Montipora Coral Care to A Complete Guide

Lighting is the most common source of coral death. New reefers blast their corals with too much PAR on day one. Corals need to acclimate to your lighting over weeks. Starting at 50% intensity and slowly ramping up prevents bleaching and tissue recession.

Flow matters as much as light. Dead spots collect detritus on coral tissue and cause tissue necrosis. Too much direct flow strips flesh from the skeleton. Finding the right flow pattern takes observation and adjustment.

Stability beats perfection. A reef tank with slightly elevated nitrates that stays consistent will grow coral better than a tank with perfect numbers that swings every few days. Corals adapt to stable conditions. They die from instability.

Biggest Mistake New Owners Make

Placing a new coral frag in the highest-light spot of the tank immediately. Corals from a store or vendor have been in shipping bags for hours. They need low light and gradual acclimation. Blasting them with full intensity causes bleaching within days.

Expert Take

Start your lights at 50% and increase by 10% every two weeks. More corals die from too much light too fast than from any disease I have encountered in 25 years of reef keeping.

Frequently Asked Questions

Is Montipora coral good for beginners?

Montipora is one of the easier SPS corals to keep and is often recommended as a gateway into SPS keeping. While it still requires stable water parameters, strong lighting, and good flow, it is more forgiving than Acropora and other demanding SPS species.

How fast does Montipora coral grow?

Montipora is one of the fastest-growing SPS corals. Under ideal conditions with proper lighting, flow, and supplementation, plating varieties can grow several inches per year. Encrusting forms spread gradually across rockwork. Growth rate depends heavily on calcium, alkalinity, and magnesium stability.

Why is my Montipora turning white?

White patches on Montipora indicate bleaching from excessive light, rapid parameter swings, or elevated temperatures. STN (slow tissue necrosis) appears as white areas at the base that slowly spread. Check your parameters, reduce lighting intensity if needed, and dip the coral if pests are suspected.

What lighting does Montipora need?

Montipora thrives under moderate to high PAR lighting, between 200 to 350 PAR. LED fixtures, T5 fluorescents, and metal halides all work well. Plating Montiporas is placed in the middle zone of the tank, while encrusting varieties do well on rockwork at various heights.

Can Montipora and Acropora be kept together?

Yes, Montipora and Acropora can coexist in the same tank since they have similar requirements for light, flow, and water chemistry. However, be aware that Montipora grows faster and can shade or overgrow slower-growing corals if not maintained with regular fragging.

Origins And Habitat

Species of Montipora coral is found at all depths of the reef. They are largely found throughout the Indian and Pacific Oceans, with most specimens within the aquarium hobby originating from waters around Australia and Indonesia.

These corals are a type of small polyp stony (SPS) coral, which means that they excrete a hard calcium carbonate skeleton that houses photosynthetic zooxanthellae. SPS corals, such as Montipora, are the foundation for coral reefs as they build hard structures that shelter a plethora of life; they have evolved to be able to withstand turbid waters where other soft corals and large polyp stony (LPS) corals would be damaged by strong waves and currents.

SPS corals also thrive in intense light. Some of the most notable species, like those from the Acropora coral genus, is found at the top of the water column under direct sunlight. Montipora corals are not as demanding when it comes to lighting, but they will still thrive in areas with lots of light available.

Plating varieties that grow outwards from the reef will also choke out any other corals that might fall in the shadow below them.

Is This Hard To Keep In The Aquarium?

In regards to SPS, Montipora is one of the easiest species you can keep in the aquarium. That isn’t to say that they is kept by anyone, though.

Montipora corals need high lighting, high water flow, and stable water parameters. Though this might sound reasonable for beginners, many hobbyists aren’t at that point with their tanks yet. At the very least, an aquarium should be one year old before attempting to add any SPS. This will allow time for the tank to settle, for algae outbreaks to end, and to develop a true understanding of how this mini-ecosystem works.

However, if you have successfully kept soft corals and LPS and have seen growth and stability, then you may be ready to try SPS corals. On top of being easy to keep, Montipora coral is a popular entryway SPS species due to the many different varieties, shapes, and colors it’s available in.

Montipora can come in branching, plating, and encrusting coral varieties in almost all colors. Alongside with birdnest corals, the montipora is a good stepping stone into advanced SPS species like Acropora corals.

What Does Montipora Coral Look Like?

Montipora is somewhat challenging to identify since it can come in so many varieties and be categorized under many designer names. In general, it’s best to know the general attributes of each type of Montipora coral variety regardless of the color or common name given.

Branching

The most popular branching species of Montipora coral is Montipora digitata. From there, the most common colors of Montipora digitata are orange (‘Forest Fire Montipora digitata’) and green (‘Green Montipora digitata’).

Like other branching SPS corals, branching Montipora grows into fascinating, complex structures. These corals have thicker branches with antler-like tips. The polyps are very concentrated and can create a very fuzzy appearance. A healthy branching Montipora will have white tips that indicate new growth.

Though these corals will grow towards the light on their own, new growth will start to shade out any old branches below. Because of this, it’s often necessary to regularly frag and trim the colony for optimal health.

Plating

Plating Montipora is probably the most popular variety of this particular coral species and definitely one of the easiest to recognize. Most specimens of plating Montipora coral belong to Montipora capricornis, though true identification is difficult.

These corals are aptly named after their mostly horizontal circular growth. Plating Montipora corals have a rough texture with polyps that do not extend very far. These corals will continue to expand outwards as far as they can, but will eventually start to plate upwards as well.

Though plating Montipora coral brings another dimension to the reef aquarium, a colony can take up a lot of space. Due to its outwards growth, it eventually shades out anything that grows below it. This can take a lot of real estate from the rest of the reef; because of this, many hobbyists try to place them as low as lighting allows.

Encrusting

Encrusting Montipora corals aren’t as popular as branching or plating varieties, but they’re still a good choice for bringing some additional color into the reef aquarium. Most encrusting corals will belong to Montipora verrucosa, though this is not always true.

This coral has a very hard and bumpy appearance; the individual polyps are barely noticeable. They do not come in as many color options as the previous varieties of Montipora coral and are mostly limited to orange, green, and purple.

Encrusting Montipora quickly grows over rock and other structures in the aquarium. Though they are not the most obvious coral in the aquarium, they can bring unique color and texture.

Placement In The Reef Aquarium

In general, all varieties of Montipora coral is placed in the middle or top of the tank. They need moderate to high light and moderate to high water flow. Based on the setup of the aquarium, this could even allow Montipora to be grown farther down towards the substrate.

The most important factors about placing Montipora coral are adequate and even water flow, especially with branching varieties. Branching Montipora can quickly create a dense cluster of coral which can lessen water flow. This means that nutrients and gas exchange lessen, which can start to affect the overall health of the coral over time.

This is solved by adding more water flow or fragging the corals to increase water circulation once again. In general, it is also best to have random water flow throughout the tank rather than unidirectional water flow to keep debris from piling up in one spot. This is achieved with multiple pumps or ones that have a randomized setting.

Do they Need High Light?

Yes, Montipora needs high light. As one of the least light-demanding species of SPS, they still need at least 150 PAR with appropriate frequencies and intensities.

Like other corals, Montipora is acclimated to higher portions of the tank over time and many have successfully been kept at areas receiving 200-300+ PAR. If they are not receiving enough light, they will start to lose their color and may even turn brown; if they are receiving too much light, they will start to bleach.

A brown Montipora is a sure sign that the coral is not receiving enough light, though this could also be due to other stressors as well. Shadowing is also a problem with SPS corals as they get larger. This is more pronounced when using LED lighting. It’s best to work with a high end LED light like an EcoTech Radion. Or consider a hybrid system when working with a heavily stocked SPS tank.

How Do You Place Encrusting?

Though branching and plating Montipora corals don’t need much special consideration in regards to placement, many hobbyists choose to keep their encrusting species on rock islands.

While SPS growth isn’t fast at first, it can start to become exponential in a very short period of time. This is especially true with encrusting Montipora that will shamelessly grow over anything that it can, including pest algae and other corals.

In order to control the spread, many hobbyists dedicate a certain area of the tank just to encrusting Montipora. It is also a popular option to allow it to grow up the wall of the aquarium, though many hobbyists prefer a green star polyp (Pachyclavularia violacea) backdrop instead.

Temperament In The Aquarium

One of the best things about Montipora coral is that they are almost completely harmless to other corals. These corals have barely any sting and will not hurt other corals they come into contact with. However, this is not true if they come in contact with other corals.

SPS are delicate animals. They do not have much ability to sting and will bleach if you look at them the wrong way. Because of this, it is crucial to keep more aggressive corals far away from SPS colonies.

LPS with long sweeper tentacles are especially to blame as they can quickly hit a branch of SPS and cause injury. Though most Montipora are able to recover from injury, there is time for infection and algae to grow which can negatively impact the overall health of the coral.

If attempting a mixed reef, make sure that there are distinct zones of aggression, allowing plenty of space for sweeper tentacles and potential growth.

Care And Maintenance

Montipora coral does not require a lot of maintenance. If an aquarium is stable, it is most important to keep that stability. When dealing with SPS, that mostly means maintaining water parameters through dosing.

Because SPS corals build calcium carbonate skeletons, they need a good supply of nutrients, including trace elements and alkalinity and calcium supplementation (like E.S.V). Since Montipora coral is a faster-than-average growing coral, dosing might also be necessary to keep up with growth even if the colony isn’t large and if there aren’t many other SPS in the aquarium.

Each system will be different and dosing frequencies and amounts can only be determined by recording and documenting how nutrients are used throughout the tank. It should also be noted that some species of Montipora are much more forgiving of instability and less-than-optimal conditions than others.

Dosing

The main parameters you need to dose for successful Montipora coral growth are alkalinity, calcium, magnesium, and trace elements. It is necessary to analyze how these levels change with and in between water changes to determine how much dosing is necessary.

As new water is circulated throughout the aquarium, nutrients are used for skeletal growth. This depletes nutrients, which can only be added through new water or through dosing; in order to minimalize maintenance and to increase daily stability, it is simpler and more effective to dose.

Because of this need to dose, many hobbyists equip an auto-doser to their system. These is costly at first, but they will add the exact amount of product needed to maintain ideal levels and eliminate the need for additional upkeep.

If you are running a very clean system in regards to nutrients, then it might also be necessary to dose nitrates and phosphates–though, most reefers are trying to bring these two parameters down instead of increasing them.

Feeding

It might seem counterintuitive to feed SPS as they lack fleshy polyps that will quickly accept foods, but SPS actually appreciate broadcast feedings every now and then; target feeding is not recommended and can actually cause the coral to retract.

Most of the food your coral needs will be given through the photosynthesis processed by symbiotic zooxanthellae. However, you may supplement feedings with amino acids and zooplankton.

Chemically, amino acids are the backbone of proteins. Increased proteins mean increased growth, which can improve the size, color, and overall health of the coral. On the other hand, zooplankton is processed as regular food.

As Montipora coral gets most of its ‘nutrition’ from lighting, amino acid and zooplankton supplements are not regularly needed and should not be overdone; some systems that run higher nutrients don’t need them at all. In low nutrient systems, supplemental feedings should be done one to two times a week at the most.

Again, the schedule will depend on how your system responds.

What Are Good Tankmates?

Montipora coral is kept with all reef-safe species. SPS is easily picked at by more advantageous species, like marine angelfish and butterflyfish, so it is best to go with those that are guaranteed to be safe, like:

• Damselfish
• Tangs
• Wrasses
• Anthias
• Cardinalfish

It is not impossible to keep certain species of butterflyfish with SPS, like the copperband butterfly (Chelmon rostratus), though this will largely depend on the personality of the individual fish.

It should also be noted that plating Montipora coral can easily be irritated by wandering snails and crabs. Though they shouldn’t cause too much damage, you might want to avoid hermit crabs and larger snails that will unknowingly scrape the top of your Montipora.

Fragging

Fragging Montipora coral is easy (video source), especially plating varieties. In some ways, fragging SPS is easier than fragging LPS or soft corals, though the recovery rates is a little trickier.

In order to frag plating Montipora, simply break the plate up. This is done inside or outside of the tank as long as you have full control over where the break is. A bone cutter can also be used to make smaller, more precise incisions.

In order to frag branching or encrusting varieties, you will need a bone cutter to split a branch or to get an encrusted piece off the rock. Once done, simply glue the frag to a frag plug or back to a piece of rock in the aquarium.

A coral dip, like iodine, is recommended to help speed up recovery, though this step is not entirely necessary.

Pests

Even though Montipora are some of the easiest SPS to keep, they come with some unique challenges. One of these challenges is that they’re one of the most susceptible corals to bring unwanted pests to the aquarium, namely the Montipora eating nudibranch (For more info, check out my friend Aaron and his video above).

Montipora eating nudibranchs will evade most coral dips and find their way into the aquarium regardless; some adults may die during the dipping process but eggs largely remain unscathed.

These invertebrates are small and white. They have several appendages that come out from the sides of their body that facilitate movement. They is found on the glass of the aquarium, in the substrate, or directly on the Montipora coral. It is easiest to find them at night with a flashlight.

There are a few ways to tell if you’re facing a Montipora nudibranch outbreak. These signs include:

• Exposed areas of skeleton when there are no signs of aggression from other corals and stable water parameters
• Random bleached areas of the coral away from the edge
• Egg clutches on the underside of the coral
• Visual observation of nudibranchs

Tanks are especially susceptible to Montipora eating nudibranch if introducing a wild-caught coral. In order to prevent this and to receive a hardier coral in general, it is always best to choose aqua-cultured specimens. Still, there is always the chance that nudibranchs will be introduced from an aqua-cultured setting.

The best way to avoid Montipora eating nudibranchs is by allowing enough time for quarantine. Several weeks should give enough time to observe the telltale signs of an infestation. Quarantine allows for much more aggressive treatments without having to worry about other more sensitive fish and corals that are waiting in the display.

Even then, it is possible to find nudibranchs on a quarantined piece of Montipora. At this point, it will take persistence and dedication to get rid of them. There are a few options for dealing with Montipora eating nudibranchs, and, the solution will be a combination of all methods.

One of the most aggressive ways for eliminating Montipora eating nudibranchs from the aquarium is to persistently dip the coral. This dip should be strong and administered regularly; basically, you want to dip as frequently as you can without risking damaging the coral. At the same time, check the undersides of the coral for eggs and manually remove them.

In addition to dipping the corals, you may try more organic remedies, such as introducing a wrasse that is a natural predator. In particular, the yellow coris wrasse (Halichoeres chrysus) and the six-line wrasse (Pseudocheilinus hexataenia) have proved to be the most helpful.

Your tank should be able to accommodate for long-term housing of these species, or plans should be made to safely rehome them after the nudibranchs have been eliminated. It is very unlikely that the yellow coris wrasse will solve this problem alone though and you will need to dip the corals as well.

Lastly, you need to sacrifice a piece of coral. Experienced keepers have found success in removing all Montipora from the aquarium except for one piece. This piece will act as a lure that is removed once nudibranchs have occupied it. However, as nudibranchs can live in other parts of the aquarium, this method is not always guaranteed to be completely effective.

Still, Montipora eating nudibranchs are extremely difficult to get rid of and anything is worth a try. Though these invertebrates mainly target plating Montipora, they may also go after encrusting and branching varieties as well.

Where To Buy

Montipora corals is purchased at local aquarium stores or online. I will prefer online coral vendors as they will sell what you see is what you get (WYSIWYG), offer guarantees, and have a better reputation for not having corals infected with pests.

ASD Difficulty Rating: Tier 3 – Advanced — Montipora are SPS corals that require stable, reef-quality water chemistry. A single parameter swing can bleach a colony.

Hard Rule: Montipora require stable calcium (400–450 ppm), alkalinity (8–9.5 dKH), and magnesium (1250–1350 ppm). A significant parameter fluctuation will bleach an entire colony.

Is the Montipora Coral Care. A Right for You?

Before you add a montipora coral care. A to your tank, it’s worth asking whether this species actually fits your setup and your goals. Here’s a quick breakdown to help you decide.

This species is a good fit if:

• You have an established reef tank with stable parameters. New setups are not the place for corals.
• You’re committed to regular water testing and maintenance. Reef tanks require more attention than freshwater.
• Your lighting and flow match what this coral needs. Not all corals want the same intensity.
• You understand that coral growth is slow. Patience is not optional in reefkeeping.
• You have a plan for fragging or managing growth if the colony expands beyond its space.
• You’re not adding it to a tank with known coral pests. Prevention is easier than treatment.

If most of those points line up with your setup, the montipora coral care. A is worth serious consideration. If several don’t, it’s better to choose a species that matches your tank now rather than trying to make it work.

Avoid If:

• You do not test and dose calcium, alkalinity, and magnesium regularly
• Your tank is under 40 gallons (151 L) or has inconsistent lighting and flow
• You are new to reef keeping – SPS corals require stable, high-quality parameters
• You keep coral-nipping fish like certain angelfish, butterflies, or large tangs

How the Montipora Coral Care. A Compares to Similar Species

Want easy, fast-growing coral? Start with green star polyps or zoanthids. Want a challenge? Get SPS and invest in dosing equipment.

Choosing between similar species is tricky. Here’s how the montipora coral care. A stacks up against some common alternatives.

The montipora coral care. A occupies a specific niche in the aquarium hobby, and direct comparisons really depend on what you’re looking for. In my experience, the most common question people ask is whether they should choose the montipora coral care. A or something similar that’s more widely available. The answer comes down to three things: tank size, water parameters, and what other fish you’re keeping. If your setup matches what the montipora coral care. A needs, it’s hard to beat. If not, there are alternatives worth exploring.

Closing Thoughts

Montipora is a very popular genus of hard coral to keep due to its hardiness, available varieties, and color selection compared to other species of SPS. Montipora is plating, branching, or encrusting, and requires high lighting and high water flow.

These corals is more susceptible to pests than other SPS corals, but they are very easy to frag and pretty forgiving when it comes to instability in water chemistry. They are also easy to find and is an inexpensive addition to the aquarium.

Have a question? Leave a comment below and let’s start a conversation. Welcome to the reef aquarium community :).

SPS corals are not hard to keep because of what they need. They’re hard because they don’t forgive inconsistency. I’ve watched reefers with decades of experience lose acropora colonies overnight from a single alkalinity spike. And I’ve watched beginners succeed with SPS when they built the right system and kept their hands out of it. The coral itself isn’t the obstacle. Your water column is.

Stable mediocre parameters beat perfect parameters that swing. Every time.

Small polyp stony (SPS) corals are the pinnacle of reef aquarium keeping. In the wild, corals like staghorn and table acropora build the backbone of tropical reef systems, housing thousands of species and defining the reef’s vertical structure. In the aquarium, they deliver that same visual impact at the top of the rockwork. No soft coral or LPS can replicate what a full SPS colony looks like under 400 PAR. But that beauty comes with demands that most hobbyists underestimate.

After 25 years in this hobby and time running fish stores where we sold frags and watched customers succeed and fail, here’s what I know: SPS is not the next step after soft corals. It’s a different discipline entirely.

What Is SPS Coral?

SPS stands for small polyp stony coral. These are reef-building corals in the order Scleractinia that construct calcium carbonate skeletons as they grow. Their polyps are tiny compared to LPS corals, which is where the name comes from. The skeleton is exposed and rigid, covered in a thin layer of tissue called the coenosarc that connects all the individual polyps.

Zooxanthellae, the symbiotic algae living inside coral tissue, fuel SPS growth through photosynthesis. This is why light quality and intensity matter so much: cut the PAR, cut the energy supply. Without adequate light, zooxanthellae compensate by producing darker pigments (the dreaded “brown out”) or the coral simply starves.

Taxonomically, SPS corals belong to the Scleractinia order and the Hexacorallia subclass, which means their polyp symmetry is divisible by six. In the wild, they colonize the upper reef zones where wave energy is highest and sunlight is most direct. That’s your setup blueprint right there: high light, high flow, near-constant stability.

SPS vs. LPS vs. Soft Corals

Understanding where SPS sits in the coral hierarchy is critical before you buy your first frag.

Soft corals have no true calcium carbonate skeleton. They’re held up by water pressure and small internal spicules. They’re the most forgiving: many tolerate poor lighting, inconsistent flow, and imperfect water chemistry. Great starting point for new reefers.

LPS corals have a true skeleton but large, fleshy polyps that extend outward dramatically. Most LPS live lower on the reef where flow is gentler and light is indirect. They need more stable parameters than soft corals but are still more forgiving than SPS.

SPS corals are the reef builders. Their skeleton grows continuously as long as chemistry supports it. They live at the top of the reef, need the most light, and react to water chemistry changes faster than any other coral group. A 2 dKH alkalinity swing that a leather coral shrugs off can bleach a milli acropora colony in 48 hours.

Who Should Actually Keep SPS

This is where I’m going to be direct: SPS is not for everyone, and there’s no shame in that.

You’re ready for SPS if your tank has been running stable for at least 12 months, you test alkalinity at least twice a week, you have a dosing pump or calcium reactor, your lighting can hit 200+ PAR at the rockwork, and you’ve already kept LPS successfully without unexplained deaths. If any of those aren’t true, start with Montipora and use it as your chemistry test subject.

You’re not ready if you’re still troubleshooting brown algae, your parameters swing week to week, or you’re on a hang-on-back filter with stock lighting. That’s not a judgment. That’s just chemistry.

Water Parameters

These are the target ranges I recommend based on what I’ve seen work consistently. Note that stability within range matters more than hitting exact numbers.

Parameter	Target Range	Notes
Alkalinity	8.0–9.0 dKH	Most critical; swing tolerance <0.5 dKH/day
Calcium	420–450 ppm	Linked to Alk; balance them together
Magnesium	1,300–1,350 ppm	Stabilizes Alk and Ca relationship
Nitrate (NO3)	1–5 ppm	Zero nutrients = poor color and brown out
Phosphate (PO4)	0.03–0.07 ppm	ULNS tanks brown out; some PO4 is good
Salinity	1.025 / 35 ppt	Auto top-off is non-negotiable
Temperature	76–78°F (24–26°C)	Upper end accelerates growth but reduces tolerance
pH	8.1–8.3	Tie CO2 injection to your apex controller
Lighting (PAR)	200–400+ PAR	Species-dependent; acropora needs more

Lighting and Flow

High-quality lighting is not optional for SPS. A programmable LED fixture with full spectrum control is the minimum. The EcoTech Radion G5 is the standard for serious SPS tanks for good reason: consistent spectrum, reliable PAR output, and full programmatic control over ramp-up and ramp-down so corals aren’t shocked by sudden light changes.

Water flow is equally critical. Random, turbulent flow keeps waste from settling on coral tissue, delivers nutrients to polyps, and prevents dead zones inside dense colonies. Most SPS tanks run two or more powerheads in alternating patterns. A single powerhead pointed at the rock creates a dead zone on the back side of every colony it hits.

Filtration: a sump system is standard in any SPS setup. More water volume means more stability, more room for biological filtration, and easier nutrient export. Running SPS without a sump is possible but significantly harder to maintain stable chemistry.

Types of SPS Coral

SPS corals span dozens of genera, but the hobby trades around a handful of key groups. Here’s what you’ll actually encounter.

Montipora

• Scientific Name: Montipora spp.
• Difficulty Level: Easy-Moderate
• Temperament: Non-aggressive
• PAR Requirements: 150+ PAR
• Flow Requirements: Moderate-High
• Placement: Middle to Upper
• Origin: Indo-Pacific

Montipora is the entry point for SPS. This genus covers encrusting, plating, and branching growth forms and comes in virtually every color. The plating “Monti Cap” varieties grow in large circular disks with white growth tips at the edges. Montipora digitata branches with thicker growth and produces antler-like structures over time.

Why start here? Montipora tells you if your system is SPS-capable before you invest in a $200 acropora frag. It needs SPS conditions but tolerates slightly more variation than the more demanding genera. Think of it as a living test kit. If your Monti is browning out, your nutrients are off. If the tips aren’t showing white growth, your alkalinity is low or your PAR isn’t adequate.

Read our full Montipora coral care guide for detailed setup and color optimization tips.

Pocilloporidae Family: Pocillopora, Stylophora, Seriatopora

• Scientific Name: Pocillopora spp., Seriatopora spp., Stylophora spp.
• Difficulty Level: Easy-Moderate
• Temperament: Non-aggressive
• PAR Requirements: 200+ PAR
• Flow Requirements: High
• Placement: Middle to Upper
• Origin: Indo-Pacific

The Pocilloporidae family gives you the classic “bird’s nest” look. These three genera are closely related and often confused with each other on frag discs.

Pocillopora has thick, stubby branches with a slightly fuzzy polyp extension. Most common colors are green, purple, and pink. These handle higher flow well due to their robust branch structure.

Stylophora is nearly identical to Pocillopora at the frag stage. At colony size, Stylophora grows in a more uniform, ordered pattern while Pocillopora tends to sprawl. Both are good beginner-SPS choices.

Seriatopora (the true bird’s nest) has very thin, pointed branches that create a delicate twig-like structure. Polyps sit farther apart on the branches. These are more delicate to handle and transport but frag easily. Colors range from green to purple to bi-color combinations.

Acropora

• Scientific Name: Acropora spp.
• Difficulty Level: Hard
• Temperament: Non-aggressive
• PAR Requirements: 250–400+ PAR
• Flow Requirements: High
• Placement: Upper third of tank
• Origin: Indo-Pacific (some species in Caribbean)

Acropora is the pinnacle. Full stop. A mature, multi-colony acropora display is one of the most impressive things in the aquarium hobby. There are hundreds of species, from tight table corals to elegant stag horns to intricate milli frags, and the designer trade around named morphs is its own subculture in reefing.

What makes acropora genuinely difficult: they sense chemistry changes faster than any coral I’ve worked with. They’re the canary in the coal mine. Every pump failure, every top-off malfunction, every bad water change gets reported instantly through RTN (rapid tissue necrosis) or STN (slow tissue necrosis). You don’t get the week of warning you’d get from a hammer coral. You wake up and the frag is bare skeleton.

Difficulty Tiers: Beginner to Advanced SPS

What People Get Wrong About SPS

They chase zero nutrients. The “ultra-low nutrient system” (ULNS) approach has produced countless brown, stressed acropora tanks. SPS needs zooxanthellae to produce the pigments that give it color. Zero nitrate and phosphate starves those pigments. You want 1–5 ppm nitrate and 0.03–0.07 ppm phosphate for full color expression. A completely barren nutrient profile produces a beautiful beige coral.

They think stability means weekly testing. If you’re testing alkalinity once a week on an SPS tank, you have a 7-day blind spot. Alk can swing 1–2 dKH between your tests and you’d never know until the coral starts to bleach. Twice-weekly minimum for alkalinity, calcium, and magnesium is the standard in serious SPS systems. Daily testing is common in heavy acropora tanks.

They add SPS to an immature system. Twelve months is the standard guideline because that’s roughly how long a reef system takes to establish stable bacterial populations, work through the typical algae succession phases, and reach predictable parameter behavior. An 8-month-old tank can feel stable, but the chemistry swings are often just slow enough that you don’t catch them until the coral reacts.

They confuse “hardy SPS” with “easy.” Montipora is the hardiest SPS. That doesn’t mean you can keep it on a power compact light with no dosing. It means it tolerates slightly more variation than Acropora. All SPS requires SPS conditions. Full stop.

Should You Keep SPS Coral?

Good fit if: You’ve kept a successful LPS reef for over a year, your parameter testing is already routine, you have a sump, quality lighting at 200+ PAR, and you’re willing to start with Montipora before moving to acropora. SPS is genuinely one of the most rewarding things in the aquarium hobby. A full acropora display tank is a sight that doesn’t get old. Just build toward it correctly.

Compared to LPS: If you want color and movement with more forgiveness, LPS is the better choice. Hammers, torches, and brain corals are visually stunning, reward good husbandry, and don’t punish minor parameter lapses. Choose SPS when you’re ready to go to the next level of chemistry management and want the reef structure that only branching stony corals can provide.

FAQ

What is the easiest SPS coral to keep?

Montipora capricornis (plating Montipora) and Pocillopora are the most forgiving SPS genera. They still require SPS-level lighting, flow, and stable parameters, but they tolerate minor variation better than Acropora. Frags are inexpensive and widely available, making them the standard starting point.

When can you add SPS corals to a new reef tank?

The standard recommendation is 12 months minimum. This allows enough time for the nitrogen cycle to fully establish, algae succession phases to complete, and parameter behavior to stabilize. Some experienced reefers add Montipora to well-established systems at 6–8 months, but the failure rate is significantly higher before the one-year mark.

Why are my SPS corals turning brown?

Browning out is usually caused by one of three things: too little light (increase PAR or adjust photoperiod), too much phosphate (check exports and feeding), or too little nitrate (paradoxically, zero nutrients causes the zooxanthellae that produce color pigments to compensate with darker pigments). Target 1–5 ppm nitrate and 0.03–0.07 ppm phosphate for best coloration.

Can SPS corals sting each other?

SPS corals are not aggressive in the way LPS corals are. They don’t deploy sweeper tentacles to attack neighbors. But as colonies grow and branches contact each other, tissue necrosis can develop at contact points. The bigger danger is LPS nearby: hammer and frogspawn sweeper tentacles can reach SPS and cause rapid tissue loss. Keep LPS and SPS in separate zones of the tank.

How do I frag SPS corals?

SPS frags well because the calcium carbonate skeleton cuts cleanly. Use a band saw (Gryphon C-40 is the standard), bone cutters, or a Dremel with a diamond blade for smaller pieces. Cut branches 1–2 inches (2.5–5 cm) from the colony, mount immediately on a plug or rubble with super glue gel, and dip in coral dip before placing in the tank. New frags are vulnerable to parameter swings for 2–4 weeks while they recover from the cut.

Closing Thoughts

SPS reefkeeping is one of the most technical disciplines in the aquarium hobby and one of the most rewarding. The chemistry management alone is a skill that takes time to develop. But when you get there, a mature SPS tank is something that very few hobbyists achieve and even fewer forget.

Start with Montipora. Get your dosing dialed in. Run a stable system for six months before you touch acropora. That’s not a restriction. That’s the fastest path to keeping acropora long-term.

Aiptasia is one of the most frustrating reef pests I’ve dealt with in my 125-gallon reef tank. These pest anemones showed up hitching a ride on live rock, and before I knew it they were spreading to my corals. I’ve personally tested most of the removal methods out there. from Aiptasia-X to peppermint shrimp to berghia nudibranch. and I can tell you firsthand what actually works and what doesn’t. This guide covers everything I’ve learned over 25 years of keeping reef tanks about controlling and eliminating Aiptasia for good.

Hobbyists have been fighting the battle against Aiptasia for decades, and luckily, several solutions have been found to eradicate Aiptasia once and for all.

What are Aiptaisa Anemones?

When setting up a new saltwater tank, it can be very exciting to find any signs of unexpected life during the nitrogen cycle and shortly after. Copepods start to show up on the glass and even algae can be an amazing discovery. Until suddenly, you find a small, clear what-seems-to-be coral.

These ‘corals’ have long and thin tapered tentacles and might even resemble a kind of zoanthid at first. Usually, these tentacles will be attached to an oral disc that emerges from a long, translucent stalk. Sadly, more often than not, this unidentified polyp is actually a kind of pest anemone belonging to the Aiptasia genus.

The main problem with Aiptasia Anemones is that they are both sexual and asexual; they can quickly split to create exponentially more anemones in a very small period of time. Like other species of anemone, they have stinging cells that can cause damage to nearby coral, fish, and invertebrates.

They can also grow in very hard-to-reach places in the tank where you might not even see the problem forming. Their tentacles will grow in order to reach light, though their stalks may elongate and emerge from dark crevices within the rockwork.

Naming And Other Pest Anemones

In general, all species within the Aiptasia genus are simply referred to as Aiptasia even though there are several other known members; other common names include glass anemone and rock anemone (not to be confused with rock flower anemones of the Phymathidae family).

Another type of pest anemone, Majano anemones (Anemonia manjano), may also be clumped together when talking about Aiptasia hitchhikers.

Majano anemones are said to be easier to remove than Aiptasia, but they will both cause a headache at the end of the day. Majano anemones are, in some ways, prettier than Aiptasia and have rounded green tentacles with a purplish-pink oral disc; they are typically larger, have much more opaque flesh, and overall more vibrant colors than Aiptasia.

Like Aiptasia, Majano anemones can quickly take over a tank and injure other corals and tankmates. Luckily, most of the removal methods are universal for pest anemones.

How Do They Enter The Aquarium?

Aiptasia Anemones are present in most aquarium systems. They can be very difficult to notice in dense rockwork and before you know it, you have a tank overrun by them. But how did they get there in the first place?

These anemones are hitchhikers, just like any other algae or invertebrate that unintentionally enters the aquarium. This means that they can come in on live rock, corals, or even filter media. Once established in the tank, they can then spread to every part of it, including the filtration system and sump.

In general, it’s not considered as an if these anemones will enter your system but a when.

How Do You Prevent Them From Entering The Aquarium?

Though Aiptasia Anemones will find its way into the aquarium if it wants to, there are some ways to protect your system.

Mainly, observation and preparation are key.

Observation And Identification

It might sound simple, but observation is the best way to find and destroy Aiptasia before they get the chance to destroy your reef tank.

Check and double-check new additions of live rock and coral. Use a flashlight to look in the crevices for any signs of tentacles popping up through the rockwork. Continue to check your tank daily for the next few weeks after a new addition.

It is easiest to find pest anemones when they are extended in the water instead of when they are emersed. If possible, observe live rock and corals from a quarantine system. From there, use one of the following methods to remove it.

One of the biggest mistakes beginners make is that they think an Aiptasia is a desirable coral and let it continue to grow. It is important to accurately identify the anemone first in order to go about fixing the problem. More often than not, any ‘lucky’ coral you see on new rock or a coral plug is actually an Aiptasia.

Quarantine

That being said, all new live rock and coral should be quarantined. No exceptions.

Not only does quarantine help prevent disease and illness from entering the aquarium, but it also greatly reduces the risk of inadvertently introducing Aiptasia Anemones as well.

Allowing two or more weeks of secluded observation will allow most hitchhikers to rear their ugly heads. It is much easier to fix these problems in a controlled setting than having to break down the rockwork and possibly filtration once put into a display. It also means that you can be more vigorous and widespread with treatments, such as chemical solutions.

Remove Frag Plugs

When buying new corals, they will often come on a frag plug. No matter if these corals were aqua-cultured in a controlled environment or gifted by a trusted fellow hobbyist, this frag plug should always be removed.

For one reason or another, frag plugs are notorious for carrying in unwanted hitchhikers. Aiptasia are very quick to occupy free real estate and a frag plug is no exception. Most often, these anemones are very tiny and might only be able to be seen under a magnifying glass.

When in doubt, throw it out.

Source Rock

Another way Aiptasia Anemones travels across tanks is by live rock and filter media. Many times, hobbyists share these with each other in order to seed a new tank with beneficial bacteria. Though this usually works flawlessly, there is always the chance that you’re introducing Aiptasia into the system.

If you’re really worried about introducing pest anemones via live rock or filter media, do not use what has been in another tank. Instead, use brand new dry rock and cycle the tank with another method. This way, there is no chance of having any pests come in.

The downside to this method is that many of the beneficial hitchhikers are lost as well, like copepods, and will need to be manually introduced later.

How To Get Rid of Them From Your Aquarium (The Best Ways

The key to dealing with an Aiptasia outbreak in your aquarium is acting quickly and effectively as soon as you see one appear. The longer you wait to take action, the more chance they have to grow and spread throughout the reef tank.

There are a few different methods based on the size, type, and amount of pest anemones in your saltwater tank. Whether the method works for you will also depend on several factors and Aiptasia removal could become a regular part of maintenance.

Here are the best ways to get rid of Aiptasia Anemones from your saltwater aquarium.

Manual Clean-Up

Manual removal is one of the easiest methods, but also the least guaranteed way to fully remove Aiptasia from the aquarium. This is because these anemones are capable of growing from the smallest piece of flesh leftover, and it can be very easy to miss; in fact, Aiptasia only need a single remaining cell to regenerate into a new animal.

For manual removal, you will need to be able to take the piece of rock out of the tank. Once removed, use scissors, razors, bone cutters, and whatever else you need to in order to get every last piece of anemone off of the rock. Some hobbyists split the rock in half entirely to ensure that there is no chance of the anemone coming back.

Still, it is easy to miss other smaller Aiptasia that might have already propagated or left remnants behind.

Super Glue (Cyanoacrylate)

Super glue is one of the easiest and least damaging ways to control Aiptasia Anemones, though this method does not work all of the time.

This method simply involves coating the anemone in a thick sarcophagus of superglue so that it is unable to extend. Simply remove the affected piece of rock from the aquarium and apply a healthy dollop of glue.

There are a few problems with this method, though. First, it’s not always feasible to remove the piece of rock from the reef tank. Second, the anemone is very capable of growing around the glue and out through another opening, allowing it to live; some hobbyists have even seen them come out from the other side of the rock if the opportunity presents itself.

Super glue is most effective for removable pieces of rock and small Aiptasia that can be generously coated and sealed.

Chemical Products

There are many chemical solutions on the aquarium market designed to eliminate Aiptasia from the aquarium. This method can be very effective when facing large colonies of pest anemone with sizable individuals.

One of the most popular Aiptasia removal chemicals is Aiptasia-X by Red Sea. This product needs to be applied to the surface of the oral disc of the anemone, where it is then forced to be ingested. Within a few minutes, the anemone implodes on itself, preventing regrowth and larvae from spreading throughout the rest of the reef aquarium.

Other popular brands include:

• Joe’s Juice Aiptasia Eliminator
• Salifert Aiptasia
• Blue Life Aiptasia Rx
• Reef Kalkwasser (calcium hydroxide). Though not a product specifically meant for Aiptaisa, Reef Kalkwasser can be used to create a paste that can cover the disc of the anemone in a similar fashion.

These chemicals are not effective for all reefers though, and these products can actually harm healthy corals if not applied correctly. The application can also become difficult if the anemone is situated in a hard-to-reach spot where it has time to react and retract. If only a small dosage is received, then the Aiptasia may come back stronger and start to propagate.

Other DIY Solutions

If you don’t have immediate access to chemical solutions, then you might need to make your own solution. It should be noted that these methods are very prone to failure and should only be done under close moderation.

1. Lemon juice. Lemon juice has been used to successfully remove Aiptasia Anemones. Fill a syringe with lemon juice and inject it into the anemone. The acidity will theoretically cause the anemone to die.
2. Vinegar. Similarly, vinegar can be injected and will kill Aiptasia due to its acidity.
3. Hydrogen peroxide. Hydrogen peroxide is not likely to work when only applied over the anemone. Instead, it can be used to wipe off the remaining parts of Aiptasia that are leftover from previous attempts of removal.
4. Boiling water. Boiling water can be mixed with lemon juice or vinegar or used by itself. Again, use a syringe to inject it into the anemone.

These methods have worked for some hobbyists and completely failed for others. It is necessary to gauge how much solution is entering the system as both lemon juice and vinegar can start to affect pH due to their acidity. Boiling water can also burn nearby fish and invertebrates.

If able to do so, attempt other methods first as to not encourage propagation from a failed removal.

Lasers

Lasers are an expensive solution but can be very effective at reaching hard-to-reach places without having to put your hands in the reef tank. They are a relatively new technology being introduced into the reef aquarium hobby for treating Aiptasia Anemones and come with mixed results that might not make their price worth it.

These lasers need to be very strong and capable of melting away Aiptasia anemone. The problem with this is that they are also very capable of injuring other corals, fish, and invertebrates in the process.

Some hobbyists have reported them as being completely ineffective.

Livestock (Fish And Inverts That Love Eating This Type)

Adding Aiptasia-eating fish and invertebrates to the tank system is usually a great alternative to the other methods mentioned. However, there is always a risk when adding something new to the tank.

The main problem with adding additional livestock into the reef aquarium is that many of the species recommended to add cannot discriminate between a coral and an anemone. As a result, they might start to target colonies of desired corals and leave the Aiptasia nice and healthy. It is also possible that your fish or invertebrate will successfully eat Aiptasia and then starts to eat corals, too.

Regardless, many hobbyists try their luck at adding a new fish or invertebrate species for dealing with Aiptasia problems; some can even arrange temporary housings until the anemones have been eliminated and then pass them along to another hobbyist.

Here are some of the most common fish and invertebrates species for removing Aiptasia from your saltwater aquarium.

Butterflyfish (Chaetodontidae family)

For the most part, nearly all common species of butterflyfish have been used to effectively control Aiptasia populations. It is known that butterflyfish are not considered reef-safe and it should not come as a surprise if the one you add decides to go after corals.

There are, however, a few species that seem to be more reliable than others. This includes:

• Copperband butterflyfish (Chelmon rostratus)
• Klein’s butterfly (Chaetodon kleinii)
• Pearlscale butterfly (Chaetodon xanthurus)
• Raccoon butterfly (Chaetodon lunula)

Of course, always ensure that your setup is appropriate for the species you plan on adding. Tank size, water parameters, and diet should all be arranged to accommodate a new fish.

Eating Filefish (Monacanthidae family)

Aiptasia Eating Filefish are another popular addition for dealing with Aiptasia, though they are just as likely to nip at corals. Some hobbyists have found that buying captive-bred individuals helps deter coral picking and encourages Aiptasia Anemone hunting.

Aiptasia Eating Filefish aren’t the prettiest to have in a reef tank display and some species can get very large. However, the most popular Aiptasia-eating species, like the matted filefish (Acreichthys tomentosus), stay small and can quickly take care of a pest anemone problem.

It is not unheard of for filefish to suddenly start picking at corals, though.

Peppermint shrimp (Lysmata wurdemanni)

A group of peppermint shrimp is usually the route most reefers take for dealing with pest anemones as they are small yet effective.

With multiple individuals, peppermint shrimp can be expensive and their high demand in the hobby can also make them more difficult to obtain. Not to mention that the peppermint shrimp has a very similar appearance to the camel shrimp (Rhynchocinetes durbanensis), which is not reef-safe, and can easily be confused.

Overall, peppermint shrimp have a very high success rate for dealing with Aiptasia, however, they’ll typically avoid larger ones. They have also been known to graze on zoanthids as well.

Berghia Nudibranch (Berghia stephanieae)

If you’re limited on space but still want a natural predator of Aiptasia, Berghia nudibranchs are a great short-term solution.

These nudibranchs can also be expensive and you will need a good amount of them depending on the size of your saltwater tank. Take into consideration that some fish and other invertebrates might also see them as food in the meantime just as they’re starting to hunt for anemones.

The main problem with Berghia nudibranchs is that they only eat Aiptasia. This is great in the short term when you are desperate to get rid of all visible anemones, but doesn’t serve as a very long-term solution; once your anemone supply runs out, these nudibranchs will perish.

Many hobbyists like to pass on their nudibranchs to other tanks suffering from Aiptasia so that they don’t die in the process. They can be very difficult to catch though, and often you will not be able to save them all. If you are interested in purchasing them, I recommend buying them from Salty Underground.

Closing Thoughts

Aiptasia are the last thing you want to see in your aquarium but are largely unavoidable. These ugly, fast-growing pest anemones can quickly take over a display and infiltrate filtration systems if left to grow.

There are many different methods for removing them, including chemical products, more organic solutions, and livestock recommendations. Whatever method you end up choosing, you will most likely need to also use other alternatives and keep on schedule for a few months until there are absolutely no signs of Aiptasia.

One of the best ways to prevent a pest anemone infestation is by prevention. Even then, it is good to be prepared if one ever happens to enter your system.

If your parameters are not stable, this coral will not survive the first month. Corals do not die from wrong numbers. They die from unstable numbers. The difference between a thriving reef and a dying one is consistency, not perfection.

Stable mediocre parameters beat perfect parameters that swing. Every time.

What It Is Actually Like Growing Green Star Polyp Care to A Complete Guide

Coral growth is measured in weeks and months, not days. You will stare at your frag daily and see nothing. Then one morning, you notice new polyp extension or a visible encrustation line. That moment is deeply satisfying.

Corals open and close based on lighting and flow. Learning to read your coral’s polyp extension tells you more about tank conditions than any parameter test.

Nuisance algae will grow on and around your coral. Keeping it clean without damaging the tissue takes a gentle hand and a turkey baster. This is a regular maintenance task.

The color payoff is real. A coral that looked brown in the store develops vivid greens, purples, or oranges under proper lighting over weeks. That transformation is what makes reef keeping addictive.

The Green Star Polyp Care to A Complete Guide is a go-to recommendation for newer reefers, but it is not bulletproof. Lighting, flow, and placement mistakes kill more frags than disease ever will. After maintaining reef tanks for over two decades, I know exactly where people go wrong with this coral.

More coral frags die from too much light than too little. That surprises most beginners.

Corals grow slowly and demand stable conditions for months and years. This is a long-term commitment to water chemistry, lighting schedules, and consistent maintenance.

Coral keeping is gardening with saltwater. The patience required is identical.

When it comes to Green Star Polyp Care, there isn’t much to it. The main thing is learning how fast it grows, where to place it, and how to control it. It can grow quite large if given the right conditions and some reefers have event used them to create a wall of corals!

Today’s post is all about the Green Star Poly. Come find out all there is to know about this beautiful creature with our complete guide on how best to take care of your Green Star Polyp. You’ll be glad you did!

What Most Care Guides Get Wrong About Green Star Polyp Care. A

Want easy, fast-growing coral? Start with green star polyps or zoanthids. Want a challenge? Get SPS and invest in dosing equipment.

The biggest mistake I see with green star polyp care. As is underestimating their aggression. Guides will label them “semi-aggressive” and move on. In practice, that label doesn’t tell you much. Tank layout, stocking density, and territory management all play a huge role in whether these fish coexist or constantly fight. Tank size is another area where most guides get it wrong. The minimum listed on most care sheets is exactly that, a minimum. For long-term success, especially if you’re keeping a group, I always recommend going at least one size up from whatever the guide suggests. Finally, diet gets oversimplified. Pellets alone won’t cut it. In my 25+ years keeping fish, I’ve found that variety in diet directly affects color, growth, and overall vitality. Include frozen foods, quality pellets, and occasional vegetable matter for the best results.

The Reality of Keeping Green Star Polyp Care to A Complete Guide

Lighting is the most common source of coral death. New reefers blast their corals with too much PAR on day one. Corals need to acclimate to your lighting over weeks. Starting at 50% intensity and slowly ramping up prevents bleaching and tissue recession.

Flow matters as much as light. Dead spots collect detritus on coral tissue and cause tissue necrosis. Too much direct flow strips flesh from the skeleton. Finding the right flow pattern takes observation and adjustment.

Stability beats perfection. A reef tank with slightly elevated nitrates that stays consistent will grow coral better than a tank with perfect numbers that swings every few days. Corals adapt to stable conditions. They die from instability.

Biggest Mistake New Owners Make

Placing a new coral frag in the highest-light spot of the tank immediately. Corals from a store or vendor have been in shipping bags for hours. They need low light and gradual acclimation. Blasting them with full intensity causes bleaching within days.

Frequently Asked Questions

Are green star polyps good for beginners?

Green star polyps are one of the best beginner corals available. They are hardy, tolerant of a wide range of lighting and flow conditions, and recover quickly from stress. Their fast growth and bright green coloring make them an encouraging first coral for new reef keepers.

How fast do green star polyps grow?

Green star polyps are among the fastest-growing corals in the hobby. They can spread across a rock surface within weeks and will readily colonize adjacent surfaces. This rapid growth is both a benefit and a concern, as they can overgrow and smother other corals if not managed.

Why are my green star polyps not opening?

Closed green star polyps are responding to a change in water chemistry, flow, lighting, or the presence of a pest. New polyps may stay closed for several days while acclimating. Check for pest snails, flatworms, or sudden parameter shifts. They also close at night, which is normal behavior.

Can green star polyps touch other corals?

Green star polyps will overgrow and smother other corals they come into contact with. They are mildly aggressive and should be placed on isolated rock islands with a clear gap of several inches from other coral colonies. Many reef keepers place them on separate rocks or frag plugs to control their spread.

Do green star polyps need high light?

Green star polyps are adaptable to a wide range of lighting conditions, from low to high. They will develop deeper green coloring under moderate lighting and may become lighter or brownish under very intense light. Moderate LED or T5 lighting is ideal for the most vibrant color.

Origins And Habitat

Like many other corals, green star polyps come from the warm waters of the Indo-Pacific in turbid lagoons and along shallow to moderately deep reefs. There, they is found alongside other soft corals, such as Xenia spp. and Clavularia spp..

Green star polyps are soft corals, meaning they do not have a calcium carbonate skeleton. Instead, they quickly grow as encrusting mats over rocks and other sessile objects.

Naming

In general, green star polyps are taxonomically categorized as Pachyclavularia violacea. This is a very broad name for these corals though, and it’s very likely that you have a species that is something other than Pachyclavularia violacea. The Pachyclavularia genus is also synonymous with Briareum and the two is used interchangeably for this species.

Green star polyps are a type of soft coral (Alcyonacea order) though they contain sclerites, or small pieces of skeleton, within their tissue for structure.

What Do They Look Like?

When fully spread, green star polyps look like a lawn of grass. Individually, they have a white center and eight radial green tentacles. These serrated-like tentacles come out from a purple base with tubes for every polyp.

When closed, this coral looks like a pointy, purple mat. As we’ll discuss later, these corals will be temperamental and may be closed for extended periods of time if something is unfavorable in the tank.

Varieties

There are not many variations of green star polyp and their appearance largely depends on the type of aquarium light being used. Because they are so easy to grow, they are mostly aquacultured.

There are a few varieties of green star polyp though, mainly with differences between shades of green, tentacle length, and skeleton branching.

It is very common to come across ‘neon’ varieties of green star polyps where the tentacles are fluorescent green. Other variations might have a more defined white center or more tints of yellow, though the general purple and green coloration stays the same.

Some variations of green star polyp might also be long-tentacled. It is believed that long green star polyps are hardier and grow faster than shorter ones, which will be confused with galaxea corals (Galaxea fascicularis).

Within the aquarium, there is also said to be a branching variety of green star polyp. This variety is different from the regular encrusting type and is much more rare and desirable. The problem is that it is very difficult to tell apart from others as there is little difference between small frags and no difference at all between namings.

Branching green star polyps grow outwards, away from the rock; this means that they don’t necessarily need to grow on top of rock to spread and can create archways and limbs that extend across the reef tank.

Still, green star polyps have not reached the brand-name-worthiness of other soft corals, which keeps their prices relatively low.

Galaxea spp.

To the untrained eye, green star polyps can look very similar to species of Galaxea coral. This is a costly mistake as Galaxea have long sweeper tentacles that can severely damage other corals.

These two corals look very similar and even have similar care requirements. Overall though, green star polyps are larger, less compact, and have more tapered tips. In a mat, galaxea corals can have a shaggy appearance whereas green star polyps will have a more uniform sway.

Green Star Polyp Care Guide

Green star polyps are one of the most versatile corals in the aquarium, meaning they is placed almost anywhere. The problem is that they will also spread everywhere they can.

Green star polyps do best under moderate to high reef lighting with moderate to high flow; they can withstand conditions above and below this, though low light will result in slower or minimal growth and high light can cause bleaching and algae.

These corals need moderate to high flow in order to keep algae off their purple skeleton. Because green star polyps are so concentrated, water flow needs to be able to remove any waste or debris from the top of the coral.

If water flow is inadequate, algae can start to build over the opening of the tubes, which prevents the polyps from expanding. Even more so, snails, hermit crabs, and algae-loving fish might start to crawl over or pick at this algae which can result in longer periods of retraction.

However, you also want to make sure that you don’t place your green star polyps too close to other corals. These corals grow extremely fast and won’t hesitate to grow over and shade out zoanthids or other peaceful corals.

Because of this, many hobbyists like to keep them on a rock island of their own as they will rarely grow onto the substrate. Another option is to keep them around much more aggressive coral species (like LPS corals) that should fight back any green star polyps that try to invade their space.

Another popular option for green star polyp placement is the back or the bottom of the reef tank. Many hobbyists choose to create a background of green star polyp or a lawn on a bare bottom setup. It only takes a small piece of frag to have a waving mat of green within a couple of months.

Temperament In The Aquarium

Green star polyps will not sting other corals and are very peaceful. However, they are highly invasive and will not hesitate to grow over and shade out other corals.

As mentioned before, these corals do best when isolated. You do not need to worry about other corals being stung by them, but rather taken over by them. As long as green star polyps are kept away from other, less aggressive corals, then they should stay manageable.

Though these corals aren’t known to have a powerful sting, it is still recommended to keep them away from other corals at all times to prevent aggression.

Are They Toxic?

There is some belief that green star polyps are toxic and can release damaging chemicals into the aquarium when stressed, like zoanthids. However, this is largely a myth and has yet to be proven within the hobby.

If you are concerned about green star polyps releasing toxins, use gloves when handling and run activated carbon. Otherwise, it is extremely rare, if not impossible, to have any toxin complications due to green star polyps.

Care And Maintenance

Green star polyps are one of the easiest corals to care for, though experienced keepers can have difficulty with them due to the reef tank being too clean, inadequate flow, or extreme lighting.

Otherwise, green star polyp maintenance and upkeep are straightforward.

Dosing

Like other corals, green star polyps need available nutrients in the water column. They need nitrates, phosphates, magnesium, calcium, and a stable alkalinity for healthy growth and vibrant colors.

That being said, these soft corals do not need additional nutrients to be dosed other than what is introduced through feedings and fish waste. In fact, many hobbyists look to slow down green star polyp growth rather than speed it up.

Feeding

Many hobbyists choose not to feed their green star polyps as they get the majority of their food through photosynthesis, but they’ll definitely enjoy some supplemented foods every now and then.

For best results, use a powder or liquid food, like zooplankton; these corals are not able to take in larger foods through their mouths.

Trimming And Algae

Green star polyps grow fast, and eventually, you will need to control that growth. Experienced keepers choose to frag these trimmings, though the supply might outweigh the demand.

These corals is difficult to completely remove from a surface and will often grow back after some time. When you see green star polyps growing somewhere you don’t want them, simply scrape them off and dispose of them. Make sure you get all the pieces as they can reseed themselves elsewhere in the tank.

Another way to combat green star polyp growth is by shading it out with a larger object. This can affect other corals too if not carefully placed, but it is an effective way to deprive the coral of necessary light for growth.

At the same time, you will want to look out for algae growing on the mat of the coral. I recommend you use a turkey baster weekly to gently remove any algae or debris that is caught. If you notice that your green star polyps have been closed more than usual lately, it is bothersome algae.

What Are Good Tankmates?

Green star polyps is kept with nearly everything, including not reef-safe species. Here’s how.

In theory, green star polyps is kept with anything from clownfish and tangs to triggers and angels. This is due to the fact that this coral grows so incredibly fast. There is still the very real possibility that not reef-safe fish will eat green star polyps, but these corals are very likely to bounce right back and make up for what had been lost.

It should also be noted that green star polyps might not look as appetizing as other fleshy large polyp stony (LPS) corals, so some coral-hungry fish might leave it alone. If you find yourself with a fish that eats everything you put into the tank but you’re still determined to have corals, then get an inexpensive frag of green star polyps and try your luck.

Fragging

It should come as no surprise that green star polyps are incredibly easy to frag. The hardest part will be separating the pieces from the rock.

In order to frag green star polyps, first, find a manageable side of the rock where the mat will be easy to separate. If you can’t find a good place to cut, then choose the best spot and use a scissor, scalpel, or razor blade to cut through and detach the piece from the rock.

For the most part, it doesn’t matter how big or small of a piece you frag as it will quickly recover and start growing. Simply attach the frag to a frag plug with superglue (cyanoacrylate). You may dip this frag in iodine or a special coral mix, but this is not necessary.

Place the frag towards the bottom of the reef tank. The polyps should start to open in a few days, though these corals is temperamental after handling. Do not worry as they can survive a couple of weeks of being retracted.

As mentioned before, your green star polyps may grow too quickly for how much fragging you can manage. These excess corals is moved to the sump to help with nutrient exportation, given to another hobbyist, or disposed of correctly. If you want a video tutorial, you can check out the video below by OceanStateAquaticsTV.

How Long Does It Take For Them To Spread?

Green star polyps can cover a rock in a matter of months. Growth may be slow initially and your coral might not even open for a few days when you first introduce it into the reef tank.

If conditions are right though, you will have new growth almost every day. This is seen on the edges of the mat, where the flesh is light purple or white instead of the dark reddish-purple of the rest of the colony.

If you find that your green star polyps aren’t opening, try to keep conditions stable. You will want to move them around to new areas of the tank for better flow or lighting, but it is best to leave them where they are until they open. If you see algae starting to grow on top of the mat, gently waft away or turkey baster the algae off.

At the same time, make sure there are available nutrients in the water column. It is not unheard of for green star polyps to not open when sufficient nutrients aren’t available.

Is the Green Star Polyp Care. A Right for You?

Before you add a green star polyp care. A to your tank, it’s worth asking whether this species actually fits your setup and your goals. Here’s a quick breakdown to help you decide.

This species is a good fit if:

• You have a large enough tank to manage territories. Cramped conditions amplify aggression.
• You’re comfortable managing aggression through stocking ratios, line of sight breaks, and tank layout.
• You can commit to regular water changes. These fish produce more waste than many smaller species.
• You’re not planning a peaceful community tank. Green Star Polyp Care. As need tank mates that can hold their own.
• You enjoy watching active, interactive fish. Cichlids have personality that smaller species simply don’t match.
• You have backup plans. Sometimes a particular fish just doesn’t work out, and you need a way to rehome it.
• You’re feeding a varied, high-quality diet. Color and health depend on nutrition.

If most of those points line up with your setup, the green star polyp care. A is worth serious consideration. If several don’t, it’s better to choose a species that matches your tank now rather than trying to make it work.

Avoid If:

• Your reef has insufficient flow – GSP needs strong, consistent water movement or it closes permanently
• You keep it in a mixed reef with LPS or SPS corals – GSP grows aggressively and will overgrow neighbors within months if not isolated
• You want low-maintenance coral – GSP requires regular fragging and isolation management to prevent it from dominating the rockscape

How the Green Star Polyp Care. A Compares to Similar Species

Want easy, fast-growing coral? Start with green star polyps or zoanthids. Want a challenge? Get SPS and invest in dosing equipment.

Choosing between similar species is tricky. Here’s how the green star polyp care. A stacks up against some common alternatives.

The green star polyp care. A occupies a specific niche in the aquarium hobby, and direct comparisons really depend on what you’re looking for. In my experience, the most common question people ask is whether they should choose the green star polyp care. A or something similar that’s more widely available. The answer comes down to three things: tank size, water parameters, and what other fish you’re keeping. If your setup matches what the green star polyp care. A needs, it’s hard to beat. If not, there are alternatives worth exploring.

Closing Thoughts

Green star polyps are one of the best corals and one of the worst corals. They offer vibrant colors and exciting movement to all levels of the aquarium, but they can easily outcompete other species and be extremely difficult to remove once introduced to the tank.

They are one of the best beginner corals due to their resilience and relatively low care requirements, but can also make a beautiful backdrop or lawn for more intricate setups.

Soft corals are where most reef keepers start, and for good reason. They’re forgiving of imperfect parameters, don’t require the calcium dosing that stony corals demand, and add movement and color to a reef tank that fish alone can’t deliver. But “easy” is relative. I’ve seen toadstool leathers that wouldn’t open for three months in a perfectly maintained reef, and I’ve seen GSP overgrow an entire tank’s rockwork in six months. Soft corals have their own personalities and their own quirks, and some of them will test your patience before they reward you.

The most important rule for any soft coral reef: stable mediocre parameters will always beat perfect parameters that swing. Corals don’t die from wrong numbers. They die from unstable numbers. Get that principle right before anything else.

When Can You Add Soft Corals?

Not in the first 3 months. That’s the short answer. A new reef tank is cycling through diatoms, nuisance algae, parameter swings, and biological establishment. Adding corals into that process is expensive and usually disappointing. Wait until:

• The nitrogen cycle is complete and parameters are stable for at least 4 weeks
• Algae blooms (diatoms, hair algae) have cycled through and reduced
• You’ve established a stable lighting schedule
• You understand how your tank’s nutrient levels respond to feeding and water changes

After 3 to 6 months, you have a mature system. That’s the point where soft corals will actually establish and grow rather than decline and die.

The 9 Best Soft Coral Types for Reef Tanks

1. Zoanthids

Scientific Name	Zoanthus spp.
Difficulty Level	Easy to Moderate
Temperament	Can be aggressive via chemical warfare
PAR Requirements	Moderate (50 to 150 PAR)
Flow Requirements	Moderate
Placement	Middle to high
Origin	Worldwide in warm, shallow waters

Zoanthids (“zoas”) are the most popular soft coral in the hobby and for good reason: they come in an extraordinary range of colors, they’re easy to frag, and they thrive under a wide variety of conditions. Collector zoa morphs have commanded prices in the hundreds to thousands of dollars per polyp, though common varieties are inexpensive and just as hardy.

Two things to know about zoanthids before you add them. First, they contain palytoxin, one of the most toxic natural substances known. Don’t let water splash in your eyes or mouth when handling them. Wear gloves and rinse rock fragments carefully. This is not a hypothetical risk. Second, zoanthids prefer slightly nutrient-rich water. In a very clean, nutrient-poor system optimized for SPS, they often underperform. If your zoas are closed, the answer is usually stability, not perfection.

2. Mushroom Corals (Discosoma and Rhodactis)

Scientific Name	Discosoma spp., Rhodactis spp.
Difficulty Level	Easy
Temperament	Semi-aggressive via sweeper tentacles
PAR Requirements	Low to Moderate (under 50 to 150 PAR)
Flow Requirements	Low
Placement	Bottom to middle, shaded areas
Origin	Widespread: Australia, Tonga, Caribbean, Indonesia

Mushroom corals are among the easiest reef animals to keep and one of the best starting points for a new coral reef. They thrive under low to moderate light, need minimal flow, and reproduce by splitting and spreading on their own. Discosoma mushrooms (the flat, round type) are extremely forgiving. Rhodactis mushrooms have a more textured, hairy surface and grow larger, capable of catching and consuming small fish or shrimp.

The spread potential is real. A single Discosoma mushroom can become a colony of dozens within a year. Keep them on their own rock if you want control, or let them colonize the lower shaded areas of the tank naturally.

3. Ricordea Mushrooms

Scientific Name	Ricordea florida, Ricordea yuma
Difficulty Level	Easy to Moderate
Temperament	Semi-aggressive
PAR Requirements	Low to Moderate (under 50 to 150 PAR)
Flow Requirements	Low to Moderate
Placement	Bottom to middle
Origin	Caribbean (R. florida), Indo-Pacific (R. yuma)

Ricordea mushrooms are the collector’s version of the mushroom coral. The colors available in R. yuma especially are extraordinary: orange, blue, green, multicolored patterns. They’re more expensive than Discosoma mushrooms and slightly more sensitive to parameter swings. They need more stable water and don’t tolerate aggressive flow or bright light as well. For a mature, stable system, they’re one of the most visually rewarding soft corals available.

4. Toadstool Leather Coral

Scientific Name	Sarcophyton spp.
Difficulty Level	Easy
Temperament	Peaceful but releases chemicals during shedding
PAR Requirements	Low to Moderate (under 50 to 150 PAR)
Flow Requirements	Moderate to High
Placement	Bottom to top depending on size
Origin	Indo-Pacific

The toadstool leather is a statement piece. It can grow 2 feet (60 cm) across given time and space, with polyps that wave in the current like a living mushroom. Colors are limited (greens, browns, tans, yellows), but the movement and size it adds to a reef tank are hard to replicate with any other coral.

The behavior that trips beginners up: toadstool leathers periodically close completely and shed a thin waxy coat. This is normal. It’s not dying. The shedding process clears algae and debris from the surface. It can last days to weeks. The coral that looks completely dead today will open and look perfect next week. The shedding also releases compounds that can irritate neighboring corals. Run activated carbon during and after shedding periods.

5. Devil’s Hand Leather

Scientific Name	Lobophytum spp.
Difficulty Level	Easy
Temperament	Peaceful
PAR Requirements	Low to Moderate (under 50 to 150 PAR)
Flow Requirements	Moderate to High
Placement	Bottom to top
Origin	Indo-Pacific

Devil’s hand corals are a leather coral with distinctive finger-like lobes that give it the common name. They have shorter tentacles than toadstools and a more structured appearance. Like the toadstool, they shed periodically and release compounds during the process. They do best in moderate to high flow to help clear shed material. A good alternative to the toadstool if you want the leather coral category with a different shape profile.

6. Green Star Polyp (GSP)

Scientific Name	Pachyclavularia spp.
Difficulty Level	Easy
Temperament	Invasive spreader
PAR Requirements	Low to High (under 50 to 200+ PAR)
Flow Requirements	Moderate to High
Placement	Any level, but isolate on its own rock
Origin	Indo-Pacific

Green star polyp is one of the most vigorous corals in the hobby. It adapts to a wide range of light levels, grows fast, and produces that iconic carpet of shimmering green polyps waving in the current. It looks spectacular on a back wall or as a frag on an isolated rock.

The problem is containment. GSP will spread onto any surface it contacts: rock, glass, other corals, equipment. Once established on your rockwork, it’s nearly impossible to fully remove. The standard practice is to keep it on a separate rock island surrounded by sand. If it touches your main rockscape, it will colonize it. This is not a fish-hobby warning that’s overblown. It genuinely happens fast. Plan for it before you add it, not after.

7. Pulsing Xenia

Scientific Name	Xenia spp.
Difficulty Level	Easy
Temperament	Invasive spreader, chemical aggressor
PAR Requirements	Low to Moderate (under 50 to 150 PAR)
Flow Requirements	Low to Moderate
Placement	Isolate: sand islands or back wall only
Origin	Indo-Pacific

Pulsing xenia is the most polarizing soft coral in the hobby. The pulsing motion of its polyps is genuinely mesmerizing and adds movement that no other coral produces. It also spreads aggressively, can take over a tank if not managed, and releases compounds that suppress other corals’ growth. Some reefers love xenia. Others refuse to put it in their tank ever again.

If you want xenia, isolate it. A back wall away from other corals, or a sand island. Frag regularly to control spread. If you can’t commit to active management, skip it. A xenia colony that gets out of hand is a tank-wide problem.

8. Kenya Tree Coral

Scientific Name	Capnella spp.
Difficulty Level	Easy
Temperament	Peaceful but spreads aggressively
PAR Requirements	Low to Moderate (under 50 to 150 PAR)
Flow Requirements	Low to Moderate
Placement	Middle; watch for branch-drop spread
Origin	Indo-Pacific

Kenya tree corals propagate by dropping branches that settle on the substrate and establish new colonies. This is unusual behavior and makes them very difficult to control once they’re established. They’re not aggressive toward neighboring corals via chemical warfare (unlike zoanthids and xenia), but they will shade out and overgrow neighbors by sheer physical expansion.

In a large tank where spreading is acceptable, they add interesting branched structure. In a smaller, more tightly managed reef, they require regular pruning. Beginners should know what they’re committing to before placing one.

9. Pipe Organ Coral

Scientific Name	Tubipora musica
Difficulty Level	Intermediate
Temperament	Peaceful
PAR Requirements	Low to Moderate (under 50 to 150 PAR)
Flow Requirements	Moderate to High
Placement	Bottom to middle
Origin	Indo-Pacific and Western Pacific

The pipe organ coral is technically a soft coral but builds a rigid red calcium carbonate skeleton. That skeleton gives it the common name: it looks like a pipe organ, with parallel tubes in deep red. It needs calcium and alkalinity management closer to what LPS corals require, which puts it in a different category than the rest of this list. Not a beginner coral, but a stunning intermediate choice for reefers ready for more demanding species.

Soft Coral Comparison at a Glance

Chemical Warfare: What No One Tells You About Mixing Soft Corals

Soft corals compete chemically. They release terpenes and other compounds into the water column that suppress the growth of neighboring corals. This is a real phenomenon, not a hobbyist myth, and it’s one of the reasons coral placement matters more than most beginners realize.

The practical consequences:

• Never allow direct contact between different soft coral species, or between soft corals and LPS/SPS
• GSP and leather corals are particularly aggressive chemical competitors
• Xenia suppresses some LPS growth even without contact
• Running activated carbon helps remove dissolved organics and chemical compounds
• Regular water changes dilute allelopathic compounds and reduce coral stress

A soft coral reef that looks beautiful today can have hidden stress building beneath the surface from chemical competition. Watch for closed polyps, reduced polyp extension, or pale coloration in neighboring corals as warning signs.

What People Get Wrong About Soft Corals

The first misconception is that soft corals are foolproof. They’re not. A toadstool leather that closes and doesn’t open for six weeks can cause genuine panic. A zoanthid colony that won’t open in a perfectly maintained tank is genuinely frustrating. “Easy” means they’re forgiving of imperfect water. It doesn’t mean they’re immune to tank conditions or placement problems.

The second misconception is about GSP and xenia. Both are sold as beginner corals. Both are genuinely easy to keep. Both will also take over your tank if you’re not managing them actively. Know this before you add them, not after they’ve colonized your main rockwork.

The third misconception is about placement. Soft corals need space between them and other corals. “Near each other” is not a valid placement strategy for corals that engage in chemical warfare. Spread them out. Give each species its own rock or zone.

FAQs

Closing Thoughts

Soft corals are the right starting point for reef keeping. They’re affordable, forgiving, and visually rewarding in a way that a fish-only tank can’t replicate. A toadstool leather, a patch of zoas, a mushroom colony, and maybe a frag of GSP on its own rock: that’s a reef. It’s not complicated. It just takes a stable tank, reasonable parameters, and patience.

The one piece of advice I’d emphasize above everything else: stable mediocre parameters beat perfect parameters that swing. Keep your salinity, temperature, and alkalinity consistent and your soft corals will reward you with fast growth and full polyp extension. Chase perfection with swings and they’ll stay closed and stressed.

Happy reefing. If you’re looking to source quality soft corals, both Flip Aquatics and Dan’s Fish carry corals and reef livestock shipped directly to your door.

If your parameters are not stable, this coral will not survive the first month. Corals do not die from wrong numbers. They die from unstable numbers. The difference between a thriving reef and a dying one is consistency, not perfection.

Stable mediocre parameters beat perfect parameters that swing. Every time.

What It Is Actually Like Growing Bubble Coral Care to A Complete Guide

Coral growth is measured in weeks and months, not days. You will stare at your frag daily and see nothing. Then one morning, you notice new polyp extension or a visible encrustation line. That moment is deeply satisfying.

Corals open and close based on lighting and flow. Learning to read your coral’s polyp extension tells you more about tank conditions than any parameter test.

Nuisance algae will grow on and around your coral. Keeping it clean without damaging the tissue takes a gentle hand and a turkey baster. This is a regular maintenance task.

The color payoff is real. A coral that looked brown in the store develops vivid greens, purples, or oranges under proper lighting over weeks. That transformation is what makes reef keeping addictive.

The Bubble Coral Care to A Complete Guide is a go-to recommendation for newer reefers, but it is not bulletproof. Lighting, flow, and placement mistakes kill more frags than disease ever will. After maintaining reef tanks for over two decades, I know exactly where people go wrong with this coral.

More coral frags die from too much light than too little. That surprises most beginners.

Corals grow slowly and demand stable conditions for months and years. This is a long-term commitment to water chemistry, lighting schedules, and consistent maintenance.

Coral keeping is gardening with saltwater. The patience required is identical.

Proper Bubble Coral Care is a little more complicated than other types of corals. They require specific lighting and water parameters to thrive, so it’s important that you take the time to learn what they need before adding them to your tank! This guide will walk you through all the steps for setting up a bubble coral system and caring for these delicate creatures. Let’s get started!

What Most Care Guides Get Wrong About Bubble Coral Care. A

Want easy, fast-growing coral? Start with green star polyps or zoanthids. Want a challenge? Get SPS and invest in dosing equipment.

Many care guides make the bubble coral care. A sound easier than it really is. They’ll list basic parameters and call it a day. In my experience running reef systems, stability matters far more than hitting a perfect number. Flow and placement get glossed over constantly. I’ve seen perfectly healthy bubble coral care. A colonies stress and close up simply because they were in the wrong spot. Getting flow right is half the battle. The other mistake is overfeeding or over-supplementing. More is not better with corals. Clean water and patience will outperform any additive regimen.

The Reality of Keeping Bubble Coral Care to A Complete Guide

Lighting is the most common source of coral death. New reefers blast their corals with too much PAR on day one. Corals need to acclimate to your lighting over weeks. Starting at 50% intensity and slowly ramping up prevents bleaching and tissue recession.

Flow matters as much as light. Dead spots collect detritus on coral tissue and cause tissue necrosis. Too much direct flow strips flesh from the skeleton. Finding the right flow pattern takes observation and adjustment.

Stability beats perfection. A reef tank with slightly elevated nitrates that stays consistent will grow coral better than a tank with perfect numbers that swings every few days. Corals adapt to stable conditions. They die from instability.

Biggest Mistake New Owners Make

Placing a new coral frag in the highest-light spot of the tank immediately. Corals from a store or vendor have been in shipping bags for hours. They need low light and gradual acclimation. Blasting them with full intensity causes bleaching within days.

Expert Take

Start your lights at 50% and increase by 10% every two weeks. More corals die from too much light too fast than from any disease I have encountered in 25 years of reef keeping.

Frequently Asked Questions

Is bubble coral good for beginners?

Bubble coral is a moderate-difficulty LPS coral. While not the easiest for absolute beginners, it is a great next step after mastering basic soft corals. It requires stable water parameters and moderate lighting, but is hardy once established.

Why is my bubble coral not inflating?

A bubble coral that refuses to inflate is stressed by high flow, improper lighting, or poor water quality. Check your flow direction to make sure it is not blasting the coral directly, verify your parameters, and give it time to acclimate. Newly placed corals may take a few days to fully expand.

Can bubble coral sting other corals?

Yes, bubble coral has sweeper tentacles that can extend several inches at night. These tentacles can sting nearby corals and damage their tissue. Give bubble coral at least 6 inches of space from neighboring corals to prevent chemical warfare.

How do you feed bubble coral?

Bubble coral benefits from target feeding with meaty foods like mysis shrimp, brine shrimp, or small pieces of fish. Feed once or twice a week by gently placing food near the tentacles. The coral will capture the food and draw it into its mouth.

Where should bubble coral be placed in a reef tank?

Place bubble coral in the lower to middle area of your tank on a flat, stable surface. It prefers moderate, indirect flow and moderate lighting. Avoid placing it directly under metal halides or high-output LEDs, as too much light can cause bleaching.

Origins And Habitat

Bubble corals come from a wide range of environments. They have been found in dark and turbid waters as well as bright and clear seas.

Bubbles are largely found throughout the Indo-Pacific and the Pacific Ocean, but most available colonies in the hobby originate from Indonesia specifically; more Australian colonies have entered the trade due to difficult propagation and trading bans on coral.

Naming

These corals are commonly known as the bubble coral, grape coral, or pearl coral due to their appearance. Though they have previously been categorized as a member of the Euphylliidae family, their exact taxonomic categorization is largely up for debate and still unknown.

The common name ‘bubble coral’ is actually used to describe two different genera, Plerogyra and Physogyra. The difference between these two genera is that Plerogyra spp. have larger bubbles and a blade-like skeleton while Physogyra spp. have smaller bubbles with a flatter skeleton; Physogyra spp. are often referred to as pearl bubbles¹.

Some of the most common species to come across are Plerogyra sinuosa and Physogyra lichtensteinii. Luckily, the care requirements for these two genera do not differ.

In the aquarium hobby, these corals may be further named according to their area of collection. For example, you may come across ‘Aussie bubble corals’, ‘Indo bubble corals’, ‘Marshall Island bubble corals’, or wherever else they might have been collected from; these names may even be carried over for those corals that have been aquacultured.

Experienced keepers find Aussie bubbles to be more sensitive than Indo bubbles, but this is specific to each tank.

What Do Bubble Corals Look Like?

These corals look exactly how you might imagine them. Bubble corals are large polyp stony corals (LPS) with a calcium carbonate skeleton and round fleshy polyps. They can grow to be several inches across and reach reasonable heights.

There are two main types of bubble coral variety:

• Ones with rounded, grape-shaped bubbles; some of these that have smaller bubbles may also be labeled as ‘pearl’ (Physogyra spp.)
• Ones with irregularly shaped bubbles

No matter what kind of bubble coral you have, your coral should always be fully extended. The level of polyp expansion can correlate to lighting. Low lighting can cause your coral to inflate more in order to optimize photosynthesis and high lighting can cause more compacted bubbles.

Bubble corals have very jagged skeletons which can easily puncture their own bubbles. This can make transporting them very difficult, but not impossible. For as fragile as they are, hobbyists have found them to be incredibly resilient and can come back from near death.

Along with being fully extended, your bubble coral should have bright colors; though they do not come in many different colors, the greens, whites, yellows, and pinks of your coral should be vibrant. Bubble corals have almost transparent flesh, but color should never be entirely absent.

At night, these corals retract their bubbles. They send out long, clear sweeper tentacles that are used for feeding and attacking any corals that get too close; these tentacles do have nematocytes, or stinging cells, which can cause some irritation or inflammation to human skin and even more damage to nearby corals.

During this time, the skeleton will be exposed and you will be able to see how jagged it really is. Remember, this skeleton should never be exposed at any other time.

Placement In The Aquarium

Bubble corals aren’t the most popular coral in the hobby, but they’re one of the most adaptable.

These corals is placed in nearly all locations of the aquarium as long as adequate acclimation is allowed for and care is given when handling; these corals is more top-heavy than others, so long-term placement needs to be secured with superglue (cyanoacrylate) or epoxy.

Do They Like High Water Flow?

No, bubble corals do best with low to moderate water flow. Flow should be just enough to keep the bubbles slightly moving – aim for gentle water movement. Anything more than this could damage the coral.

Moderate flow is needed for these corals to remove algae and debris as well as to keep them fed. At night, they use their sweeper tentacles to help catch food that needs to be moved past them with a current.

How Much Light Do They Need?

Naturally, bubble corals are found in a variety of light intensity conditions. They can withstand lower light (50 PAR) on the substrate or be acclimated to the top (150 PAR) of the reef.

Because of how large they can get and how delicate they are if they fall, most hobbyists choose to keep them on or near the substrate. If choosing to keep them on the sand, make sure that the water flow is not pushing granules onto the coral. This can cause irritation which can lead to retraction and infection.

Wherever you choose to place them, they should be secure and away from anything that could rub up against them, like rock, the aquarium glass, or other corals.

Temperament In The Aquarium

Though bubble corals might look harmless, they need to be given their space in the aquarium. Their sweeper tentacles are relatively long and very capable of inflicting a sting on nearby corals.

It is difficult to judge placement in the aquarium at first as these sweeper tentacles only emerge at night. In general, it is best to leave about 5-6 inches of buffer room for your coral to fully expand and extend its tentacles.

It also isn’t uncommon for your bubble coral to change shapes throughout the day. When the lights come on, your bubble may still have its sweeper tentacles out with a lot of exposed flesh. As the day goes on and the light reaches higher intensities, it may form more compact bubbles.

Care And Maintenance

Bubble corals aren’t the easiest species of LPS, but they don’t require much special care either. As mentioned before, the biggest concern with these corals is transporting them and acclimating them correctly.

Otherwise, they need standard reef conditions and is kept with hang on the back, canister, or sump filtration. If you start to notice algae growing around the skeleton, it should be carefully removed with a turkey baster or by hand to prevent it from smothering the polyps.

Dosing

Bubble corals do not need any additional nutrients as long as a quality marine salt mix is being used. The main nutrients these corals need are nitrates, phosphates, calcium, magnesium, and stable alkalinity; contrary to once-popular belief, corals need available nitrates and phosphates for the best health.

Because bubble corals make their own skeletons, they heavily rely on calcium, magnesium, and alkalinity for steady growth. These parameters are maintained through regular water changes, though they need to be dosed if keeping larger colonies of LPS and/or keeping small polyp stony corals (SPS) as well.

Simply track how parameters change in the tank between water changes. This will show how nutrients are being used and recycled throughout the system. If levels fall too much, then it is time to start dosing; make sure to only dose what is needed.

Feeding

Unlike other species of LPS, bubble corals appreciate being fed every now and then. They get the majority of their food from the water column, but will willingly accept any supplemental feedings.

In fact, these corals is fed relatively larger pieces of meaty foods like fish, shrimp, and crab in addition to smaller foods like brine shrimp, mysis shrimp, and coral-specific products. A great coral food to try is reef-roids.

Simply place the food near the mouth of the coral and wait for it to start moving it in. Do not overfeed as this can create unnecessary waste and start to stress out your coral in the long run.

What Are Good Tankmates?

Bubble corals are one of the most tankmate-friendly coral options available. As long as it’s reef-safe, there’s a good chance it will get along with your bubble.

Again, the main concern you should have is keeping your bubble coral undamaged. Anything with pincers or sharp teeth, like crabs or triggerfish, could easily damage your coral. Otherwise, tangs, gobies, damsels, and wrasses are all possible options.

Unlike other LPS with longer tentacles, clownfish do not host bubble corals nearly as much. Though bubbles don’t bring as much movement to the aquarium as other similar corals, you don’t have to worry about losing your colony to an overly aggressive clownfish.

Fragging

Fragging bubble corals is not recommended for any hobbyist. But if you’re dealing with an overgrown coral, fragging is your only option.

This process is most likened to fragging a wall hammer coral in terms of difficulty. I recommend you attempt fragging a bubble coral only if an electric saw is available. Here is a great video by MileHighReefers that shows the fragging process. I’ll provide a summary below.

There are two main ways to frag your bubble coral:

1. Just go for it. If choosing this method, first make sure all polyps are closed as much as they is. Do this by lightly touching the coral, making sure not to cause injury. Next, look for already-defined lines of division; if your bubble coral is branched, divide the branches. It is not recommended to cut through the mouth or the flesh unless highly experienced.
2. Have some patience. This method takes a little more time but have higher success rates, especially if needing to split a large polyp. First, use a rubber band to divide the polyp; you want to force the coral to separate into two. From here, you will have a defined line that is cut with a saw or, if done carefully, a Dremel tool.

Both of these methods carry high failure rates, though bubble corals are known for bouncing back pretty quickly if something goes wrong.

Why Is Your Coral Dying?

There are three main reasons your bubble coral is dying: water flow, injury, or water parameters.

Bubble corals need some flow to deliver food and to keep them clean, but anything more than enough will damage their delicate flesh. If you notice your coral start to close up or recede from the base, check how much direct flow it is receiving and move accordingly.

Injury and infection are the biggest killers for bubble corals and often happens during transportation. When purchasing a coral, but sure that it is fully extended and shows good coloration. Make sure to handle the coral from the base to prevent any further stress or injury; use a coral dip or iodine to facilitate healing. Brown jelly infections are also another common issue with bubble corals.

Unfavorable aquarium water parameters, including lighting conditions, can also cause your coral to die back., other corals in the tank will also show signs of poor water quality, but LPS can recede very quickly once started. If you recently moved your coral to a higher spot in the tank and it is failing to extend, then you might not have allowed enough time for acclimation.

ASD Difficulty Rating: Tier 2 – Intermediate — Bubble corals are beautiful but extend sweeper tentacles at night that sting and kill neighboring corals.

Hard Rule: Bubble corals extend long sweeper tentacles at night that will sting and kill neighboring corals. Keep at least 6 inches (15 cm) of clear space around them at all times.

Is the Bubble Coral Care. A Right for You?

Before you add a bubble coral care. A to your tank, it’s worth asking whether this species actually fits your setup and your goals. Here’s a quick breakdown to help you decide.

This species is a good fit if:

• You have an established reef tank with stable parameters. New setups are not the place for corals.
• You’re committed to regular water testing and maintenance. Reef tanks require more attention than freshwater.
• Your lighting and flow match what this coral needs. Not all corals want the same intensity.
• You understand that coral growth is slow. Patience is not optional in reefkeeping.
• You have a plan for fragging or managing growth if the colony expands beyond its space.
• You’re not adding it to a tank with known coral pests. Prevention is easier than treatment.

If most of those points line up with your setup, the bubble coral care. A is worth serious consideration. If several don’t, it’s better to choose a species that matches your tank now rather than trying to make it work.

Avoid If:

• You have a small or densely packed reef where spacing around corals is limited
• You cannot maintain stable parameters – bubble corals are sensitive to alkalinity and calcium swings
• You keep fish that nip or chew coral tissue, such as triggers or certain angelfish
• You are new to coral care and want something more forgiving as a first coral

How the Bubble Coral Care. A Compares to Similar Species

Want easy, fast-growing coral? Start with green star polyps or zoanthids. Want a challenge? Get SPS and invest in dosing equipment.

Choosing between similar species is tricky. Here’s how the bubble coral care. A stacks up against some common alternatives.

The bubble coral care. A occupies a specific niche in the aquarium hobby, and direct comparisons really depend on what you’re looking for. In my experience, the most common question people ask is whether they should choose the bubble coral care. A or something similar that’s more widely available. The answer comes down to three things: tank size, water parameters, and what other fish you’re keeping. If your setup matches what the bubble coral care. A needs, it’s hard to beat. If not, there are alternatives worth exploring.

Closing Thoughts

Bubble corals are easy to care for, but fragging and any excessive handling can cause problems. They don’t come in many colors, but their inflated appearance and full expansion bring life to the middle and lower regions of the tank. With some acclimation, they can even be moved to the top of the reef!

After growing corals in my own reef setups, if your parameters are not stable, this coral will not survive the first month. Corals do not die from wrong numbers. They die from unstable numbers. The difference between a thriving reef and a dying one is consistency, not perfection.

Stable mediocre parameters beat perfect parameters that swing. Every time.

Origins And Habitat

Like so many other species, the toadstool leather coral is commonly found throughout the Indo-Pacific off the coasts of Fiji, Australia, Tonga, and the Solomon Islands. These corals thrive in shallow, mixed reefs where they often grow into huge plates that can quickly overshadow life below.

Though they will always grow towards the light, toadstool corals an be seen growing at most levels of the reef. If they are overshadowed by another coral, they can easily extend their stalk so that tentacles are once again at optimal lighting conditions.

What Is It?

In conversation, toadstool corals are regularly referred to as leather corals. However, there are actually several genera of leather coral, which can get confusing as they look and act pretty similar to one another; they are also all soft corals that lack an internal skeleton structure.

The most common species of leather coral to come across in the aquarium hobby are:

• Sarcophyton spp. are types of toadstool leather coral. Both Sarcophyton spp. and Lobophytum spp. have dimorphic polyps which means that some tentacles are extended while others stay in the flesh of the coral; toadstool leather corals have much longer extended tentacles than the other genera.
• Lobophytum spp. include devil’s hand leather corals. These corals also have dimorphic polyps, though their extended tentacles are much shorter and less present than those of toadstool corals. Devil’s hands are popular for their unique claw-shaped formations instead.
• Sinularia spp. are even more branched than Lobophytum spp. and are largely referred to as finger corals. These corals have small tentacles close to the flesh of the coral that can make for a fuzzy appearance.

Other leather coral genera you may come across are Kenya trees (Capnela), colt corals or finger leathers (Cladiella), colt corals or cauliflower colt corals (Klyxum), and nepthea or cauliflower corals (Nepthea).

These corals is very difficult to tell apart as undeveloped frag pieces. As you can also see, their names are very confusing, which can make identifying your leather very difficult even as fully grown corals.

What Do They Look Like?

Toadstool corals are one of the most recognizable species of leather coral and one of the easiest corals to identify in general. A Toadstool leather coral has a singular stalk with a large cap. This cap features extended tentacles which can vary in length across species. Toadstool corals are very accurately named after their similar appearance to toadstool mushrooms.

Though toadstool corals are relatively plain in color, only featuring greens, browns, tans, and yellows, they are a popular addition to the reef aquarium because of their impressive sizes. These corals can grow to be almost 2 feet across, though they stay under a foot in the aquarium setting!

Luckily, toadstool corals are very easy to propagate so they are easy to handle if they get too big.

Placement In The Aquarium

Toadstools are very adaptable corals, however, they aren’t necessarily the least demanding. For being such a beginner-friendly coral, toadstools do best under low to moderate lighting with moderate to strong flow requirements.

Many hobbyists find that lighting plays a big role in the colors expressed by your toadstool leather coral. Higher lighting will cause your toadstool leather coral to be brighter and more vibrant. However, these corals are a low-light species and only need about 50-150 PAR¹. They need to either be acclimatized to higher areas in the tank over time or left to grow their stalk naturally.

Keep in mind that these corals can get huge and will block out light from other corals below. While they is placed at all levels of the aquarium, it takes some planning to make sure that you don’t lose a big chunk of real estate in your reef aquarium.

Toadstool corals also need moderate to high flow., flow can never be too strong as the coral will adapt and strengthen its stalk; of course, move the coral if it is being bent over by the current. On the other hand, flow is too low.

Shedding

Leather corals are unique as they have the ability to shed. This happens about once every one to two months and is a natural part of how they keep algae and waste off of them. When your toadstool coral is getting ready to shed, you might notice that it changes colors and has its tentacles retracted for a couple of days.

Eventually, you will see a thin shiny layer form on top of your toadstool coral. Over the next few days, this layer will be shed; this shed can get stuck on other rocks and corals in the tank, but it is not harmful. Once done shedding, your toadstool coral will emerge brighter and fuller than before.

In order to make sheds easy for your toadstool leather coral, it is best to keep it under moderate to high flow.

While shedding is a natural process to keep algae and waste from building up on your coral, it can also be a sign that something is wrong in the water column. Toadstool leather corals are notoriously temperamental with some hobbyists having corals that refuse to open on weeks on end.

For the most part, this isn’t a concern if water parameters are stable and all other livestock is doing well. Expect your leather coral to shed towards the end of this ‘dormant’ period.

Temperament In The Aquarium

For being such a large coral, these corals are very peaceful and almost harmless to other species. There are two main concerns you might have if planning on getting a toadstool coral.

Space

These corals get huge and their growth is unpredictable. Their stalk does not take up much space on the rockwork, but their cap can spread out several inches.

The direction of their growth also largely depends on the water flow and light, so they can take on weird shapes that you might not have allowed for. In general, it’s best to place toadstool corals first and allow some time for them to grow before adding more corals below them.

Luckily, these corals do not have sweeper tentacles and can’t sting, so that is not a concern.

Toxicity

Some species of toadstool coral are toxic and can engage in chemical warfare. This might sound scary, and the effects can devastate a tank, but there are ways to be prepared should this happen.

, toadstool leather corals release their toxins under stress and or if they’re dying. If this happens, you will see other corals also start to rot, shed, or die. For this reason, it is important to remove melting leather corals from the tank as soon as they are noticed; it is possible to frag dying corals if healthy areas still remain.

Once the problem coral has been removed, add activated carbon to remove organic impurities (toxins) from the water and perform large water changes over the next few days. If possible, the remaining corals should also be removed from the reef aquarium and moved into quarantine until the tank is ready again.

Care And Maintenance

Otherwise, toadstool coral care is easy and straightforward. These corals check all the boxes of growing quickly, bringing movement to the tank, and being easy to keep.

There are many different species and varieties of toadstool leather coral, which can bring some difficulty to more advanced hobbyists if preferred. For example, the Fiji yellow coral (Sarcophyton elegans) is one of the hardest species to keep as it requires high light and high water flow to keep its yellow frilled appearance fully vibrant.

Water Parameters And Dosing

Toadstool corals do not need any special water parameters. As a soft coral, they do not need to build a calcium carbonate skeleton so they do not heavily rely on many nutrients to grow like large polyp stony corals (LPS) or small polyp stony corals (SPS).

That being said, toadstool corals need average reef conditions with available nitrates and phosphates. Too often, hobbyists strive for perfect parameters with 0 ppm across the board. Though this might seem like the perfect system, limited nutrients are actually a sign of an unhealthy tank.

Instead, nutrients should be available for coral growth. If keeping only soft corals, these nutrients do not need to be dosed and are introduced naturally into the tank through fish waste, food, and other debris. However, if keeping larger LPS or SPS, then it is recommended to dose those nutrients that are being used for growth.

Feeding

These corals do not need to be fed and will grow quickly enough on their own. In fact, these corals are actually too slow to be fed effectively; their tentacles are very slow to retract so food has the chance to be swept away or eaten by something else in the meantime.

If you are really wanting to feed your toadstool leather coral, then small planktonic foods and specific coral foods, like coral powders, Phytoplanton, and pellets, is given once or twice a week.

What Are Good Tankmates?

Toadstool corals is kept with nearly all reef safe fish and invertebrates. It should be noted that toadstools with long tentacles may be mistaken as an anemone by clownfish. Unlike other anemone-lookalikes that retract when hosted, like Euphyllia, toadstools are better at withstanding annoyances from tankmates and will stay expanded.

In fact, I have personally had hermit crabs crawl all over the tops of toadstools. Though the coral retracted when touched in that one location, it left its other tentacles open and was quick to extend to full size once the hermit crab left.

Still, more coral-hungry fish and invertebrates should be avoided. Anything with teeth or pincers is capable of cutting through the soft flesh of a leather coral, which can lead to toxin release in extreme cases.

Fragging

Toadstool corals are one of the easiest corals to frag but is a little intimidating due to their size and the possibility of toxin release. There is little reason to worry though as long as all tools and equipment are laid out ahead of time.

First, you will need to decide if you want to frag the toadstool coral still inside the main display or if it is possible to remove it and frag it in another tank or bucket. Sometimes the coral is too large or too integrated to remove from the tank, in which case you will need to frag it directly in the aquarium. Here is a good video on how to frag a toadstool coral by How To Reef. I’ll have some details below if you want to keep reading along.

To frag a toadstool that is still in the aquarium, simply use a scissor or a razor blade to cut pieces from the top. Be sure to avoid the stem as the parent toadstool will use this to grow a new cap. Remove the pieces of frag. It is strongly recommended to run activated carbon and perform larger water changes the following days to remove any possible toxins.

Many hobbyists like to trim their toadstool frag pieces more uniformly in order to get a more symmetrical appearance once the coral grows; this is not required, but simply trim the pieces into squares and discard or frag the remaining scraps.

In order to attach the frag to a frag plug or a piece of rock, you may use superglue (cyanoacrylate) or rubber bands. Superglue isn’t as effective with toadstools as these frags may shed several times before attaching to the given surface. In this case, be prepared that some frags may fall off before fully attaching.

A more secure way to attach your toadstool frag is by using a rubber band. Simply wrap the rubber band around the frag and the rock/frag plug. Make sure that the pressure isn’t too tight as this can cause the frag to split apart.

Once everything is done, simply dip the frag in fresh saltwater and/or a coral dip to make sure that no toxins are released back into the display aquarium and to help with recovery.

Why Won’t Your Coral Open?

As mentioned before, toadstools are notoriously temperamental and have been known to close for weeks on end without any signs of improvement. But how long is too long and when should you start to be concerned?

As mentioned before, toadstools are very hardy. However, this does not mean they will thrive in less-than-ideal conditions. Instead, they can take a long time to acclimatize to changed conditions. For example, a toadstool introduced to a new aquarium may take several weeks to fully open up even if water parameters are ideal.

A closed toadstool leather coral can also be a sign of poor water quality, though other fish and corals will likely show signs of unhappiness first. Another reason is that your coral is going to shed, whether it be because of stress or because it needs to clean itself. If you notice other corals closing up during this time as well, it would be best to test water parameters.

Lastly, a closed toadstool is a sign of brown jelly disease. These corals bruise very easily, which can invite infection, namely brown jelly disease. In which case, it is best to remove the affected coral and treat it vigorously as this is highly contagious.

Closing Thoughts

The toadstool coral is a large, impressive coral that doesn’t require much extra care. Not only are toadstool leather corals easy to care for, but they’re also very affordable, quick to grow, and is fragged easily. These corals might not be the showiest in terms of color, but their extended tentacles can bring movement to the beginner or advanced reef aquarium setup.

Origins And Habitat

Mushroom corals are found throughout most temperate to tropical marine ecosystems. These corals do not need much light and thrive in low flow environments. Most notably, they is found in Australia, Tonga, Indonesia, with some of the most popular species originating from the Caribbean, namely from the coasts of Florida.

Mushroom corals, or mushroom anemones, can spread very quickly and are often found in large colonies, covering rocks and other structures, including other corals.

Morphology And Common Names

The Corallimorpharia Order¹ is a large taxonomic category containing nearly 50 species. However, most coral species in the reef aquarium trade belong to the Actinodiscus/Discosoma, Rhodactis, and Ricordea genera, which are collectively referred to as mushroom corals.

The mushroom coral is a soft coral, which means that it does not produce a hard calcium carbonate skeleton like large polyp stony corals (LPS) or small polyp stony corals (SPS). As we’ll see later, this makes for easy propagation of the coral.

Interestingly, members of the Corallimorpharia Order are very similar in morphology to SPS (Scleractinia Order), though this is difficult to see without looking at polyp segmentation. Instead, to most of us, these corals resemble the dome-shaped top and stalk of a terrestrial mushroom, earning them their most common name.

While members of Actinodiscus/Discosoma, Rhodactis, and Ricordea are referred to as mushrooms, many mushroom corals have been given specific names with more rare and expensive variations being assigned brand names.

For example, members of Actinodiscus/Discosoma are named after their colors, like red and blue mushroom corals. Some types of Rhodactis may be named after their color combinations as well, but this genus also contains ‘bounce’ mushroom coral variations.

Ricordea species are simply called ricordeas most of the time due to their unique longer-tentacle appearance and can only be classified into Ricordea florida or R. Yuma:

• R. Florida has a small mouth that is not surrounded by tentacles. The tentacles on the rest of the polyp are random in size and placement. Sometimes these tentacles will have orderly color distribution, but this may be random as well.
• R. Yuma has tentacles surrounding the mouth and is much more colorful comparatively. Their structure follows more order and has alternating small and large tentacles as you move to the outside of the polyp.

Other Types Of Mushroom

There are several other species that are present in the reef aquarium hobby, but more uncommon to find in your average hobbyist’s tank.

This includes members of Amplexidiscus and Paracorynactis which is very aggressive eaters.

What Do They Look Like?

Most mushroom anemones are easy to identify, though some have been modified in appearance so that they might resemble other corals at first glance.

These are a few ways you can tell species of mushroom coral apart. Here are several different types:

Disco Mushrooms

Actinodiscus/Discosoma (pictured above) is one of the easiest and hardiest genera of mushroom coral. These corals are simple in appearance with a circular disk and a mouth in the middle and lay flatly against the surface; these disc anemones has a bumpy texture. Actinodiscus/Discosoma spp. grow a few across in diameter and are most commonly found in solid reds, blues, and greens.

Rhodactis Mushroom Corals

Rhodactis contains some of the more desirable morphs of mushroom coral, like the bounce coral. However, most species of Rhodactis are slightly more ornate than Actinodiscus/Discosoma species and have a pilled or frilly characteristic. They are two or more colors with nearly all combinations and gradients available. These corals can range greatly in size and may stay under one inch or grow close to two feet like elephant ear mushroom corals.

Ricordeas

Ricordea has become very popular in recent years, specifically for biotope setups. As mentioned before, there are only two species of Ricordea. In general, ricordea mushrooms are much different from the previous two genera and is told apart even if interspecies differences is similar. These ricordea shrooms come in a variety of bright colors, stay pretty small, and are recognized for their bumpy appearance. The most popular variant is Ricordea florida.

Sadly, most plainer-looking mushrooms, like those from the Actinodiscus/Discosoma genus aren’t kept in the hobby as much anymore due to more desirable morphs and because of how rapidly they can spread across an aquarium.

If you’re looking to quickly fill a rock with color in your reef tank though, these mushroom corals is the perfect addition.

Why Are Bounce Corals So Expensive?

Despite some mushrooms being undesirable, others are extremely favored and go for high prices. In specific, these are bounce mushrooms, like Sunkist Bounce mushrooms and OG Bounce mushrooms, that can go for over $200 and $700 per polyp respectively.

Bounce mushrooms are a modified type of Rhodactis. They are prized for their overgrown tentacles that are often bright colors and patterns. However, it is unknown how these morphs come about, and so they are rarer to come across. This, in addition to the market of assigning brand names, has made these corals some of the most expensive frags in the industry.

While expensive, these mushroom corals don’t require much extra attention than other types of mushrooms Though losing one of these definitely hurts a lot more than a regular $20 polyp!

Placement And Temperament In The Aquarium

Though mushrooms corals greatly in size, shape, and color, their overall requirements are very similar. These corals thrive in reefs with available nutrients as well as in low to moderate reef light and low water flow movement, apart from Ricordea yuma.

The mushroom coral is very forgiving of water parameters, but won’t tolerate being exposed to too much light and high flow conditions. Mushrooms actually have the ability to move around the rock and even completely detach if they do not like their placement. This can lead to some problems, though.

While mushrooms do not have sweeper tentacles that can attack other corals in close proximity, they can actually be pretty aggressive; some hobbyists have even seen their mushrooms win a fight with chalice corals (Pectiniidae Family). If a drifting mushroom coral lands near other corals, there is a chance that it will start to attack.

Because of this, it is also not a good idea to mix different species from different genera together as they will most likely damage each other. Some hobbyists have had success keeping similar mushroom corals together, but this is still a risk.

The main problem with mushroom coral placement is that they cannot be glued to one place. These corals excrete tons of mucus that prevent the glue from sticking and allow them to slip right out of the hold. Instead, a mushroom coral polyp needs to attach itself to another surface that you can then move–though, your coral might have other plans.

This is done by placing the coral under a permeable container or netting with pieces of rock or frag plugs. Within a few days, the mushroom coral should have attached itself. You may then move your coral to other places of the display, in low light and low water flow.

Otherwise, if you have no other corals in the aquarium, then you can also let your mushroom coral loose in your main display and let it find its own preferred location. Of course, this risks your coral getting stuck in the back of the tank away from light, which could kill the coral.

Care And Maintenance

Once your mushroom has settled, these corals are some of the easiest to take care of and to propagate. As mentioned before, most mushroom corals need the same tank conditions and maintenance besides Ricordea yuma.

General Water Parameters

Mushrooms do not have any specific water parameter needs. Because they are soft corals, they rarely depend on calcium or magnesium due to their lack of skeleton; this is also true for alkalinity, though alkalinity levels should remain constant.

Unless keeping other nutrient-demanding corals, dosing is not necessary. Before you know it, you will probably reach a point where your mushroom population gets out of hand and you will have to remove some.

Otherwise, mushroom corals can adapt to most water parameters as long as they are in the standard range recommended for a reef tank. Of all parameters, these corals will especially appreciate nitrates as too clean of an aquarium can starve the coral in the long run. Mushroom corals can safely be added to new tanks that might fluctuate more in water quality.

In fact, many hobbyists use mushrooms as a warning coral. While most mushroom corals can adapt to changes in conditions, they will shrivel up and excrete mucus when they are stressed. This is a good indicator that something is majorly wrong in the tank before fish and invertebrates start being affected as well.

Feeding

Feeding your mushroom coral is not necessary. In some cases, feedings won’t show any results and excess nutrients are introduced into the tank.

However, some types of mushroom corals is very eager to eat and will enjoy smaller foods. Still, it isn’t recommended to feed more than two times a week to avoid excess waste and to give your coral time to digest.

Ricordea spp. care

Some hobbyists have difficulty keeping ricordeas happy in their tank, specifically R. Yuma. There are a few reasons why your ricordeas aren’t doing well in your aquarium and it starts with importation.

Because ricordeas is found close offshore of Florida, there are large populations of wild-caught mushrooms available for sale. This means that all the hardiness that aquaculture brings with other mushrooms has not been evolved by this genus. This can make ricordeas more demanding when it comes to flow, lighting, and stability.

Ricordeas seem to do best under moderate water movement and moderate light with a good source of nutrients available. It is also important to make sure that your mushrooms are healthy when introducing them into your display as wild-caught corals can bring disease and pests into the tank.

However, if you’ve fixed placement and lighting conditions and your ricordeas are still melting, there is not much else you can do. Some aquariums just can’t support some corals no matter how much we try. The best thing to try is finding an alternative or setting up another aquarium completely with ricordea in mind.

What Are Good Tankmates?

Mushroom corals is kept with a variety of reef-safe fish and invertebrates. Ricordea species are a favorite for biotope setups with macroalgae and other soft corals with endemic fish species, though they is kept in all other reef setups as well. The way mushrooms grow and their size make them ideal for nano reef tanks.

The main problem you will want to look out for is if your mushroom seems to be closed the better majority of the time. This is a sign that something in your display is walking over it or stinging it. For the most part, though, mushroom corals are pretty resilient and will learn goby fish or snail habits and will stop closing up at the first touch.

Of course, fish and invertebrates that are not reef-safe should never be placed with coral. This is especially true as mushrooms can excrete a lot of mucus that can get caught around the tank.

How To Frag

Propagating mushroom corals is easy and is necessary once colonies start overcrowing rocks and other corals. These corals have a unique feature that allows them to regenerate from a small piece of flesh. First, we need to understand how mushrooms reproduce on their own.

Mushroom corals largely undergo asexual reproduction in the aquarium. However, how they reproduce is dependent on the species of coral. These are two ways that you may see your mushrooms splitting:

1. Mushroom corals have the ability to split into two. Your mushroom coral may start to form an odd figure-8 shape where there have noticeably short and long sides of their polyp. During this time, you might even be able to see two independent mouths forming in the center. Eventually, these two sides will split into two new polyps.
2. Mushrooms can also leave a piece of themselves behind, which will then grow into a whole new polyp; this is known as pedal laceration. In cases like this, you will see your coral stretching in one direction with one section of the foot taut. Eventually, the main foot will detach from this part and the piece will develop a recognizable polyp within a few weeks.

It should be noted that mushrooms that are looking to detach from rocks and move to a new place may also look like #2 and can leave behind a piece in the process.

When fragging, we try to emulate natural splitting. There are two main ways that mushroom corals is fragged:

1. Take a mushroom polyp that is attached to a small piece of rock. Use a scalpel to divide the coral down the middle near the mouth as it would divide on its own. Then, take a bone cutter and split the rock in half; this helps with the issue of a mobile frag and keeps the two pieces from rejoining.
2. If you’re dealing with a mushroom that isn’t attached to a surface, then you will need another method similar to when you first introduced the coral into your tank. Simply cut the mushroom once down the middle again, or as many times as you would like. Then, use a controlled environment with low flow or use a permeable container that gives time for the frag to attach to a new surface.

Once the coral has attached itself and fully healed, it is time to move the mushroom to the desired place in the tank or give it away to another hobbyist.

Mushrooms are extremely forgiving of being fragged and can survive multiple slicings. It is not necessary to dip them before being placed back into the display, but iodine or another coral dip may be used for extra security. If you would like a more visual guide, here is a nice video from Reef Life Aquatics.

Controlling Coral Growth

Though mushrooms can fill empty spaces in the aquarium, they can also quickly start to get out of hand. Because of their ability to regrow from a small piece, it is very difficult to control populations once established.

If your mushrooms are confined to one section then one of the easiest, but definitely not one of the most convenient, ways to fix this is by removing the whole rock from the display. Sadly, this will remove some of the beneficial bacteria from your tank but it ensures that the mushrooms are gone for good.

If you have mushrooms growing on multiple surfaces throughout the display, then this will be much more difficult and a longer struggle. This method involves removing the mushrooms one by one by hand. Simply keep removing any mushrooms you see and try to scrape away as much of the flesh as possible.

If you’re comfortable with bringing in some chemical options, then anything that is meant to kill Aiptasia will also work on a mushroom coral, like Aiptasia-X. You will need to be careful as these solutions can also damage other nearby corals.

One of the last ways to deal with explosive mushroom growth is by reducing the number of available nutrients in the water column. However, this is tricky and can have ill effects on the rest of your reef.

Mushroom corals thrive in dirtier water. Once those nutrients are taken away, growth should hypothetically decrease along with them. This method is only recommended for experts in water chemistry.

Closing Thoughts

Mushrooms are an understated coral that can bring color to low flow areas of the display with low light conditions. With such a large variety of mushrooms to choose from, there are colors and patterns for everyone.

These corals can spread very quickly, so population control will be needed to keep numbers in check or to regularly frag new pieces. Otherwise, they will continue to grow wherever they can when nutrients are available.
