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 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.

An Overview On The Montipora Coral

Classification

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.

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.

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 :).

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.

Small polyp stony (SPS) corals are the end goal for many reef hobbyists. In the wild, these corals, like the impressive staghorn coral, define marine ecosystems and house a plethora of life on the reef. In the aquarium, they can bring the same color and depth to the tops of rockwork that other large polyp stony (LPS) corals and soft corals cannot.

However, SPS corals are regarded as the most challenging species of coral to keep in the home aquarium setting. While it is true that they are more difficult than other types of common coral, they are not completely out of reach for more serious hobbyists.

What Is The Difference Between Other Corals?

SPS corals are easy to identify. They completely lack the fleshy, large colony quality that LPS and soft corals have. Instead, SPS corals have a hard branched or plated appearance with individual polyps.

In the reef aquarium hobby, SPS are to be the most difficult species to keep, with LPS being for intermediate hobbyists, and soft corals being best for beginners. Apart from this, all three have very different anatomy and physiology.

SPS corals, also known as hard corals, are responsible for building the natural reef. These animals excrete calcium carbonate skeletons that make structures for fish and invertebrates to find shelter; symbiotic zooxanthellae are also housed in these skeletons and complete photosynthesis which feeds the coral.

Taxonomically, SPS corals belong to the Scleractinia order¹. From there, they are members of the Hexocorallia subclass which means that their polyp symmetry is divisible by six. Such as they are named, they have very small polyps on the outside of their flesh-covered calcium carbonate skeleton.

The calcium carbonate skeleton of SPS corals is built to withstand the battering from rough waves at the top of the reef where these corals are found. This also allows them to receive the most direct sunlight as their branches can grow for optimal exposure. This translates to a reef tank setting with the need for higher lighting and increased water flow.

Soft and LPS Corals

On the other hand, soft corals and LPS is entirely fleshy, have a calcium carbonate skeleton, or contain sclerites, meaning they contain small pieces of hard internal structure; the main feature of soft corals and LPS corals though, is their very obvious polyps which can extend to impressive sizes.

Some LPS corals do have a calcium carbonate skeleton, however, the polyps extend outwards and don’t cover all parts of the structure such as they do for SPS. Some soft corals may contain sclerites but are much less structured than LPS overall.

Both LPS and soft corals are found lower down on the reef where the water current is not as strong and lighting is indirect. This translates into the aquarium with low to moderate lighting and moderate flow requirements for most species within these two categories.

Keeping Them In The Aquarium

SPS corals are notoriously known for being difficult to keep. But are they actually that much more demanding than other corals? Yes and no.

Yes, SPS corals are much more demanding than soft corals and LPS corals, but this doesn’t necessarily mean that they’re all more difficult. The main difference is the setup and the maintenance: SPS corals need a high-tech setup and stable conditions while LPS corals and soft corals can adapt to less optimal conditions.

A high-tech setup starts with good lighting, water flow, and filtration. SPS corals are some of the most light-demanding corals, and a good light fixture is necessary. This light needs to have a fully programmable spectrum, intensities, and photoperiod at the very least. The EcoTech Radion is a great example of an LED designed for the demands of an SPS tank.

Water flow is almost, if not more, important than lighting. Water circulation keeps corals fed and prevents algae from taking over. Many SPS corals grow in tight colonies, which can cause dead zones in the densest parts. Water flow needs to be random in order to keep fresh water pushing past all areas of the colony at all times.

Though some reef aquarium hobbyists run SPS-dominant reefs with simple filtration, it is also a must to have a sump system. Sumps allow for additional room for beneficial bacteria to grow, increased nutrient export, and adequate aeration. All of these factors play into a more stable system overall.

Stability is arguably the most difficult part of keeping SPS. These corals are notorious for bleaching and eventually dying when conditions change too quickly. All major water parameters, along with alkalinity, calcium, magnesium, pH, salinity, and temperature all need to be constant for success.

Many hobbyists regulate these parameters with digital monitors, auto top-offs, and doser pumps, even Calcium reactors for full high end systems. These all get get very expensive over time. However, if you’re willing to spend the money upfront for a top-of-the-line SPS system, then there is a good chance that you will succeed in keeping these corals. Of course, you may do everything right but still have problems.

Water Parameters

That being said, what are the perfect water parameters for an SPS reef tank?

As always, these values can differ between tanks and hobbyists have had luck below and above the listed ranges; if your water parameters and tank conditions do not match these but your corals are healthy, do not attempt to change your system just to meet ‘ideal’ numbers.

In general, though, these are the accepted ranges for keeping SPS corals:

• Lighting – High (200+ PAR)
• Flow Rate – High
• Temperature Range – 76-82 F
• pH Range – 8.0-8.4
• Salinity – 1.025 and 35 PPT 
• Alkalinity – 8 dKH
• Calcium Level – 350-450 PPM
• Magnesium Level – 1200-1350 in PPM

Note that many hobbyists keep SPS corals in lighting conditions well over 200 PAR, though this is to be the bare minimum for attempting them at all.

Temperament In The Aquarium

One of the good things about SPS is that they are not very aggressive corals. This allows multiple species to be housed very closely together without too many problems; this does not mean that they will not try to sting each other though, so it is always best to be cautious and to trim any corals that grow too close together.

The main problem with SPS aggression is with other corals. LPS corals with long sweeper tentacles are very capable of stinging sessile SPS, which can quickly cause tissue loss and other damage. To prevent this, simply keep LPS away from SPS, possibly at another level of the tank.

Though SPS is able to regrow once the problem has been addressed, this still gives time for algae to takeover exposed skeleton which can impact the overall health of the coral.

Common Types (Different Species)

SPS corals make up the ‘ideal reef’ that many envision when they think about a coral reef in the ocean; SPS are branching corals that give reefs their signature appearance. However, different species of SPS corals is difficult to tell apart to the untrained eye. This is due to a few reasons.

One, SPS are sold as small frags, which can make exact identification nearly impossible with such a small sample. Secondly, species of SPS can vary greatly in color and shape across the genus; as we’ll see, Montipora especially can come in several formations.

It should also be said that SPS-keeping is another level of the aquarium hobby. You will often come across corals that you have never seen before and might never see again. In general, it is best to know the general attributes of each major SPS genus and try to apply them to what you see.

Montipora

• Scientific Name: Montipora spp.
• Difficulty Level: Easy-Moderate
• Temperament: Not aggressive
• PAR Requirements: Moderate (150 PAR)
• Flow Requirements: Moderate-High
• Placement: Middle, High
• Origin: Indo-Pacific

Montipora is a genus of SPS corals with very diverse members. These corals can come in branching, plating, and encrusting varieties in almost all colors. They are not overly demanding in regards to being an SPS coral, but they do require high lighting, good flow, and stable water parameters just as the other, more advanced corals on this list do.

The most common types of Montipora to come across are Montipora digitata and plating Montipora.

Montipora Varieties

Montipora digitata is a branching variety of Montipora. The two most common colors are orange (‘Forest Fire Montipora digitata‘) and green (‘Green Montipora digitata‘); these corals have been modified to express the best colors and may be assigned a designer name.

Montipora digitata have thicker branches that sometimes grow together to form antler-like structures. Their polyps are very concentrated and have a soft appearance. The tips of these branches will be bare and white where new skeleton growth is forming.

In comparison, plating varieties, like Green Montipora digitata, grow outwards in large circular disks. Similarly, the tips of these plates will be white with new growth.

All varieties of Montipora is attractive to most hobbyists as they’re one of the easiest and fastest species of SPS to keep.

Pocilloporidae Family

• Scientific Name: Pocillopora spp., Seriatopora spp., and Stylophora spp.
• Difficulty Level: Easy-Moderate
• Temperament: Not aggressive
• PAR Requirements: Moderate (200+ PAR)
• Flow Requirements: High
• Placement: Middle, High
• Origin: Indo-Pacific

Members of the Pocilloporidae family are largely known as bird’s nest corals due to their interweaving branching growth. They come in many colors and are said to be even easier to keep than Montipora, but still require SPS growing conditions.

There are three genera of bird’s nest coral commonly found in the aquarium hobby: Pocillopora, Seriatopora, and Stylophora.

Pocillopora

Pocillopora Coral

The Pocillopora is a great first time SPS coral that is forgiving on parameters. Peaceful and a moderate grower

Pocillopora have thick, stubby branches. They have a moderately fuzzy appearance and are most commonly found in greens and purples.

Due to their thick branching, these corals do best with higher rates of water flow.

Stylophora

Stylophora are very similar to Pocillopora. In fact, it is only possible to tell these two corals apart by looking at a full colony.

Stylophora also have rounded branches with moderately fuzzy polyps. However, the overall appearance of the colony be more orderly and uniform than that of Pocillopora.

Seriatopora

Seriatopora are largely known as the true bird’s nest corals of this family as they have pointed tips and very thin branches that create an intricate twig-like cluster of coral. These corals are also most commonly found in pinks, greens, and purple and green combinations; their polyps are much more spread apart than the other related corals.

Seriatopora are very delicate and need to be handled with care. This can make fragging them very easy but can also make transportation quite difficult for larger colonies.

• Scientific Name: Acropora spp.
• Difficulty Level: Hard
• Temperament: Not aggressive
• PAR Requirements: Moderate (200+ PAR)
• Flow Requirements: High
• Placement: Middle, High
• Origin: Indo-Pacific with some species in the Caribbean

Acropora are the end goal of many intermediate and advanced reefers. These corals are seen as some of the most difficult, yet most rewarding species in all of the hobby. There are many types of Acropora to choose from that come in nearly all colors, including more exclusive designer names.

Even though there are many different kinds of Acropora, they are still relatively easy to identify. These corals branch and have very identifiable polyps; each polyp has its own little tube that gives the coral a bumpy appearance. The actual polyps is long and stringy or short and flat.

Acropora are the most difficult because they are easily affected by changes in water parameters. They also demand the most light and water flow out of all these species.

Closing Thoughts

SPS corals are thought to be some of the hardest, yet some of the most rewarding species of coral available in the aquarium hobby. Though this is true, their actual requirements aren’t as challenging as you might think. Instead, it’s their need for stability and consistency that can make their care extra difficult.

Luckily, there are a few easier species, like Montipora spp. And members from the Pocilloporidae family, that can make the transition from LPS corals and soft corals to Acropora a little less intimidating.

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.

Kills Aiptasia

Aiptasia-X

A great solution for target elimination of Aiptasia in a reef tank.

Click For Best Price Buy On Amazon

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)

Great Against Aiptasia

Peppermint Shrimp

These little shrimp are the most common livestock treatment for Aiptasia. Available as tank raised and reef safe.

Click For Best Price

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!

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.

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

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.

Species Overview

Classification

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.

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.
