Nerite Snails are the best algae eaters in freshwater. They eat every type of algae, they do not reproduce in freshwater, and they work nonstop. The downside is the white eggs they lay everywhere.

Nerites are perfect algae eaters with one flaw. Those white eggs on every surface in your tank.

Nerite snails are probably my most-recommended algae-eating invertebrate, and the reason is simple: they’re effective without the usual downsides. They won’t breed out of control in your freshwater tank. Their larvae require saltwater to develop. They won’t touch your live plants, and they come in shell patterns that are genuinely attractive. Zebra and tiger nerites are the most common, but horned nerites and olive nerites are worth tracking down too. Honest caveat: they do leave white egg casings on hard surfaces, which some people find irritating. Here’s the full care guide.

Species Overview

Classification

Introduction

Nerite snails are an anomaly in the aquarium hobby. They are one of the few species that is kept in entirely freshwater or saltwater conditions as well as mixed salinities in between. Nerites are also one of the best algae-eating species of snail available, making them one of the most popular–and one of the more expensive–types of aquarium snail.

This article will focus only on freshwater nerite snails and their care requirements.

Nerite snails are hardy, but they is sensitive to ammonia and nitrite in the water column, which means that they need a more established setup.

Are They Good For Your Freshwater Tank?

A nerite snail is one of the best additions you can make to your freshwater aquarium, especially a planted aquarium! These snails have a serious appetite for algae.

Nerite snails are proficient algae eaters. They will eat most species of algae, but are most efficient at cleaning up soft types, like hair algae, green spot algae, and green slime algae. They use their modified tongue, called a radula, covered in tiny teeth that help scrape away microflora.

As we’ll see, nerite snails are largely herbivores. They won’t necessarily clean detritus from fish and other organisms in the tank, but they’ll keep plant surfaces and the sides of the aquarium algae-free.

How To Identify

Snails is hard to tell apart. And the problem is that not all snails are created equally.

Some snails clean algae better while others take care of detritus and even other snails. Freshwater snails can also be expensive, so you definitely want to take the time to understand what the species of snail you want looks like.

Nerite snails are a larger species of snail. There are many species of aquarium snail that belong to the Neritina genus, each with its own identifying characteristics.

No matter the species though, nerite snails grow to be about 1-2 inches on average. These snails have an unbalanced appearance to them, with a rounded shell that tilts into a whorl on the right side. The body of the snail ranges in color from tan to dark brown. Unlike other snails, the body of the snail is concealed completely under the shell even when moving.

Unfortunately, there is no way to tell a male nerite snail apart from a female. Another big difference from other snails is that nerite snails are not hermaphrodites. This, in addition to their need for brackish water conditions, makes breeding nerite snails very difficult for the average hobbyist.

Origin and Habitat

Nerite snails have a wide distribution. Most species originate from the coastal waters of Africa but a few are found in the Caribbean or on the margins of the Pacific Ocean. Nerite snails are intertidal and regularly move between the nearby ocean and freshwater rivers and inlets; it is believed that they prefer brackish water conditions most of all.

This crossover between ecosystems leaves nerite snails with a large assortment of foods to eat. They will regularly be seen munching away at algae on rocks and other structures but will travel across the open sandbed as they grow and reproduce.

Care

In the aquarium, nerite snails are relatively hardy. They aren’t as hardy as something like the bladder snail (Physella acuta) that can survive polluted waters, but nerites can definitely withstand some beginner’s mistakes. Nerite snails are most sensitive to changes in ammonia and nitrite.

Otherwise, nerite snails are easy to care for in the freshwater aquarium. If there are enough algae to graze on, they will live for a relatively long time.

Tank Size

Freshwater snails are often limited in tank size due to their high reproductive rates. Nerite snails do not breed in freshwater, so they are one of the better choices for smaller aquariums.

The general rule for nerite snails is 1 snail for every 5 gallons of water; this means that 1 snail will comfortably fit in a 5-gallon betta tank or other planted aquarium. For larger tanks, the number of nerite snails will be limited by bioload. As these snails don’t reproduce in freshwater, there is no way to unknowingly overstock them as long as there is adequate biological filtration.

Aquarium Setup

Nerite snails is kept in most freshwater tank setups. They excel in planted aquariums with lots of natural algae and microflora that they can graze on, but they’re also suitable for unplanted tanks as long as their dietary needs are met.

Nerite snails aren’t shy, but they’re mostly nocturnal. In fact, nerite snails can sleep for days at a time, only becoming active in short spurts. This means that they prefer to stay somewhere hidden to stay out of reach of predators. Driftwood, plants, rocks, and other aquarium structures can make perfect nooks and crannies for your snail to rest.

Because they’re nocturnal, nerite snails will also prefer dim lighting. The aquarium light may be dimmed or floating live plants and other large plant species may be used to create pockets of shade and refuge throughout the aquarium.

Nerite snails are also intertidal, which means that they regularly move between the water and moist, but not submersed, surfaces. It is not unusual to find a nerite snail at or above the waterline of the tank. They often find their way into the filter and might even crawl onto the outside of the glass. Because of this, it’s strongly recommended to use a fitted aquarium cover.

Water Parameters

Nerite snails need 0 ppm ammonia and 0 ppm nitrite. Any traces of ammonia or nitrite could prove to be deadly to your snails. Like other invertebrates, they also cannot tolerate copper.

Otherwise, these freshwater snails do not need specific water parameters. They are largely tropical species that need a warm water temperature. With proper acclimation, they is kept at slightly cooler or warmer temperatures. Freshwater nerite snails also prefer a near-neutral water pH between 6.5-8.0 but can adapt to more acidic conditions.

Preferred water parameters largely depend on the conditions the snails are originally being kept. Remember, these are brackish water snails that can tolerate higher salinities and subsequent higher pH levels. Brackish water salinity measures at about 1.005 to 1.010 while full saltwater is 1.023 to 1.025.

Like other snails, nerite snails grow with their shells. They use calcium and other minerals available in the water column to continue growing and maintaining their shells. While these minerals are readily available with good source water, they need to be supplemented every now and then through their diet or with calcium blocks.

An injured or nutrient-deficient nerite snail may have noticeable white scrapes and scratches across its shell. These injuries will continue to progress if calcium isn’t made available for repairs.

Filtration and Aeration

Even though nerite snails only grow to be about an inch or two, they can still create a significant amount of bioload that can affect the efficiency of the filtration being used. That being said, they have also been successfully kept in Walstad-method aquariums that rely solely on the biological filtration provided by live plants and bacteria without any additional equipment.

If the overall bioload of the aquarium is on the higher side, then it is beneficial to add aeration for better oxygenation and gas exchange.

Lighting

Remember, nerite snails are nocturnal and have an interesting sleep cycle. Lighting intensity doesn’t matter too much, but these snails definitely need a discernible night and day cycle to keep a semi-regular sleep cycle.

Aquatic Plants and Decorations

Nerite snails absolutely love aquatic plants and decorations! But they’re not entirely necessary for the success of the snail.

Nerite snails eat algae that grow on the surfaces of the tank. That means the more surfaces available, the more food your snail has to choose from. They are unlikely to eat healthy live aquarium plants but will help consume any rotting stems or leaves.

Community Tank Mates

As a larger type of snail, nerite snails are among the best community tank snail species. These snails will keep to themselves and won’t disrupt other peaceful species.

This makes nerite snails completely compatible with:

• Tetras
• Guppies
• Gouramis
• Rasboras
• Betta fish

, betta fish is kept with nerite snails. The problem is that nerite snails can fall off the glass, occasionally landing on their back with their body exposed (yes! These snails can flip themselves back over). A curious or hungry betta may pick at the snail while it’s vulnerable, like other larger and more aggressive fish species.

Food and Diet

Nerite snails will feed themselves as long as there is enough algae available in the tank.

There is little need to offer your snails anything additional to eat, though experienced keepers like to feed algae wafers and blanched vegetables, like cucumbers and lettuce; providing fresh vegetables from time to time can help introduce minerals and nutrients that can’t be obtained otherwise.

In the same way, calcium blocks may be added for healthy shells.

Breeding

Breeding nerite snails are extremely difficult for the average hobbyist. This is because it takes several fish tank setups to be successful. In the wild, nerite snails move between freshwater and saltwater. They are most often observed in brackish conditions for reproductive purposes.

Hobbyists seem to have the most breeding success when acclimating or keeping nerite snails in brackish water. When ready, a male and female will breed. The female will lay eggs in a safe area, on the aquarium glass or under a leaf. The nerite snail eggs will hatch after some time into larvae that later develop into recognizable, baby snails.

Nerite snails will not breed in the freshwater aquarium. Female nerite snails may lay their eggs around the aquarium, but they will not hatch. Take this as an indication that your snail is happy and healthy.

4 Types

There are many species of nerite snail, though only a few have made their way into the aquarium hobby. Luckily, there aren’t any big differences between the different types of nerite snails, so you can trust that your aquarium will always get cleaned!

This includes zebra horned nerite snails, zebra nerite snails, tiger nerite snails, and black racer nerite snails.

1. Horned

• Adult Size: 0.5 inches
• Color Pattern: Black and yellow spiral
• Unique Traits: Small spikes that outline the whorl

The zebra horned nerite snail (Clithon corona/diadema), also known as the zebra thorned nerite snail, is one of the most interesting-looking snails out of all freshwater snail species!

These are tiny snails, staying under an inch at full size. Zebra horned nerite snails have beautiful alternating black and yellow stripes, which can help bring a pop of color to the bottom of the fish tank. Their most interesting feature is the tiny spikes that outline the whorl of the shell. These are most likely used in defense against aggressive fish and invertebrates.

2. Zebra

• Adult Size: 1 to 1.5 inches
• Color Pattern: Yellow and black/brown
• Unique Traits: Alternating black and yellow zebra pattern

The zebra nerite snail (Vittina natalensis) is probably the most recognizable species of nerite in the aquarium hobby. These snails are large with very smooth shells. Zebra nerite snails are mostly known for the unique pattern on their shells.

The color of the zebra nerite shell can vary from light yellow to warm orange. Every snail will have a zebra-like pattern with alternating black and yellow stripes that meet at the center of the whorl. Though inexpensive, these snails can bring a clean and expensive aesthetic to freshwater tanks.

3. Tiger

Tiger Nerite Snails

These Nerite Snails will eat algae, are plant safe, and do not reproduce in your aquarium!

• Adult Size: 1 to 1.5 inches
• Color Pattern: Yellow or orange with black patterning
• Unique Traits: Simple, uniform black spot patterning

Often sold alongside related zebra nerite snails, the tiger nerite snail (Neritina semiconca) has a beautiful natural appearance. These snails can vary in color intensity, from light yellows to dark browns. They are most easily identifiable by the flake-shaped black specks that run across the front of the shell and onto the whorl.

4. Black Racer

• Adult Size: 1 to 1.5 inches
• Color Pattern: Black Appearance
• Unique Traits: Dark ebony base color with lighter striations

Not the most popular, the black racer nerite snail (often categorized as Neritina pulligera) is actually one of the most common nerite snail species to come across at local fish stores. These snails are plain in color under poor lighting and appear as dark brown or black shells. However, under the right light, this species of nerite snail can become a spectacle with dark greens and browns with lighter colors (video source).

Compared to the other nerite snail species on this list, the black racer nerite snail grow to a larger adult size.

Is the Nerite Snails Right for You?

Before you add a nerite snails 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. Nerite Snailss 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 nerite snails 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 Nerite Snails Compares to Similar Species

Choosing between similar species is tricky. Here’s how the nerite snails stacks up against some common alternatives.

The nerite snails 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 nerite snails 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 nerite snails needs, it’s hard to beat. If not, there are alternatives worth exploring.

Final Thoughts

There are many types of nerite snails to choose from. Each one has its own colorful appeal, but they are all excellent algae eaters that will help keep freshwater tanks clean without disrupting any other the tank inhabitants.

One of the best aspects of the nerite snail is that they can’t reproduce in pure freshwater. However, they can still carry a high bio load so it’s important to not overstock a tank.

The Honey Gourami is one of the most misunderstood fish in the hobby. I have watched beginners buy them expecting a peaceful, easy community fish, only to deal with aggression, disease, or slow decline within months. After keeping gouramis for over two decades, I know exactly where most people go wrong.

Most gourami problems start with the tank, not the fish.

Gouramis live 4 to 6 years in good conditions. That means consistent water quality, proper tank mates, and an environment that lets them feel secure enough to show their natural behavior.

The right gourami in the right tank is one of the most graceful fish in freshwater. The wrong gourami in the wrong tank is a stressed, aggressive nightmare.

What Most Care Guides Get Wrong About Honey Gourami

The biggest problem with honey gouramis isn’t the fish itself. It’s misidentification at pet stores. What gets sold as a “honey gourami” is frequently a color morph of the dwarf gourami, not Trichogaster chuna at all. Real honey gouramis have a more subtle, golden-amber coloration that’s distinctly different from the bright red-orange “sunset” varieties that are actually dwarf gourami hybrids. I’ve seen this mix-up at every major chain store I’ve visited. The other myth is that they’re shy, boring fish. In a properly set up tank with floating plants and dim lighting, honey gouramis are active, curious, and surprisingly bold.

The Reality of Keeping Honey Gourami

Disease susceptibility is a real issue with commercially bred stock. Dwarf gouramis in particular carry Iridovirus at alarming rates. Even honey gouramis from mass-production facilities arrive stressed and immune-compromised. Buying from a reputable source matters more with gouramis than with almost any other community fish.

Males get territorial. The “peaceful community fish” label on gouramis is misleading. Male gouramis of most species will harass other males, especially in tanks under 30 gallons. One male per tank is the safest approach for most setups.

Surface access is non-negotiable. Gouramis are labyrinth fish. They breathe air from the surface. Strong surface agitation or tall tanks with limited surface area stress them out. Leave the top of the tank calm with floating plants for cover.

Biggest Mistake New Owners Make

Keeping multiple male gouramis in the same tank. One dominant male will relentlessly chase and stress the others. In a community setup, stick with one male and two or three females at most.

Expert Take

I always tell new gourami keepers the same thing. Buy from a breeder, not a chain store. The quality difference in health and coloration is worth the extra cost every single time.

An Overview of Honey Gourami

Classification

What is Honey Gourami?

Honey Gourami, scientifically identified as Trichogaster chuna, is part of the Osphronemidae family from order Anabantiformes.

They are tropical fish known for their deferential behavior, colorful body, and labyrinth organ. This organ helps them breathe dry air and survive in areas where the water is low oxygenated. In aquarium trades or even in the wild, coming across a fish like Honey Gourami is pretty rare.

They enjoy freshwaters and prefer sticking to the middle to upper levels of water. Blending in with other fish species isn’t their thing, they like being solo. They accumulate themselves once they feel nothing would threaten their peace and freedom of swimming around.

Origin and Habitat

They originate from the regions of India, Bangladesh, and Nepal. They were first sighted in 1822 by Francis Buchanan, also known as Francis Hamilton.

The male and female Honey Gourami were mistaken for two different species initially. But with study and close inspection, Francis Buchanan identified them as male and female fish from the same species.

In their natural habitats, you can find thick vegetation throughout and poor water quality. They are naturally intimate with slow-moving water with moderate pH levels and warm water temperatures.

Appearance

Due to some similarities between a Dwarf Gourami and a Honey Gourami, they are often confused. Before planning to buy your intended fish, it is better to understand their appearance differences.

A Honey Gourami features golden-yellow, clay-orange, red, and honey shades. Some of them look silver, gray, and brown, which are mostly female Honey Gouramis. There’s a cool brown-colored band starting from around the eyes and ending at the caudal peduncle.

A Honey Gourami is small, reaching up to only 2.5 inches. While most of them are this size, a few of them were recorded stretching themselves up to 3 inches.

They have 7 fins on them, including a pair of small pectoral fins, a dorsal and anal fin, and a caudal fin. You can also see thread-like pelvic fins attached right below their bodies.

The dorsal fin begins from around the forehead, running down towards the caudal fin. Then there is the anal fin that travels side by side with the dorsal fin on the ventral area. Honey Gouramis have tiny pectoral fins attached to their bodies, with a beautiful and long threadlike fin right below that.

The simplest way to tell apart the difference between the male Honey Gourami and the female Honey Gourami is by looking at their coloration, fins, and sizes.

As with most fish species, the males display brighter shades than the females. The females have silver-colored bodies to pale yellow body coloration. The males, however, are bright yellow or orange.

Almost all males change their color to a brighter shade as growing up or during breeding. Whereas in females, you don’t see any color alterations as compared to males. Apart from this, males have prominent fins, while females get rounded anal and dorsal fins. And the males are also slightly bigger than the females.

But both sexes appear thin from the sides and look large from the middle of their bodies. Also, they have white abdomens, which turn dark in and around the breeding season.

The Difference Between with a Dwarf Gourami

Want a peaceful labyrinth fish for a community tank? Get a honey gourami. Want more color and size? Get a pearl gourami. Avoid dwarf gouramis from chain stores unless you are willing to gamble on Iridovirus.

Because of bad identification, you can often find a Dwarf Gourami labeled and sold as a Honey Gourami in fish stores. Though there are a few similarities between them, one can easily tell them apart.

Honey Gouramis have narrow bodies and they have smaller dorsal and anal fins. A Dwarf Gourami is 4 inches on average, while Honey Gouramis are only 2 inches, making them the smallest fish of their group.

Another major difference is their body coloring. A Honey Gourami looks solid yellow, orange, red, or honey-colored. And a Dwarf Gourami looks red or blue and is paler. Other than that, Honey Gouramis have eyes closer to their mouths and Dwarf Gouramis don’t.

Lifespan

A Honey Gourami lives up to 8 years in captivity. In the wild, due to various reasons, they can’t keep predators and health problems at bay. And this results in shortened lifespans.

To improve the overall quality of life, gauging the right water parameters, as well as preventing them from taking stress, is important.

They thrive in freshwater with a temperature ranging from 74 to 82 F. But, there’s more to their basic requirements that we will discuss in more depth.

Average Size

The Honey Gourami is the shortest member of its family. Their maximum size is only 2.5 inches and, in some rare cases, 3 inches.

Like other freshwater fish, they take almost 2 years to reach their full size. The males are slightly larger than females – almost about an inch.

Care

As a novice, the hardest part is to go make water conditions ideal, the aquarium setup, dietary requirements, and finding compatible tank mates for the fish. Any shortcoming in fulfilling any of this is dangerous for your fish.

Aside from giving a spectrum touch to your aquariums, a Honey Gourami can also withstand slight water condition changes. So instead of fussing over intricate details, you can actually think about starting your journey right away.

In your aquarium, you can replicate natural conditions and provide your Honey Gourami with a solid home. They thrive in warm water temperatures, ranging from 74° F to 82° F.

Because this hardy fish moves in groups, a larger aquarium is necessary for this active fish. Honey Gouramis are familiar with living around thick vegetation, so introduce thick plants to your tank.

Since Honey Gourami appreciates social gatherings and hardly shows any aggression, handling it becomes completely trouble-free for beginners. But, under certain circumstances, the male Honey Gourami is likely to become aggressive to its tank mates and females around.

Unlike other more sensitive freshwater fish, they are not susceptible to serious diseases. But neglect in managing them properly is dangerous. Here are some essential things to consider before housing a Honey Gourami.

Aquarium Setup

The fish Honey Gourami hails from South Asia where the water be slow-moving and warm.

In South Asia, specifically in India, Bangladesh, and Nepal, they inhabit rivers, lakes, and ditches and can also be found throughout flooded areas.

The waters of these fields are slightly acidic and moderate to high in hardness. Also, there are thick plants that work to provide them with shade and hiding spots.

Honey Gouramis flourish in a stress-free environment. So, try to mimic their natural habitat as closely as possible to stem the flow of anxiety.

Gouramis do their best solo or in pairs. If you pair them, make sure you give than a larger tank to curb aggression.

Because Honey Gouramis are active and prefer spending their time exploring their surroundings, jumping out of the aquarium is likely. To ensure their safety, keep a tight lid on the tank.

Tank Size

Since they are quite small, you don’t need to arrange enormous tanks for them. However, they are social fish and do not enjoy living alone. If you want to house only a pair of them, then a 15-gallon tank is ideal. But if want a group of 6 Honey Gouramis living together, go for a 30-gallon tank.

Water Parameters

Their ability to put up with subtle water changes is worth mentioning. But, they do need properly measured water parameters to thrive. Remember that they come from South India where the streams, rivers, and pond waters are warm.

While going over the water conditions, do not heat up the aquarium too much. It should be above 74° F and below 82° F, with water hardness between 4 to 15 KH. The pH levels should be around 6.0 to 8.0. And that’s ideal for them. Make sure ammonia and nitrite levels stay at 0. Keep your nitrates reasonable with under 30PPM being ideal.

Filtration/Aeration

Another key factor that leads up to the overall health maintenance of your Honey Gourami is filtration. Since the fish is small, it doesn’t produce a lot of waste. However, in groups and in planted tanks, there is more waste production to consider that would make a higher quality filter more appropriate.

I recommend using a strong filtration system to keep the water quality up to the mark. You can use a sponge filter or a hang-on-back filter to strain the water thoroughly. Also, regular weekly water changes ( 20-50% depending on the bio-load) will keep your aquarium in a healthy condition.

Honey Gouramis can’t withstand strong water currents. So, make sure any filtration system that you are using doesn’t disturb the water flow.

Lighting

You don’t need any artificial lighting for your Honey Gourami. A moderate amount of natural lighting is enough for the fish and plants.

But to keep a check on their day-to-day activity, you can use Led lights that are not too bright. Bright lights can disturb them and force them to hide in caves or under thick aquarium plants.

Aquatic Plants and Decoration

With staying mostly on the top areas of tanks, a Honey Gourami hardly travels down to the bottom. Therefore, live floating plants are ideal for them.

In the wild, a Honey Gourami uses thick leafy plants as a shelter. And since you want to make them feel at home, I recommend considering live aquarium plants for their tanks.

Unlike other fish species, you will never see your Honey Gourami attacking a plant. They might nip at the plants, but only because of curiosity.

They need plants to use as a hideout. Also, they build their bubble nests into plants, so make sure they have a good amount of floating plants in the tank.

Even though a Honey Gourami uses its labyrinth organ to breathe air if there is not enough of oxygen, other fish prone to low oxygen levels can’t do that.

Apart from filtering their water using strong filtering systems, live plants can help filter our excess nutrients like nitrates from their tanks.

In their natural habitat, Honey Gouramis travel to the surface areas of water to draw breath. While setting up their tank, don’t cover the surface completely with plants.

Some great recommendations for underwater and floating plants are:

• Wisteria
• Anacharis
• Java Fern
• Anubias
• Hornwort
• Java Moss

Pro Tip: Avoid using too many plants and manufactured caves. This will result in preventing you from keeping a check on them.

Tank Maintenance

Cleaning the tank of your honey Gourami is totally hassle-free. These small fish feature so many irresistible characteristics that make you fall in love with them.

Because the fish prefers to live in a thickly planted aquarium in groups, cleaning their tank is more than necessary. Here are some simple steps to get you started.

How to clean the tank?

1. Start off with cleaning the walls with an algae scrapper.
2. Trim the plants occasionally and take out the clippings.
3. Clean decor and plants with a soft toothbrush.
4. Skim surface of the substrate if sand is used and gravel vac if gravel is used. Avoid uprooting plants

Pro Tip: During the breeding season, make sure you don't damage your Honey Gourami's bubble nest while cleaning the plants.

Substrate

Creating a substrate that mimics their natural environment is as essential as other things. While they adhere to the middle and surface levels, you still need a good substrate for this labyrinth fish.

Layer the base of the tank using fine grains of the substrate. You can use both sand and gravel to create the base. In the wild, you can find plenty of rocks, plants, and driftwoods. Keep that in mind while creating their substrate.

Keep the substrate at least 2 inches deep. And make sure underwater plants or decorative items are firmly fixed on it.

Pro tip: A dirty substrate can make the aquarium cloudy. So, clean it beforehand to avoid any issues.

Is the Honey Gourami Right for You?

Before you commit to this species, here’s an honest assessment of whether it fits your setup and experience level.

• One of the best gouramis for beginners. Hardy, peaceful, and forgiving of minor water quality issues. Everything a first gourami should be.
• Perfect for 20-gallon planted community tanks. They shine in smaller setups where larger gouramis would feel cramped.
• Great alternative to dwarf gouramis. You get similar personality and beauty without the iridovirus risk that plagues dwarf gouramis.
• Not ideal if you want a bold, flashy centerpiece. Their beauty is subtle and they is overshadowed by more colorful tank mates.
• Requires floating plants for confidence. Without surface cover, they will hide and never show their best colors or behavior.
• Is kept in small groups. Unlike dwarf gouramis, you can keep a male with 2-3 females for more natural and interesting behavior.

Community Tank Mates

Honey Gouramis are shy and need considerable time to blend in with their tank mates. They are peaceful fish and can easily get along with a good range of fish species.

But since they are reserved, pay great attention to the species you will house them with. Their ideal tank mates should not be fin nippers. Also, they are quite small, so choose a fish that can can’t fit them in their mouths.

They are social and humble but can act aggressively, especially males. If the amount of food that you are putting in isn’t enough, you will see the males hostile towards their mates. So it is good to focus on these areas.

Here’s a list of some great tank mates for your Honey Gourami.

1. Rosy Barb
2. Dwarf Barb
3. Cherry Barb
4. Sparkling Gourami
5. Cory Catfish
6. Zebra Danio
7. Celestial Pearl Danio
8. Kuhli Loach
9. Oto Catfish
10. Ember Tetra
11. Rabbit Snail
12. Mystery Snail

Poor Tank Mates

As much as they are good at grouping up with different fish, they are small and thus an easy target for these fish species.

1. Cichlids
2. Red tail Sharks
3. Rainbow Sharks
4. Paradise Fish
5. Betta Fish
6. Tiger Barbs

Breeding

Breeding Honey Gouramis is pretty simple and intriguing. In this guide up till now, I have walked you through their origin to their aquarium setup. And now comes the most important part.

Unlike the complex details of Betta fish breeding, the breeding requirements of the Honey Gourami are fairly simple for a beginner. Honey Gouramis are sexually dimorphic, which means there are visible differences between a male and a female. Here is a video above by Todor Vankov that shows the cycle.

But before we get started, make sure males and females are equal in amount. If there are too many males, they will start fighting one another to win over the limited females.

Purchase a separate breeding tank for them. A 10-gallon water tank is ideal. While setting up their breeding tank, keep the water 6 to 7 inches high.

Then, heat up the water up to 84° F. You can either use a heater for that or go for a towel to cover the surface. Keep the acidic level at 7.0 with the water hardness around 8 KH.

Apart from gauging the water conditions, feed them a good-round diet.

Also, introduce thick vegetation to the breeding tank throughout. Males will use them to build a bubble nest.

Before spawning, the males become more vibrant and develop a deep black or light brown stripe. The stripe is apparent from their heads to the end. You can also see its throat turning deep blue, which is a clear spawning indication.

Before approaching a female, the male will build a bubble nest. Once the fish is done, it will start swimming around the female until she is convinced to follow him to the bubble nest.

At the time of spawning, the male will hold the female to prompt spawning. Once the female swells with eggs, it will start laying eggs in water. The male will instantly catch the eggs with his mouth to lay in the bubble nest.

After they are done spawning, separate the female. Even though Honey Gouramis are not aggressive fish, males will show hostility towards the mothers. They are possessive and don’t appreciate anyone around the eggs.

Female Honey Gourami can lay up to 300 eggs in different spawning rounds. The male monitors them and fertilizes the honey gourami eggs, which takes 2 to 4 days.

The fry will start swimming after 2-3 days and it is good to remove the male at this point. Because the babies are puny, they need to be looked after properly. Once the larvae is hatched, they will use their yolk sacs for a couple of days.

Start feeding them infusoria and liquid fry food after a week or two. Once they are bigger and stronger, give them access to baby brine shrimps.

If you want to ensure a solid growth of the labyrinth organ, I recommend covering the aquarium surface with plastic wrap. This will increase humidity, leading to proper labyrinth organ growth in babies.

Food and Diet

In the wild, they are fed on a variety of diets. Even though they are omnivorous fish, you can call them carnivorous fish, too. Because they can consume both plants and protein-filled foods.

Honey Gouramis love to see variations in their diet. So, making them happy while keeping honey gouramis healthy at the same time holds great value.

To boost their longevity, give them a mixed diet of vegetables and meat. Some great recommendations for vegetables are vegetable tablets, plant material, lettuce, and cucumber. While trimming the plants, you can offer them that, too. This will help you prevent them from attacking the plants.

But meaty foods remain the core diet, so don’t skip that. You can give them bloodworms, white worms, mosquito larvae, flakes, pellets, and brine shrimp. Fluval bug bites are a great staple and will enhance their color.

While baby brine shrimp is the primary source of protein for baby honey gouramis, you can you large brine shrimps for adults.

As compared to other fish, they are shy. Other fish who are fed on the same diet can easily eat off their share, leaving them starving. While feeding the fish separately is almost impossible, you can make changes to their timings.

Lastly, feed them twice or thrice a day, and notice that they finish the food odd within 3 minutes.

Common Health Problems

They can withstand environmental changes, but their labyrinth organ is sensitive to drastic temperature shifts.

An unclean water tank can lead to a bacterial infection called fin rot. There are other diseases too that they are prone to. To keep these ailments at bay, keep the tank clean and manage the diet as recommended.

Fin Rot

They are susceptible to fin rot, a common disease caused by unclean water.

The symptoms are:

1. Black, while or brown spots on fins or other body parts.
2. Inflammed skin
3. Lethargy
4. Loss of appetite

Ich

This is a common fish disease. Honey Gouramis are resilient, but other fish suffering from ich can easily affect them.

The symptoms are:

1. White spots on the body
2. Scraping the body against the aquarium surface

Velvet Disease

Velvet disease primarily occurs due to the presence of parasitic dinoflagellates.

The symptoms are:

1. Scratching against rough objects or surfaces
2. Loss of appetite
3. Loss of color
4. Clamped fins

These ailments is avoided if you maintain water quality and keep overall health preservation. Velvet spreads rapidly and, in case your honey gourami is affected, isolate it from other fish.

What It Is Actually Like Living With Honey Gourami

Gouramis move slowly and deliberately through the tank, using their modified pelvic fins to “feel” their surroundings. Watching them gently tap plants, substrate, and decorations with those threadlike feelers is genuinely mesmerizing.

Males display regularly, spreading their fins and deepening their colors. In good conditions, this happens daily and is one of the most visually striking behaviors in freshwater fishkeeping.

Gouramis surface breathe. You will see them rise to the top and gulp air several times an hour. This is normal labyrinth organ function, not a sign of low oxygen.

In a well-planted tank, gouramis are surprisingly curious. They investigate new decorations, follow your finger along the glass, and react to activity outside the tank.

FAQs

How the Honey Gourami Compares to Similar Species

Want a peaceful labyrinth fish for a community tank? Get a honey gourami. Want more color and size? Get a pearl gourami. Avoid dwarf gouramis from chain stores unless you are willing to gamble on Iridovirus.

The obvious comparison is the dwarf gourami, and I’ll be blunt: for most keepers, the honey gourami is the better fish. Dwarf gouramis are flashier, no question. A fully colored male dwarf gourami is one of the most striking small fish in the hobby. But the prevalence of Dwarf Gourami Iridovirus (DGIV) in commercial stock makes them a gamble. Honey gouramis don’t carry this disease, they’re hardier overall, and they live just as long when properly cared for. The only real advantage of the dwarf gourami is raw color intensity.

The sparkling gourami is worth considering if you have a nano tank setup. Sparklers are tiny (under 1.5 inches) and make audible croaking sounds, which is genuinely delightful. They’re more sensitive than honey gouramis and need very calm tank mates, but in a dedicated nano setup they’re fantastic. Honey gouramis are the more versatile choice for general community tanks, while sparkling gouramis are specialists for smaller, quieter setups.

Closing Thoughts

If you’re looking for a peaceful, colorful fish to add to your community tank or planted aquarium, the honey gourami is perfect for you. These little guys are social and get along well with other fish, making them an ideal choice for those who want a lively tank without any drama. Have you kept honey gouramis before?

The neon tetra is the canary in the coal mine for every aquarium. If your neons are dying, your tank has a problem. No exceptions. Keep fewer than 10 and they stress. Keep them in uncycled water and they drop like flies.

Neon tetras are the canary in the coal mine. If they are dying, your tank has a problem.

What Care Guides Get Wrong

The most common mistake I see with neon tetras is keeping too few. Guides will say “minimum 6” and leave it at that. In reality, these fish behave completely differently in a proper group of 8 to 10 or more. Keeping just 3 or 4 often leads to stress, hiding, and fin nipping that wouldn’t happen in a larger school. Another thing most guides miss is how much lighting and decor affect this species. Neon tetras look washed out under bright white LEDs on a light substrate. Dim the lights, add some tannins, use a dark background, and you’ll see colors you didn’t know they had. I’ve also noticed that many care sheets recommend overly broad water parameters. Yes, neon tetras are adaptable. But “adaptable” doesn’t mean they’ll thrive in just anything.

The Reality of Keeping Neon Tetra

Mass-bred neons are weaker than they used to be. Decades of commercial breeding in Southeast Asian fish farms have produced neon tetras that are genetically less robust than their predecessors. This is not controversial. It is widely acknowledged across the industry. You need to buy from reputable sources and quarantine properly.

Neon tetra disease is real and there is no cure. Pleistophora hyphessobryconis causes progressive muscle degeneration, color loss, and death. There is no treatment. Infected fish must be removed immediately. This disease is most commonly introduced through sick new additions, which is why quarantine is not optional with neons.

They need more stable conditions than most guides suggest. Neons handle a reasonable parameter range, but they do not handle fluctuations well. A tank that swings between 74 and 80 degrees throughout the day, or pH that drifts with water changes, will slowly kill them. Consistency matters more than hitting exact numbers.

Biggest Mistake New Owners Make

Adding them to a tank that has not finished cycling. Neon tetras are not cycling fish. The ammonia from an incomplete cycle stresses them, weakens their immune system, and opens the door for disease. Wait until your tank is fully established.

Expert Take

In my 25+ years in the hobby, I have watched neon tetras go from one of the hardiest community fish to one of the most fragile. Mass breeding has weakened the genetics, and most losses come from poor acclimation and unstable water, not from the fish being difficult. Buy from a reputable source, quarantine properly, and keep the water stable. Do those three things and neons will live for years.

Key Takeaways

• School size is not optional. Keep 10 or more. Fewer than that leads to stress, hiding, color loss, and fin nipping that disappears in a proper group.
• Neon tetra disease has no cure. Quarantine every new batch. One sick fish introduced without quarantine can wipe out your entire school.
• Stability matters more than exact numbers. A pH that stays at 7.2 is better than one that swings between 6.5 and 7.5. Consistency keeps neons alive.
• They are not cycling fish. Add neon tetras only to fully cycled, established tanks. They are often the first to die in new setups.
• Color takes time and conditions. Dark substrate, dim lighting, and tannin-stained water bring out colors you will never see under bright white LEDs on white gravel.

Species Overview

Classification

What Is A Neon Tetra?

Neon Tetra is a small to medium-sized tropical fish that belongs to the Characin Family. They are beautiful freshwater, hardy fish, known for their peaceful nature. Neon Tetras are schooling fish that do well in a group of 10 or more. There are many types of Neon tetras and each of them is equally amazing. They usually come from soft, acidic water from the Amazonia.

Different Types

Here are some of the most common types of Neon Tetra.

True Breeds

True Neon tetra or wild neon tetras are blue and red with silver white color. They possess bright blue color on both of their sides, i.e, from their eyes to the adipose fins. Their body is of red color from the anal fins and exceeding to the tail with transparent fins and tails.

The wild neon tetras or True neon tetra have a silver and white body that grows no longer than 1.2 inches. These are peaceful fish, smaller in size, and enjoys the company of at least 6 other fish. They usually occupy the middle tank levels.

Long Fins

The long fin neon tetra is a captive variety of neon tetras that are similar in appearance to true neon tetra. However, they have long fins twice the length of true neon tetra. Besides the size of their flowy, long fins, the long fins of neon tetra are identical to true neon tetra in terms of their appearance, lifespan, or living water conditions.

Gold Head

Gold neon tetra or glowlight neon tetra has a red and silver body with beautiful blue eyes and a gold-red stripe running from its snout to the tail. Despite their beautiful patterns, they are leucistic, i.e, their bodies are transparent with a peachy silver hue.

Diamond Neon Tetras

These tetra species possess a diamond-shaped patch on the back of their bodies, between their eyes and a dorsal fin. Hence, the name. Diamond Neon tetra is a product of selective breeding and many buyers prefer to buy them with they are adults since juvenile diamond tetras are bland in color. However, as they grow, they develop beautiful colors that are appealing to the eyes with horizontal blue stripes and red stripes down their bodies.

Black

They are commonly called black neons only. These species of neon tetra have a unique and striking appearance with an orange-colored semi-circle above their big eyes. Two horizontal lines run from their gill cover to the caudal fin. One line is black while the other one is bluish white. The entire body of black neon tetra is greyish brown with shimmery marks of yellow and green.

Red

Red neon tetra or Cardinal tetra has an uncanny resemblance to the true neon tetras, but they are slightly longer than the true neons. Cardinal tetras have blue stripes that run from their eyes to the tails. There is a red stripe below the blue stripe which extends from the head to the tail.

Green Tetra

False neon tetra or Green Neon tetras are often confused with their close cousins; Cardinal tetras or true neon tetra because of their overall appearance. They have a light red color on the lower part of the body like neon tetras while the upper part has a bluish-green color that looks gorgeous. The head and back of the green tetras are also green colored, hence, the name.

Origin and Habitat

Neon tetras come from the tropical areas of Amazonia which makes them tropical fish. Neons prefer warm water and they originate from Western Brazil, South America, Southeastern Columbia, and Peru.

However, the wild bred variety of neon tetras lives in headwaters of the River Amazon, Tiger, Napo, and Yarapa. In their natural habitat, they is found in clear water streams or blackwater. But mostly, neon tetra is now commercially bred.

Appearance

Neon tetras are graced with a light blue black and silvery white abdomen. The bodies of Neon tetras are spindle shaped with a blunt nose. From the base of the adipose fin to the close runs an iridescent blue stripe and from the middle body to the base of the caudal fin runs an iridescent red stripe.

The anal fins of Neon tetra are almost transparent and most neon tetras develop an olive green shimmery lining on their backs. The most prominent feature of neon tetras is when at rest, the fish becomes silver and when it is active during the day, it again becomes red and blue.

One thing that surprises new neon tetra owners: these fish lose almost all their color at night. If you check on them with a flashlight after the lights go out, they will look pale and washed out. That is completely normal. If they still look pale during the day with the lights on, that is a sign of stress, disease, or poor water quality. Learn the difference early and you will save yourself a lot of unnecessary worry.

Average Size

The neon tetra is a small, peaceful fish that grows no longer than 1.2 inches in length or 3 centimeters.

Lifespan

Neon tetra species are an investment because they have a great life expectancy when provided with optimal water parameters and tank conditions. A healthy neon tetra lives for up to 8 years or longer in captivity.

Tank Care Guide

Neon tetras are hardy fish that can withstand varying water parameters and tank conditions. However, when it comes to the cleanliness and hygiene of your tank, neon tetras are no exception. Neon tetras need crystal clear, bacteria-free water to do well in your home aquariums.

Therefore, to keep your neon tetra happy and healthy, follow this guide.

Aquarium Setup

Since neon tetra is a schooling fish, they should be kept in a group of 10 fish. However, a group or shoal of at least 10 neon tetras is highly recommended to avoid stress and aggression in your fish. Also, neon tetras live in the mid-upper levels of the tank. Therefore, choose plants and other fish species accordingly.

Tank Size

If you’re keeping neon tetras in small numbers, for example; one or two fish in a single tank, then size doesn’t matter. They are such small fish that can easily fit into a 2 or even 1-gallon tank.

However, as mentioned above, neon tetra is a shoaling fish that enjoys the company of other fish. Therefore, for keeping a group of 10 or more, I recommend a bare minimum of 10-gallon tank size. Also, as they are mid to upper-level swimmers, a taller tank works the best than a wider one.

Water Parameters

In their natural habitat, neon tetra enjoys slightly acidic water with a water temperature of around 70-79°F. The pH of South American regions is more or less 6.8. Thus, they should be provided with similar water parameters to ensure their health.

Water Temperature: The ideal water temperature range is around 73°F to 78°F.

pH range: The recommended pH range for an aquarium tank is between 6 to 7.

Water Hardness: The neon tetra prefers soft and slightly acidic water with a water hardness of no more than 10 dGH.

Filtration and Aeration

Neon tetra, in the wild, is a very hardy fish. However, in captivity, you need to take care of their ecosystem since they develop fatal diseases detrimental to their well-being. Therefore, proper filtration and aeration in a fish tank are essential.

Many aquarists use air pumps to promote aeration. They are okay to use, however, not necessary. If the air pump becomes a necessity, the reason is you have overstocked your fish tank. Air pumps create bubbles in the water and break the surface tension. But there are more easy ways to promote aeration in your tank. These are:

1. Aquarium Filter: Aquarium filters are excellent to promote aeration and oxygenation in the tank. For maximum aeration, I highly recommend getting a filter that is powerful enough for your neon tetra tank.
2. Powerheads: Powerheads supplement your aquarium filter and are placed on the side of your tank, connected to an air hose. They add water movement and promote aeration in your fish tank.
3. Spray Bar Aerators: Spray bar aerators are attached to your filter outlet that sprays the water. They are fitted in the tank horizontally. I highly recommend space bars if you have dead spots in your aquarium.

Best Aquarium Filter for Them

Neon tetras are small fish that need a lot of oxygen in their tank. Without proper aeration and oxygenation, neon tetras will suffocate to death.

The recommended filters for a small fish like neon tetra are a sponge filter or a hang-on back filter. However, if you have a larger community tank with lots of fish and plants, I recommend canister filters.

The best filters for neon tetras are those that perform biological, chemical, and mechanical filtration and provide movement in the water. I also recommend a drip filter that creates a waterfall effect and promotes oxygenation.

Pro Tip: While installing a filter, make sure you cover the intake as neon tetra is a small fish that can easily be sucked into the filter.

Lighting

In their natural habitat, neon tetra lives in brackish or blackwater. And so, thousands of leaves cover the river streams making their ecosystem dimly lit. We also suggest mimicking their natural environment to keep them happy. Thus, a dimly lit aquarium is the best bet for your fish.

If you have aquatic plants, make sure to get those that thrive in low light. Otherwise, you can get floating plants that cast dark shadows on your fish.

Aquatic Plants and Decorations

Neon tetra appreciates a densely vegetated aquarium. Also, aquatic plants help in the breeding tank while mating and spawning. In a community tank, neon tetras like to swim freely in groups where they feel safe. However, when they feel threatened, they like to hide in plants and other decorations. Therefore, aquatic plants are necessary for the neon tetra tank.

I recommend keeping tall plants, i.e, Ludwigia repens, Brazilian pennywort, vallisneria, cabomba, or Cryptocoryne wendtii. Floating plants also add great colors to the aquarium and provide them shade from direct sunlight. I recommend frogbit, dwarf water lettuce, or red river floaters.

Live plants also help filter out the water by removing nitrates from water. Additionally, for plant decors, you can get driftwood, logs, and castle with hiding places and bubbles to adorn your aquarium.

Substrate

Neon tetra fish is not finicky about substrates because they are mid to top level swimmers that rarely settle in the bottom.

However, avoid using Aragonite sand as a tank substrate. That’s because it is made of Calcium Carbonate which will increase the calcium and carbonate levels in your tank and mess up your fish ecosystem. If you opt for a densely planted tank, use a planted tank substrate.

Community Tank Mates neon tetras

The neon tetra is a small and non-aggressive fish that get along with other fish similar in size and temperament. Also, neon tetras are top to mid-level swimming fish, make sure to add the tank mates that are mid to top-level dwellers.

The best community tank mates for neon tetras are:

1. Harlequin rasboras
2. Zebra Danios
3. Hatchetfish
4. Guppies
5. Chili Rasboras
6. Dwarf Gourami
7. Zebra Loach
8. Corydoras Catfish
9. Kuhli Loach
10. Otocinclus Catfish
11. Clown Pleco
12. Bristlenose Pleco
13. Freshwater shrimp

I don’t recommend keeping neon tetras with large, aggressive fish of around 3 to 4 inches in size that may bully, harm, or eat your neon tetras.

Breeding

Many aquarists struggle breeding neon tetras in their home aquariums because to breed neon tetras, you need special water conditions that should be followed religiously. In a breeding tank, the water temperature should not exceed 75 degrees. Also, the breeding fish in the tank should be separated from other fish. The eggs and fry of neon tetra are photosensitive, therefore, little to no light should be available.

In essence, you cannot breed neon tetras in the same standard tank. Thus, invest in a separate tank to breed neon tetras. The video above by KeepingFishSimple offers a unique method of breeding these fish.

Setting up a separate breeding tank

First of all, before breeding neon tetras, feed them with high-protein live food at least three days prior to breeding. You can feed them brine shrimp, tubifex worms, and bloodworms to achieve initiate the spawning cycle. 

1. Prepare at least a 5 to 10 gallon tank with a lid and leave them in the tank for a full day
2. Maintain the proper water parameters. The water should be soft and slightly acidic with a pH of 6.0 to 6.2
3. Install the heater to maintain the water temperature at 75 degrees. Invest in an aquarium thermometer to closely monitor the temperature.
4. Keep the breeding tank densely vegetated with floating plants like Hornwort as neon tetras are egg scatterers and scatter their eggs onto the plants. Also, keep your tank in a dark or dimly lit room
5. The eggs of neon tetras release early in the morning and the fish will spray the eggs onto the plants. Once you identify neon tetra eggs, remove the breeding fish from your tank as neon tetras eat their own unhatched eggs
6. The eggs of neon tetra hatch in around 22 to 30 hours and in 3 to 4 days, the fry will be swimming freely. The neon fry should be fed infusoria or some other liquid-prepared fry food as soon as they start swimming
7. Once the fry gets bigger, you can switch their diet to freshly hatched brine shrimp, powdered eggs, or fry food
8. Once the neon tetra fry is almost a month old, you can feed them regular adult neon tetras food

Food and Diet

Neon tetras eat everything since they are omnivorous. In the wild, they eat everything that fits their mouth. Algae, larvae, shrimps, and other food.

However, captive-bred neon has a varied diet that is high in protein to ensure healthy colors and a longer lifespan. I recommend feeding neon tetras with a balanced, high-quality flake or frozen foods, and sinking micro pellets as these fish are small. You can also treat your neons with freeze-dried or frozen foods such as bloodworms or frozen brine shrimp.

• Brine Shrimp
• Earthworms
• Maggots
• Daphnia
• Frozen Blood Worms
• Fish Flakes
• Tubifex Worms
• Mysis Shrimp
• Cucumbers
• Grapes
• Strawberries
• Chicken
• Fish
• Egg Yolk
• Beef

Common Health Problems and Disease

Though many aquarists believe neon tetras are hardy. However, for novices, it is a challenging pet. That’s because neon tetras are blackwater fish that are easily killed by bacterial infections. Also, overbreeding has led to weaker less hardy strains of neons.

These diseased fish often shows no symptoms of illness. Therefore, neon tetras need crystal clear and clean water that is only possible with mature aquarists in mature aquarium settings with a proper filtration system and substrate that is uncleaned for at least two months.

How To Cope-Up With Disease

Seasoned aquarists seldom experience any neon tetra disease problems because they know how to raise them well. Neon fish thrive in bacteria-free, crystal-clear water with exceptional aeration. However, if you keep neon fish in a tank teeming with bacteria, they will die rapidly because their immune system is vulnerable to bacteria.

Here’s how you can fight neon tetra disease.

1. Over-filter your tank with a canister, sponge filter, or a hang-on back filter.
2. Keep your neons in the tanks that are established for over five months.
3. Keep the water crystal clear and clean. Do regular water cycling and keep track of aeration.
4. Install an in-line UV unit.

Here are some of the common neon tetra diseases.

Disease

Named after neon tetras, this disease is not only limited to neon tetra fish. However, it was first diagnosed in a neon tetra fish. Unfortunately, it is devastating to have a fish with neon tetra disease in a community tank because it is fatal and affects almost all fish of varying sizes. This disease is spread by a diseased fish in an aquarium. Thus, quarantining your new fish before introducing it to a community tank is the best thing to do.

If you come across any fish with neon tetra disease, remove it from the fish aquarium before it dies. The spores in your aquarium tank cause neon tetra disease. Thus, careful cleaning and regular maintenance are imperative to avoid these diseases,

Symptoms of Neon tetra disease:

1. Restlessness at night
2. Erratic fish swimming behavior
3. Fish becomes inactive and lethargic
4. Loss of colors on fish’s body
5. Formation of cysts in muscles
6. Curved spine

Cotton Wool Disease

The cotton wool disease is caused by fungal infections in the fish. It happens when two fungi, Saprolegnia and Achyla, affect your neon tetra’s immune system. The first sign of the cotton wool disease is the white fluffy appearance like a bulge on their mouth. As the infection worsens, it becomes grey or red in color. 

Symptoms of Cotton Wool Disease:

1. Loss of color around the mouth
2. The cotton-like abnormal bulge on their mouth
3. Lethargy and less movement
4. Loss of appetite and solitary behavior

Fish Tumor

Many aquarists confirmed that neon tetras can get tumors that appear as lumps or bumps on the fish’s body. Therefore, if you notice abnormal growth on your fish’s skin, experts recommend removing it from the tank before it spreads to other fish in the tank.

Symptoms of Fish Tumor

1. Pea-sized growth on the mouth
2. Difficulty in breathing and eating

How to Prevent Diseases in This Type of Fish?

Prevention is always better than cure and to keep your neons away from diseases, maintain optimal water conditions and check your fish’s health while buying from the fish store. I highly recommend buying fish from fish farms or a reputable supplier. Once you get your fish, keep it quarantined for at least two weeks before transferring it to the community tank. Also, always get your fish food supplies from a reputable source.

The foremost thing to do is to maintain a healthy environment in your tank. I recommend you clean your aquarium every week. Also, change your water anywhere from 15 to 50 percent depending on your water parameters. This will keep your nitrate levels low and keep your fish healthy.

Differences Between Male and Female

The differences between male and female neons are close to none. However, female fish is bigger and bulkier than males with more round bodies. Also, the male fish has a straight blue line on their bodies while the blue stripe on the female fish is more bent.

FAQs

Is the Neon Tetra Right for You?

Before you add a neon tetra 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. Neon tetras 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 neon tetra 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.

What It Is Actually Like Living With Neon Tetra

A large school of healthy neons in a planted tank is still one of the most beautiful freshwater displays you can create. The blue stripe glows under moderate lighting in a way that never gets old.

They are most active during morning and evening hours. Mid-day they will settle into a loose school in the middle of the tank.

Neons are peaceful to a fault. They will not compete with aggressive feeders and can go hungry in a tank with pushy tank mates. Watch feeding time carefully.

In a school of 15 or more, you start to see real schooling behavior rather than just a group of fish swimming near each other. The difference between 6 and 15 is dramatic.

Species Comparison

Choosing between similar species is tricky. Here’s how the neon tetra stacks up against some common alternatives.

Neon Tetra vs. Cardinal Tetra: Both are iconic small tetras with a glowing blue and red stripe, but the cardinal tetra has red coloring that extends the full length of the body, while the neon tetra’s red is limited to the belly. Cardinals are considered slightly more delicate and prefer warmer, softer water. They also will cost more. For most community tanks, either species works beautifully, but if your water is harder or you’re on a budget, the neon tetra is the easier pick. Check out our Cardinal Tetra care guide for a detailed breakdown.

Neon Tetra vs. Green Neon Tetra: The green neon tetra is smaller and more delicate than the neon tetra, staying under an inch in practice. It has a more subtle blue-green stripe and lacks the bold red of the standard neon. Green neons are better suited to nano tanks and blackwater setups, while standard neons are more versatile and widely available. Check out our Green Neon Tetra care guide for a detailed breakdown.

Final Thoughts

There are many types of neons. All with a peaceful nature and vibrant, enchanting colors that are pleasing to the human eyes. The Neon tetra fish is small and colorful that makes a beautiful addition to your home aquariums. However, they come from blackwater that is low of bacteria, so, you should aim to mimic their natural environment to provide them with the best living conditions that they will cherish for the rest of their adorable lives.

The black neon tetra is the overlooked workhorse of planted tanks. It does not have the flash of a neon or the drama of a cardinal, but it schools tighter, lives longer, and handles a wider range of water conditions than either one. This is the tetra that experienced keepers come back to.

The black neon tetra is what experienced keepers switch to after they get tired of replacing neons.

What Most Care Guides Get Wrong About Black Neon Tetra

The most common mistake I see with black neon tetras is keeping too few. Guides will say “minimum 6” and leave it at that. In reality, these fish behave completely differently in a proper group of 8 to 10 or more. Keeping just 3 or 4 often leads to stress, hiding, and fin nipping that wouldn’t happen in a larger school. Another thing most guides miss is how much lighting and decor affect this species. Black Neon Tetras look washed out under bright white LEDs on a light substrate. Dim the lights, add some tannins, use a dark background, and you’ll see colors you didn’t know they had. I’ve also noticed that many care sheets recommend overly broad water parameters. Yes, black neon tetras are adaptable. But “adaptable” doesn’t mean they’ll thrive in just anything. In my experience, keeping them closer to their natural soft, slightly acidic conditions brings out the best color and longevity.

The Reality of Keeping Black Neon Tetra

The name is misleading. This is not a black version of a neon tetra. It is a completely different species (Hyphessobrycon herbertaxelrodi) with a different look, different behavior, and different care profile. The name causes confusion constantly, but the two fish have nothing in common except the word “neon.”

Setup determines everything about their appearance. On white gravel under bright lights, black neon tetras look gray and unremarkable. On dark substrate with moderate lighting and plants, the iridescent stripe glows and the contrast between the light and dark bands becomes dramatic. This fish rewards a properly designed tank more than almost any other tetra.

They are nearly indestructible. Black neon tetras tolerate a wide range of water parameters, handle temperature swings better than most tetras, and rarely get sick. They are one of the hardiest small tetras available and an excellent choice for newer keepers who want something more refined than a standard neon.

Biggest Mistake New Owners Make

Keeping them in a bare, brightly lit tank and then wondering why they look boring. The entire appeal of this fish depends on the setup. Get the background, substrate, and lighting right and they transform.

An Overview of Black Neon Tetras

Classification

What are Black Neon Tetras?

Black Neon Tetras, scientifically recognized as Hyphessobrycon herbertaxelrodi, are part of the Characidae family from the order Characiformes.

In the aquarium trade, their generic names are Black Neon Tetra, Neon Black, or Black Tetra. Regardless of which name of Black Neon tetras you use, they know how to make their way around.

In the wild, the Black Neon tetras sustain themselves on brine shrimp, algae, and bloodworms and prefer traveling through middle and upper levels of water.

Origin and Habitat

Originating from the basins, small rivers, and flooded forests of Brazil and Bolivia, Black Neon Tetras are now housed in aquariums across the world. They were first sighted in 1936 by the American Ichthyologist George Sprague Myers. Ever since their classification, they have never failed to amaze aquarists.

The streams of their natural habitat are stained brown because of tannins or decaying plant matter. In their natural habitat, Black Neon Tetras prefer warmer levels of water, ranging from 70° to 82° F. And stick to small rivers and inlets where, in some localities, you can find dense plants.

The water current of their natural habitat is low-to-moderate and slightly acidic, with a pH level ranging from 5.5 to 7.5.

Appearance

These small, little Black Neon Tetras give a much more beautiful touch to your tank water with their overall body coloring than other tropical fish.

They got their name after their base body color and neon stripes. From the pair of these two bars, the first one is a white stripe that looks shimmery, followed by a thick black stripe.

The foot color of their bodies is velvety black and on top of the base color are two strikingly beautiful-colored bands. These stripes run horizontally from their gill cover to the end of their tail fin. Apart from being beginner-friendly, they seize the attention of aquarists with their physical appearance.

Compared to the small size of the Black Neon Tetra, its transparent fins, including caudal, dorsal, and pelvic pin appear somewhat larger.

The Black neon tetra has a rounded mouth and rounded head and looks sleek in appearance. Female Tetras, however, look fuller from their bottoms and their underbellies look more prominent while being pregnant.

Differentiating a male Black Neon Tetra from a female Black Neon Tetra is almost impossible. They are so small and you can’t see any other apparent sign of gender difference other than knowing the female is larger.

Lifespan

The average lifespan of a Black Neon Tetra is around 5 years in captivity. In their natural habitat, adhering to health and fitness is hard. Therefore, some of them only make it up to a few months.

You can replicate those conditions in the tank. For a healthy lifestyle, give them a good-round diet and a peaceful environment.

The Black Neon Tetra is a hardy fish and can survive uneven water parameters and non-ideal water quality. But, failing at meeting their basic needs can put them through stress and cause fatal diseases.

Average Size

The size they get is around an inch. Some of these fish can grow a maximum size of 1.5 inches in aquariums. In the wild, they can stretch themselves up to 2 and a half inches, but this size is not attained for captive-bred fish to reach.

Care

There are no special care requirements for a Black Neon Tetra. They are very easy-going, suitable for community aquariums, and eat pretty much everything you put in their tank. From flakes, bloodworms, and brine shrimp to frozen-dried food, these beautiful fish prefer a variety of easy-to-get foods to consume.

As long as you understand their natural behavior, needs, and things essential for them to thrive, you will have a good time handling them.

Black Neon Tetras prefer streaming in moderate water currents. The water does not have to be crystal-clear because they live in brown-stained water that is above 70° F and below 82° F in the wild.

Have at least a 20-gallon tank for Dark Neon Tetras. They might look too small for the tank, but they are schooling fish and live in groups of 6 to 10. Larger tanks will allow them to demonstrate their best natural behavior.

Also, a large tank, ideally a Biotope aquarium, can give them enough swimming space to enjoy their me-time and still conduct group gatherings.

Black Neon Tetras sustain themselves on crustaceans, algae, and insect larvae in their natural environment.

They are schooling fish and very amiable, and living alone can easily stress them out. So, keep at least half a dozen of them together, which is actually the bare minimum.

Black Neon Tetras stay active throughout the day and take rest during the night. And it’s very unlikely for them to show signs of aggression or hostility. They prioritize healthy company over solitude and love extending their company with their community tank mates.

Like other fish, Black Neon Tetras are also susceptible to some common diseases. But don’t worry!

Here are some really important things to consider before adding a Black Neon Tetra to your aquarium and how you can avoid unpleasant events in the best way possible.

Aquarium Setup

The key to pleasing your Black neon tetra is to replicate their natural environment as closely as possible.

In the wild, Black Neon Tetras live in small creeks and shallow streams full of plants. These plants provide them shade under where they can rest all through the night. And during the day, they hurtle through acidic water and look around for food.

Black Neon Tetras hardly travel down to the bottom and spend most of their time remaining in the upper levels.

The type of water Black Neon Tetras live in contains decomposed plant matter, which gives way to tannin. The tannin then makes the water brown and highly acidic.

Even if their natural water conditions are not well regulated, try replacing them with something more convenient while constructing their habitat.

Tank Size

To ensure that your Black Neon Tetra is living a quality life, tank size is as important as any other factor involved in their fitness.

Black Neon Tetras live in groups. So technically, they need larger tanks to swing around at their own pace.

The minimum tank size is 20 gallons for a Black Neon Tetra, but the number can go up to 40 gallons if there are other community tank mates with them.

Pro tip: Black Neon Tetras are pros at jumping out of the tank. To ensure their safety and stop them from displaying their jumping skills, secure the tank with a lid.

Water Parameters

Contrary to what most people believe, the water in their native homes is not clean or transparent. Instead, it is tea-colored, high in pH levels, and filled with decaying plant matter.

While creating their aquarium, gauging the right parameters is important to keep your Black Neon Tetra healthy. They prefer swimming in moderate water currents. So, make sure the current is not too low or too high.

The water temperature should be between 70°F to 82°F degrees, with the water hardness around 6Kh. Black Neon Tetras in their habitat survive disturbed acidity levels. To keep these problems away from intruding on your fish, keep the water parameters similar to what they are naturally intimate with.

Pro Tip: A Black Neon Tetra that is newly introduced to the aquarium can have a hard time adapting to the environment. It's better to keep checking on them every now and again and see how they progress through the first days.

Filtration and Aeration

Filtering out the water frequently is another important factor that leads up to their overall physical fitness.

Even though Black Neon Tetras are tiny and don’t produce too much waste, the cumulative waste of 6 to 7 tetras is enough to pollute the water. If you don’t weed out the waste material on time, your Black Neon Tetras will end up with high ammonia and nitrate levels.

Once a week, strain out at least 25% of water and add fresh water to their tanks. Also, purchase a strong filtration system like a hang-on-back filter or a canister filter.

Pro Tip: Keep at least 60% 75% water in your tank while cleaning out the dirt or waste. Drastic changes in water is fatal for your fish.

Lighting

Black Neon Tetras don’t expose themselves to luminous lighting. In fact, Neon Tetra eggs are extremely sensitive to brightness. Also, in the dull light, their bands look more prominent.

So, try to keep the aquarium’s light of your Black Neon Tetras subdued. You can use low LED light to make the tank dimly lit. But make sure the aquarium is not completely deprived of natural lighting because it keeps the plants healthy.

Aquatic Plants and Decorations

As with most Tetras, filling your tank with dense live plants is crucial to making Black Neon Tetras feel at home. The regions they call home contain rotting plants, driftwoods, and twisted roots.

Despite their preference for staying close to the surface of their tank, they still explore their surroundings.

They conduct their family gatherings, do food hunting and keep themselves floating around during the morning hours. To recharge their energy, they travel to the bottom levels at night. Adding caves to the tank will allow them to do that.

Some great recommendations for live plants are Java Moss, Brazilian pennywort (one of the best floating plants), Amazon sword, Cabomba, Vallisneria, Cryptocoryne wendti, Anubias nana, and Ludwigia repens.

Not only these plants will add up to your aquarium beauty, but they will also keep the water oxygenated and free from ammonia.

Pro Tip: Place plants in the tank at a fine distance from one another so the fish can easily roam around and explore.

Tank Maintenance

You don’t need to fuss over cleaning their tanks. It’s easier than you think. Here are some really easy tips to get you started.

How to clean their tank

1. Start cleaning off debris from the substrate using a gravel vac if the substrate is larger. Skim the surface if you use sand.
2. Rub the wall sides of the tank with a soft brush. Use a scraper for the rest of the glass
3. Clean the plants and other decorative items. Use a soft brush for plants and decor

Substrate

Layer the bottom of their tank with dark sand substrate. Introduce plants to the foot of their habitat to give them a homely taste. Leaves, similar to their role in the wild, will make the water brown and increase the pH levels. Change the leaves from time to time and place twisted roots on the sub-substrate, too.

Community Tank Mates

As I mentioned earlier, Black Neon Tetras can easily get along with a variety of fish species. They love being around fish from their tetra species, but you can also pair them up with other fish.

Except for certain situations, they never display aggression or other behavior issues while being with other fish species. But avoid placing them with aggressive fish or any large fish that can turn them into its meal.

Here’s a list of some compatible tank mates from their own species, Tetras.

1. Small Freshwater Catfish
2. Chili Rasbora
3. Dwarf Gourami
4. Harlequin Rasbora
5. Celestial Pearl Danio
6. Honey Gourami
7. Rummy Nose Tetra
8. Sparkling Gourami
9. Freshwater Aquarium Nails
10. Neon Tetra

Poor tank mates

Housing your little Neon Tetra with any large or aggressive fish is not certainly a good option. The temperament Black Neon Tetras has is quite pleasant, but not every fish can will align with their nature.

Here are some incompatible tank mates:

1. Freshwater Sharks
2. Most Cichlids
3. Large aggressive fish
4. Nippy fish like Tiger barbs

Breeding

Preparing the groundwork to breed them is pretty simple if the water hardness, acidic conditions, and temperature are gauged accurately. The overall water parameters, a diet composed of live foods, and keeping the tank dim are enough to trigger them to breed (video source).

Other Tetras and Black Neon Tetras are alike in spawning. They need open water to release their eggs and milt.

To encourage the spawning season, prepare a separate breeding tank for the male Neon Tetras and the female Neon Tetras. After setting up their breeding tank, cover the surface with a towel or something else suitable for the purpose and raise the temperature. The temperature should be around 79° F to 80° F.

Feeding them live foods, as well as paying attention to other factors important for activating the spawning conditions, holds great importance.

As discussed earlier in the article, the females look fatten from their abdomens, which shows they are pregnant. The only difference between a pregnant female and a non-pregnant fish is the fulness of their abdomens. The former looks more pronounced from the belly.

You don’t need to have a large spawning tank for them to breed. A 5 to 10-gallon tank is enough for the breeding pair.

Black Neon Tetras are egg layers. In the separate tank, the female needs a spawning site for fry to attach. If you don’t have one, you can create it with fine-leaved plants. As an alternative to fine-leaved plants, get a synthetic analog that is easier to clean.

Also, cover the surface with something to protect the eggs from falling. You will also need to protect them from their parents because of their poor parenting instincts.

The mother fish will lay hundreds of eggs and will attach them to the substrate. Within 20 to 30 hours, the eggs will hatch.

Now comes the baby Neon Tetras. Until they are large enough to eat, they will survive on their egg sac. After that, feed them baby brine shrimp and keep them in a different tank until they grow large enough to further grow among the adult Tetras.

Food and Diet

They are pretty good with almost everything you put in their tank. In the wild, they sustain themselves on small crustaceans, filamentous algae, and invertebrates.

In the aquarium, feeding Black Neon Tetras is quite easy. You can give them brine shrimps, very fine fry food, mosquito larvae, or frozen bloodworms.

To keep your fish healthy, adding some vitamins like Vita Chem into their diet will positively affect their overall growth and activity.

Common Health Problems

Like other tropical fish, Black Neon Tetras are also susceptible to common health problems. They are hardy and can put up with rough conditions, but here are some pathological conditions you will see them fighting with.

Always add them to a fully cycled tank. Black neons are hardy once established, but ammonia or nitrite in a new setup will kill them before you realize something is off.

Ich

Most fish species get infected with Ich due to stress. Larger fish in the tank or not having a home-resembling environment can stress out your Black Neon Tetra.

The symptoms are:

1. Loss of appetite
2. White spots on the gills or other body parts
3. Abnormal hiding behavior

Dropsy

This is another common health problem in tropical fish species.

Symptoms include:

1. Loss of appetite
2. Lethargy
3. Swelling of stomach
4. Unusual floating at the top

Neon Tetra Disease

Your fish is likely to get infected by a disease called Neon tetra Disease. This disease was first found in Neon Tetras. Fish suffering from Ich are more prone to this ailment.

Symptoms are:

1. Cysts
2. Difficulty to swim
3. Segregation from tank mates
4. Curving of the spine

From the first two ailments, Neon Tetras can easily get cured, but there’s no cure for Neon Tetra Disease. To stop it from spreading, separate the infected fish from the healthy ones.

FAQs

Is the Black Neon Tetra Right for You?

Before you add a black neon tetra 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. Black Neon Tetras 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 black neon tetra 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.

What It Is Actually Like Living With Black Neon Tetra

Black neon tetras are calm, steady swimmers that stay in the middle column. They do not dash around frantically or hide in corners. Their movement is smooth and predictable, which adds a sense of calm to any tank.

They look best when viewed from the side at eye level. The iridescent stripe catches light at specific angles, creating a shimmer effect that changes as they swim.

They are one of the least demanding tetras when it comes to feeding. Standard flakes, micro pellets, and occasional frozen food keep them in perfect condition.

In mixed tetra tanks, black neons hold their own without being aggressive. They coexist peacefully with virtually every other small community fish.

How the Black Neon Tetra Compares to Similar Species

Choosing between similar species is tricky. Here’s how the black neon tetra stacks up against some common alternatives.

The black neon tetra 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 black neon tetra or something similar that’s more widely available. The answer usually comes down to three things: tank size, water parameters, and what other fish you’re keeping. If your setup matches what the black neon tetra needs, it’s hard to beat. If not, there are alternatives worth exploring.

Closing Thoughts

Neon tetras are a great choice for any tank, but they is particularly beneficial in planted and community tanks. They are hardy fish that will add color and activity to your tank without disrupting the peace. Have you ever kept black neons before? Let us know your experience in the comments!

The cardinal tetra does not tolerate shortcuts. It needs soft, acidic water or it fades and dies. This is not a beginner tetra with a beginner price tag. It is an intermediate fish that happens to be cheap enough for beginners to kill by the dozen.

Cardinal tetras do not tolerate shortcuts. They need soft water or they fade and die.

What Most Care Guides Get Wrong About Cardinal Tetra

The most common mistake I see with cardinal tetras is keeping too few. Guides will say “minimum 6” and leave it at that. In reality, these fish behave completely differently in a proper group of 8 to 10 or more. Keeping just 3 or 4 often leads to stress, hiding, and fin nipping that wouldn’t happen in a larger school. Another thing most guides miss is how much lighting and decor affect this species. Cardinal Tetras look washed out under bright white LEDs on a light substrate. Dim the lights, add some tannins, use a dark background, and you’ll see colors you didn’t know they had. I’ve also noticed that many care sheets recommend overly broad water parameters. Yes, cardinal tetras are adaptable. But “adaptable” doesn’t mean they’ll thrive in just anything. In my experience, keeping them closer to their natural soft, slightly acidic conditions brings out the best color and longevity.

The Reality of Keeping Cardinal Tetra

Water chemistry makes or breaks this fish. Cardinals thrive in soft, acidic water. If your tap water is hard and alkaline, you either need an RO system or you should pick a different tetra. Trying to keep wild-caught cardinals in pH 7.8 with 15 dGH is not a challenge worth taking. Tank-bred cardinals are more adaptable, but even they do best in softer water.

They die in batches, not individually. When cardinals start declining, you rarely lose just one. The same conditions that stress one fish stress the whole school. If you see one death, check your parameters immediately because more are likely coming if you do not act.

The color difference from neon tetras is dramatic. The red stripe on a cardinal runs the full length of the body. On a neon tetra, it only covers the back half. In person, this difference is obvious and it makes the cardinal significantly more visually impactful. Both are great fish. The cardinal is the showstopper.

Biggest Mistake New Owners Make

Adding them to a brand new tank with hard, alkaline tap water. This kills more cardinals than any disease. The fish slowly decline over 2 to 4 weeks and the keeper assumes they just got a bad batch.

Species Overview

Classification

What is a Cardinal Tetra?

Cardinal tetra is one of the most popular freshwater fish that is excellent for community tanks. They are highly active, social fish with a peaceful nature. They are small fish with slim, slender bodies ideal for a small tank.

Though easy to care for, these species are not easy to breed in captivity. Therefore the chances of breeding cardinal tetras successfully are very thin.

Origin and Habitat

In their natural habitat, cardinal tetra comes from South America, especially the Amazon river. Needless to say, these schooling fish are tropical fish that prefer warm water temperature and soft acidic water. They mostly inhabit the slow-moving waters in Venezuela, Brazil, and Colombia.

Appearance

The Cardinal tetra is a beautiful, vibrant, colorful fish with a reddish brown coloration extending from the mouth, eyes, and tails, covering most of the lower body. Right above this reddish brown line lies a greenish-blue stripe that divides the body. The dorsal and anal fin of Cardinal tetra possess no color, and the body showcases red stripes, longer than the red neon tetra. These longer red stripes are the distinguishing factor between the Cardinal tetra and red neon tetras.

From the mouth and eye to the tail runs a reddish-brown coloration covering most of the lower body. Above that runs a green fluorescent band. The dorsal and anal fins have no color. The male is less thick in the body than the female. This species is not easy to breed. Suitable pairs are picked by observation and kept apart feeding with live food to get them ready.

There is a small, silver area along the ventral surface of the Cardinal tetra with the lower body; bright red. In fact, the name, Cardinal Tetra is derived from this bright red color that resembles the red robes of the Cardinals.

Average Size

The Cardinal tetra is a small freshwater aquarium fish that grows up to 2 inches in length. They occupy the middle level of the tank mostly, thus, remain happy with other fish that are bottom or surface-dwelling.

Lifespan

In their natural habitat, the life expectancy of a Cardinal tetra is very short, i.e, about a year. However, in captivity, they are known to live for around five years or longer, if their requirements are met.

Care

Cardinal tetras are hardy and very easy to care for beginners. However, bear in mind that minor negligence can cause potential damage to your beloved finned friends.

Therefore, it’s recommended to follow this care guide to raise healthy and happy Cardinal tetra in an aquarium.

Here’s a summary of what needs to be followed to care for your Cardinal tetra.

1. Keep them with other fish that are similar or smaller in size to avoid stress and other illnesses.
2. Always aim to provide slightly acidic and very soft water in your aquarium tank.
3. Keep the aquarium clean and hygienic and feed them more live foods than commercial food.
4. Fill your tank with big-leafed plants to help them scatter their eggs while breeding.

Aquarium Setup

The Cardinal tetra is a small tropical fish that need ample room to swim despite its small size. Also, they don’t appreciate cramped living conditions in a tank. Thus, I recommend setting up a tank that is longer rather than taller, such as the wall-mounted aquarium lines.

Also, they are middle dwellers, peaceful, schooling fish. Thus, I suggest keeping them with companions that are bottom-dwelling or surface dwelling.

Tank Size

As mentioned above, despite their small size, Cardinal tetras love free swimming space. Therefore, I suggest a tank size of no less than 10 gallons to accommodate only one or two of them. However, if you’re getting a shoal of Cardinal tetra species or other tetra species with a group of six or more which is recommended, it’s crucial to go for a tank size as big as 20 gallons.

Water Parameters

In the wild, the water is soft and slightly acidic. And to keep cardinal tetras happy, also aim for acidic water.

The ideal pH range for Cardinal tetra is around 4.6 to 6.2. The cardinal tetra is known to tolerate a pH level of up to 7.4. However, I recommend you keep it below 6.

The ideal water temperature for your Cardinal tetra tank is around 73°F to 81°F, thus, replicating the water parameters of their natural environment. Besides, the carbonate and bicarbonate levels in your aquarium tank should be around 2 to 6 KH. Also, the water hardness should exceed 4 dGH.

Filtration and Aeration

Sure, cardinal tetras are small freshwater fish, but they are vulnerable to the toxic elements in the water. For example, nitrates and nitrites. Therefore, setting up a good filtration system is crucial.

Since cardinal tetras are schooling fish, experts advise keeping them in groups. However, many novice aquarists when keeping them in groups underestimate the power of a filter. As a result, uneaten food, fecal matter, and other debris accumulate in the tank and release harmful toxins such as Ammonia. Thus, installing a high-quality filter that adds oxygen and a little movement in the water is highly recommended.

Nonetheless, in my experience, aquarists skip the filter and add many live plants in the aquarium that consume Ammonia and keep the tank oxygenated and less polluted. However, if you’re a complete novice, I don’t suggest skipping the filter as it will lower the maintenance of your tank and keep your fish healthy and happy for long periods. Also, you won’t have to change the water regularly.

Best Aquarium Filter for this type of Fish

You can install canister filters. However, they are not within the budget of in my experience, hobbyists. A more budget-friendly option would be to purchase a hang-on back filter like a Hagen Aquaclear. I strongly recommend putting on a sponge on the intake of the filter so as to not have these tiny fish sucked up by it.

Lighting

In their natural habitat, the cardinal tetras come from warm, slow-moving water with densely vegetated areas. Therefore, the sunlight is filtered by plants.

Thus, I recommend setting up your aquarium lighting to low or moderate levels and adding lots of floating or rooted plants to filter the light.

Aquatic Plants and Decorations

If you plan on breeding cardinal tetra, I cannot emphasize the importance of aquatic plants enough. Plants provide your Cardinal tetras with a hiding space with an open swimming space. I suggest keeping floating plants in the aquarium that provides hiding places for your cardinal tetras.

Substrate

Cardinal tetras are at their best in an environment that mimics their habitat. Thus, going for a muddy substrate or sandy is your perfect bet. If you have a planted tank, you need to a planted tank substrate in order to support the growth of your plants.

Community Tank Mates

Cardinal tetra is a shoaling fish that lives in shallow rivers and prefers to live in a group of at least 6 fish in a 20-gallon tank. However, if you have more room, cardinal tetras would warmly welcome their tank mates. The ideal tank mates for cardinal tetras are:

1. Neon tetra
2. Green neon tetras
3. Ember tetras
4. Black skirt
5. Emperor tetras
6. Zebra Danios
7. Chili Rasbora
8. Dwarf Gouramis
9. Guppies
10. Hatchetfish
11. Mollies
12. Angelfish
13. Small catfish
14. Otocinclus
15. Loaches
16. Dwarf shrimps
17. Snails

I suggest avoiding any aggressive and large fish (Goldfish, aggressive cichlids, etc) that would lead to unnecessary stress to your cardinal tetras.

Breeding

Well, breeding cardinal tetras is a daunting task. You need to follow the water chemistry of Amazon and its subsidiary rivers as close as possible to attain successful breeding. Here is a video below for those who want a visual reference.

For example, the tank water should have low mineral content with slightly acidic water, clean, and soft. The water temperature should be around 73°F to 81°F. Even though cardinal tetras are easy to care for and somewhat low maintenance, however, when it comes to breeding, the situation changes completely. 

In the wild, the water is loaded with natural vegetation that forms a shield for direct sunlight. Thus, in such an environment, cardinal tetras spawn in large numbers. They lay eggs in large numbers. When the eggs hatch, the new fish is protected by nature and have enough food and places to hide.

However, in captivity, the breeding process depends on many factors, such as water hardness and other water parameters. When the requirements are not met, the adult cardinal tetras face difficulty in spawning and hence breeding.

Requirements for a Separate breeding tank

Even if you provide cardinal tetras with the ideal water conditions, they have a habit of eating their own eggs. Thus, to avoid all these problems and overcome the difficulties in the breeding process of cardinal tetras, here are some suggestions.

1. Set up a separate breeding tank when the male tetras and female tetras are ready for spawning
2. In the breeding tank, place the female cardinal tetras in the morning and male tetras in the evening
3. Keep the water parameters optimal and the tank clean. Filter the tank regularly and remove debris, uneaten food, and other particles.
4. Feed cardinal tetras nutritious food to boost their immunity. Increase the proportion of live foods such as brine shrimp and small crustaceans.
5. Maintain the water temperature slightly higher than the normal temperature. 
6. Monitor the eggs carefully after spawning. The eggs of cardinal tetras are extremely photosensitive. Therefore, keep them in the dark
7. Remove the adult cardinal tetras from the tank right after the eggs are laid to protect the eggs from their own parents
8. The fry usually comes out within 24 hours. Keep your tank dimly lit as they are sensitive to light for the first week
9. Feed cardinal tetras fry liquid food. After 2 to 3 days, start feeding them baby brine shrimp and sifted Daphnia
10. The fry of cardinal tetras grow slowly and become adults after 10 weeks
11. Keep the temperature within the recommended range and the tank clean. The color of cardinal tetras fades away if the water conditions are not favorable

The breeding process becomes easy as a breeze if you take care of the water conditions and hygiene of the tank.

Food and Diet

The best thing about raising cardinal tetras is effortless feeding. They are omnivores and opportunistic feeders that even eat plant matter. Thus, you can feed them anything. Dried or flakes food, live and frozen foods with meaty snacks. I don’t recommend feeding them live food regularly as they will refuse flaked or dry food, which is not acceptable. Dry food is loaded with vitamins and is much cheaper and more accessible than live or frozen food. Also, you can avoid many diseases that come with infected live foods.

You should feed your tetras at least twice a day with enough food that they can consume in around 2 minutes. The food that remains in the water after 3 minutes should be instantly removed to maintain tank conditions and avoid fish overfeeding.

Common Health Problems and Diseases

Like other fish, cardinal tetras are also susceptible to certain fish diseases and infections. They can also get neon tetra disease.

Disease

The Neon tetra disease is caused by harmful parasites that spread like a wildfire and are fatal to the fish. When the fish suffers from neon tetra diseases, you should to remove it as soon as possible from the tank and quarantine it as this disease is highly contagious.

Gill Flukes

This disease is also caused by the parasites in which the gills of cardinal tetras serve as a host for fluke and provide it with the nutrition to grow and multiply in big numbers. The common symptoms of gill flukes are:

1. Rubbing the body on the bottom or sides of the tank
2. Rapid, abnormal gill movement
3. Lethargy

Fin Rot

Fin rot disease is caused by harmful toxins such as nitrates, which leads to the loss of tissue from fins, tail, or even the body of cardinal tetras. Therefore, strive to maintain the water conditions of your tank with a proper filtration system and weekly or biweekly water changes. The symptoms of fin rot include:

1. Damaged gills
2. Ulcers on the body
3. Loss of color
4. Loss of appetite

Differences Between Male and Female

They both grow around 2 inches in length. However, the females are rounder than their male counterparts. Also, the male tetras have a small hook present on their anal fins while females lack it.

FAQs

Is the Cardinal Tetra Right for You?

Before you add a cardinal tetra 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. Cardinal Tetras 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 cardinal tetra 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.

What It Is Actually Like Living With Cardinal Tetra

A school of 15+ cardinals in a planted tank with tannin-stained water creates a display that stops people mid-conversation. The blue stripe glows under moderate lighting in ways that photos cannot capture.

They are most active during the first few hours after lights come on. Mid-afternoon they will settle into a more relaxed swimming pattern through the middle of the tank.

Cardinals are not shy once established. After a settling period of a week or two, they own the middle column and school confidently in open water.

Their color shifts slightly with mood and lighting. Under blackwater conditions with warm-toned light, the red deepens to a rich crimson that is absolutely stunning.

How the Cardinal Tetra Compares to Similar Species

Choosing between similar species is tricky. Here’s how the cardinal tetra stacks up against some common alternatives.

Cardinal Tetra vs. Neon Tetra: Both are iconic small tetras with a glowing blue and red stripe, but the neon tetra has red coloring that extends the full length of the body, while the cardinal tetra’s red is limited to the belly. Cardinals are considered slightly more delicate and prefer warmer, softer water. They also will cost more. For most community tanks, either species works beautifully, but if your water is harder or you’re on a budget, the cardinal tetra is the easier pick. Check out our Neon Tetra care guide for a detailed breakdown.

Cardinal Tetra vs. Green Neon Tetra: Both are iconic small tetras with a glowing blue and red stripe, but the green neon tetra has red coloring that extends the full length of the body, while the cardinal tetra’s red is limited to the belly. Cardinals are considered slightly more delicate and prefer warmer, softer water. They also will cost more. For most community tanks, either species works beautifully, but if your water is harder or you’re on a budget, the cardinal tetra is the easier pick. Check out our Green Neon Tetra care guide for a detailed breakdown.

Final Thoughts

Cardinal tetras are exquisite freshwater aquarium fish that add vibrancy and elegance to your home aquarium. However, difficult to breed, they are pretty easy to care for and opportunistic feeders that feed on almost everything.

I recommend quarantining your fish before adding them into your home aquariums since they are being sold in the aquarium trade as wild-caught fish. This would prevent the spread of diseases and illnesses.

Cherry Shrimp tank mates are any fish small and peaceful enough not to eat them. That list is shorter than most guides suggest.

Cherry shrimp are on the menu for most fish. Plants are their survival insurance.

Cherry shrimp (Neocaridina davidi) make fun and fascinating pets that look amazing, especially in a planted aquarium. The problem many aquarists face is that these tiny crustaceans are so difficult to find tank mates for. It seems like just about every fish out there wants to eat these peaceful inverts!

Cherry Shrimp Care – The Basics

Cherry shrimp are very small, delicate creatures that are pretty much at the bottom of the aquarium food chain. The foundation of any good cherry shrimp community tank is providing the perfect conditions for your dwarf shrimp to thrive and even breed.

Let’s take a look at some basic facts about cherry shrimp.

• Scientific name: Neocaridina davidi
• Origin: China
• Adult size: 1-1.6 inches
• Minimum take size: 2 gallons
• Care level: Easy
• Die: Omnivorous
• Temperature: 65-84°F, with about 73°F being ideal
• pH: 6.5-8
• GH: 4-8 dGH
• KH: 3-15 dKH

Choosing Tank Mates For Cherry Shrimp – What You Need To Know

Keeping cherry shrimp with just about any fish is risky. A lot depends on the personality of the fish and even the layout of your tank. Here are some important factors to consider:

Size

There is a simple rule that all experienced fish keepers know, don’t put small fish together with anything big enough to swallow them whole. The same rule applies to dwarf shrimp of course, but it’s not always that simple.

Small size cherry shrimp and babies will be vulnerable to almost all aquarium fish. Some small fish will also pick at the shrimp, so they don’t necessarily need to be able to swallow them whole to do serious damage. The safest bet is to go for small tank mates with very small mouths.

Temperament

Some fish are more aggressive than others. Silvertip tetras, for example, tend to be very nippy fish and they can pick at your shrimp even if they aren’t going to eat them. Bettas and gouramis can also be aggressive towards shrimp in the same way.

Competition

Shrimp are very small creatures and they is easily outcompeted for food sources by larger, faster fish. Even slow-moving tank mates can outcompete shrimp if their numbers are high enough. Bladder snails and ramshorn snails, for example, can multiply pretty quickly in the right conditions!

Baby Safety

Female shrimp keep their eggs safely under their tails instead of laying them in the tank. When the eggs hatch, however, the tiny shrimplets are highly vulnerable to even the smallest fish in freshwater aquariums.

Keeping baby shrimp (shrimplets) safe from tank mates is very difficult. If you plan on breeding your shrimp and getting the best survival rate, a shrimp-only tank is going to be your best bet!

Baby shrimp can survive to adulthood in a community tank, however, the secret is to provide the kind of cover for them to hide and stay safe. Live plants like Java moss that provide plenty of hiding spots are the best options.

Have A Backup Plan!

The number one most important piece of advice when setting up any community aquarium is to have a plan B. A small quarantine tank that holds a few gallons is ideal for moving any troublemakers away from your cherry shrimp and other fish.

All you need is a hood, a small filter, and a heater to complete this setup which can also be used for quarantining new fish, breeding projects, or treating sick livestock.

Best Tank Mates

Now that you know a little more about the basics of red cherry shrimp tank setup and care, I’m sure you can’t wait to find cherry shrimp friends!

Let’s take a look at some of the best tank mates for cherry shrimp. I’ll list out the following important information for each tank mate:

• Scientific name
• Origin
• Adult size
• Minimum tank size
• Care level
• Diet
• Temperature
• pH

Take note of these stats because you’ll need to keep both your cherry shrimp and their tank mates happy. Check out the video above from our YouTube channel. We go into more detail in our blog post below.

Let’s get started!

1. Amano Shrimp

Best Shrimp For Planted Tanks!

Amano Shrimp

Best For Planted Tanks!

When it comes to keeping a healthy planted aquarium, Amano Shrimp are the best. These hard-working crustaceans will dutifully wipe your plants and rockwork clean of algae. Their appetite for different types of algae that can’t be matched by other shrimp breeds!

• Origin: Japan
• Adult size: 2 inches
• Minimum tank size: 10 gallons
• Care level: Easy
• Diet: Omnivore
• Temperature: 60-80°F
• pH: 6-7.6

Have you ever thought about keeping other shrimp species with your cherry shrimp? Amano shrimp are a great choice because they are super peaceful and they do great in similar water parameters.

Amano shrimp are algae eaters which means they need a well-established tank to stay fed. It’s best to add these guys a few months after setting up the tank.

Amano shrimp are not the only other shrimp species that you can keep with cherry shrimp. Ghost shrimp and vampire shrimp are also great options. Just be sure to avoid crystal shrimp because they prefer different water conditions.

2. Thai Mico Crabs

• Scientific name: Limnopilos naiyanetr
• Compatibility: High
• Origin: Thailand
• Adult size: 0.5 inches
• Minimum tank size: 2 gallons
• Care level: Moderate
• Diet: Omnivorous
• Temperature: 72-82°F
• pH: 6.5-8

Dwarf shrimp are not the only awesome crustaceans that you can keep in your tank. Thai micro crabs (video source) are really interesting creatures that you can keep in the same tank with your cherry shrimp.

Thai micro crabs are tiny and shy, but you’ll be happy to watch these little whitish or blueish crabs hanging out in your freshwater aquarium.

3. Aquarium Snails

Best Algae Snail

Horned Nerite Snail

Horned Nerite Snails are excellent algae eaters for planted tanks.

• Scientific name: Varied
• Compatibility: High
• Origin: Varied
• Adult size: 1-2 inches
• Minimum tank size: 5 gallons
• Care level: Easy
• Diet: Omnivorous
• Temperature: 65-82°F
• pH: 6.5-8.5

Almost all freshwater snails go great with shrimp. Snails are great for eating algae and keeping your tank clean too, and they’re really easy to maintain.

Choose your snail species carefully though, some aquarium snails breed out of control. I recommend nerite snails because they look amazing and they can’t breed in your cherry shrimp tank.

4. Otocinclus Catfish

• Scientific name: Otocinclus spp.
• Compatibility: High
• Origin: South America
• Adult size: 2 inches
• Minimum tank size: 10 gallons
• Care level: Easy
• Diet: Algae
• Temperature: 74-79°F
• pH: 6-7.5

Otocinclus catfish are probably the safest fish species that you can keep with cherry shrimp. These nano sucker fish are specialized algae eaters so they’re perfectly safe, even with baby cherry shrimp!

These fish do an amazing job of keeping aquariums clean too, just make sure to add them to mature aquariums so they’ll have enough food to eat.

5. Neon Tetra

• Scientific name: Paracheirodon innesi
• Compatibility: High
• Origin: South America
• Adult size: 0.8-1.2 inches
• Minimum tank size: 10 gallons
• Care level: Easy
• Diet: Omnivore
• Temperature: 70-77 °F
• pH: 6-7

Neon tetras are very peaceful fish with very small mouths. These nano fish are a safe bet with adult cherry shrimp but they will eat baby shrimp if they get the chance, so make sure you provide plenty of cover like Java moss. These brightly colored fish look great with blue velvet shrimp.

6. Ember Tetra

• Scientific name: Hyphessobrycon amandae
• Compatibility: High
• Origin: Brazil
• Adult size: 0.75 inches
• Minimum tank size: 10 gallons
• Care level: Easy
• Diet: Carnivore
• Temperature: 72-77°F
• pH: 5-7

The ember tetra is a very small fish that can make a great tank mate with cherry shrimp. Their bright colors match perfectly with fire red cherry shrimp and other red breeds like the sakura cherry shrimp.

These fish are super peaceful so they will get along with any other tank mates of a similar size. Ember tetras, like neon tetras, are schooling fish so pick up a group of at least 6.

7. Chili Rasbora

• Scientific name: Boraras brigittae
• Compatibility: High
• Origin: Borneo
• Adult size: 0.75 inches
• Minimum tank size: 5 gallons
• Care level: Easy
• Diet: Carnivore
• Temperature: 68-82°F
• pH: 4-7

Chili rasboras are awesome nano fish that can live peacefully with cherry shrimp. They are beautiful little red fish with great black markings. These schooling fish are truly tiny, so they pose no threat to your adult cherry shrimp.

Chili rasboras prefer slightly acidic water so they are going to work best if your pH is between 6.5 and 7. Keep a group of 6 or more of these fish in a heavily planted tank for an awesome nano aquarium.

8. Corydoras Catfish

• Scientific name: Corydoras spp.
• Compatibility: High
• Origin: South America
• Adult size: 1-4 inches
• Minimum tank size: 10-30 gallons
• Care level: Easy
• Diet: Omnivore
• Temperature: 74-80°F
• pH: 7-8

Corydoras catfish are another great tank mate for cherry shrimp. The safest cory catfish are going to be the pygmy cory (C. Pygmaeus) and dwarf cory (C. Hastatus).

These tiny fish are not bottom dwellers like the larger species and tend to hang out in the open water column. Just be sure to buy a nice big school so they can swim around together in the midwater of your tank.

9. Endler’s Livebearer

• Scientific name: Poecilia wingei
• Compatibility: High
• Origin: Venezuela
• Adult size: 1 inch
• Minimum tank size: 10 gallons
• Care level: Easy
• Diet: Omnivore
• Temperature: 64-82°F
• pH: 5.5-8

Endler’s livebearers are similar to guppies but don’t grow quite as large. These awesome colorful fish are very easy to care for and they won’t bother adult shrimp.

Endler’s livebearers breed quickly if you keep males and females in the same tank, however, so be ready to find homes for lots of baby fish! The males are smaller and more colorful than the females so you could keep only males if you want to avoid breeding. They will be pretty territorial though, so keep a nice big group of 6 or more to spread out any conflict.

10. Pencil Fish

• Scientific name: Nannostomus spp.
• Compatability: Moderate
• Origin: South America
• Adult size: 1.5 – 2 inches
• Minimum tank size: 10 gallons
• Care level: Moderate
• Diet: Carnivorous
• Temperature: 72-82°F
• pH: 6-7.4

Pencil fish can also make great tank mates for cherry shrimp. These interesting schooling fish from South America have tiny mouths and they also swim towards the surface of the tank, keeping them out of contact with your cherry shrimp.

There are many great pencil fish species to choose from in the aquarium hobby. Beckford’s pencil fish (N. Beckfordi) is a great option because they are pretty easy to find and care for.

11. Clown Killifish

• Scientific name: Epiplatys annulatus
• Compatability: Moderate
• Origin: West Africa
• Adult size: 1.25 inches
• Minimum tank size: 10 gallons
• Care level: Moderate
• Diet: Carnivore
• Temperature: 68-79°F
• pH: 4-7

Clown killifish make interesting tank mates for cherry shrimp. These tiny fish tend to hang out at the top of the tank while the cherry shrimp are foraging down below on the substrate, so they stay out of each other’s way.

Clown killifish are predators, so they will feed on baby shrimp. Keeping these tank mates together would be safest in a heavily planted tank with loads of cover. You should always have a solid backup plan, however, especially if you keep higher-graded shrimp.

12. Kuhli Loach

• Scientific name: Pangio kuhlii/ semicincta
• Origin: Southeast Asia
• Adult size: 3-4 inches
• Minimum tank size: 15 gallons
• Care level: Easy
• Diet: Carnivore
• Temperature: 70-79°F
• pH: 3.5-7

Kuhli loaches are one of my favorite nano bottom dwellers. These strange fish have beautiful markings and they’re really peaceful too. They do a great job of cleaning up leftover food at the bottom of the tank, but they are pretty shy during the daytime, so they’re not the best display fish.

Tank Mates To Avoid

Unfortunately, the list of fish that you can’t keep with shrimp is much longer than the list of fish that you can. Of course, you should avoid any large or predatory fish, but some popular aquarium fish should also be avoided.

Here are 5 popular types of fish that don’t go well with cherry shrimps.

1. Goldfish

Goldfish love to snack on red cherry shrimp. It is possible to keep them together but only if you don’t mind losing shrimp to your goldfish.

Common goldfish and other fast swimming breeds like comets are a definite no-no, but slow-moving fancy goldfish might not eat all of your cherry shrimps.

2. Cichlids

Cichlids are definitely not safe tank mates for cherry shrimp. Even the species that don’t eat invertebrates is aggressive and kill your red cherry shrimp.

3. Rainbowfish

Rainbowfish have been known to make pretty short work of even adult shrimps. This is one fish you should definitely keep out of your cherry shrimp tank!

4. Betta Fish

Some betta fish don’t seem to care about sharing a tank with cherry shrimp. Others will absolutely decimate your shrimp colony in no time at all!

This is one pairing that is best to avoid. If you must try it, a slow-moving betta with large fins is going to be your safest bet.

5. Dwarf Cichlids

You probably weren’t surprised to learn that larger cichlids are not peaceful tank mates for cherry shrimp. Unfortunately, the smallest species like rams and apistos will also peck at your cherry shrimp.

Community Tank Setup

Read this section to learn how to create an awesome cherry shrimp community tank.

Introducing Tank Mates

It is best to introduce your cherry shrimp long before you add their tank mates. This will give them a chance to settle in and get comfortable in the aquarium. If all goes well, they might even start breeding, which could make up for any losses from hungry tank mates.

Tank Size

Cherry shrimp is kept in tanks as small as 2 gallons, but if you’re looking to set up a community tank, I would suggest looking at a 10 to 15-gallon tank at a minimum. This will allow you to keep a nice school of something like neon tetras, a few nerite snails, and maybe even a few kuhli loaches if you have good filtration.

The absolute minimum tank size for a community tank with fish would be a 5-gallon setup with a small school of chili rasboras and some red cherry shrimp.

Heating & Filtration

You’re going to need a small heater to keep your water temperature stable in the cherry shrimp’s preferred range. Take care to choose a heater model that matches your tank size and use a thermometer to easily monitor the water temperature in your aquarium.

Some people have managed to keep shrimp without a filter, but this is a bad idea if you ask me, especially if you are going to be keeping fish with your shrimp. A sponge filter, an air pump, and some tubing are all you will need.

For larger community tanks, you can also look at a hang-on back or canister filter. Just make sure you cover your filter’s water intake to prevent any curious shrimp from getting sucked in.

Maintenance & Testing

Cherry shrimp require excellent water quality with zero ammonia and nitrite levels. Keeping your cherry shrimp (and their tank mates) healthy in the long run is going to require regular maintenance and water testing.

A test kit is very important for monitoring changes in your water chemistry over time. In fact, you’ll need to test your water before you even add your cherry shrimp to confirm that your water parameters are good for them.

Pick up a test kit that can measure the following parameters:

• pH
• GH
• KH
• Ammonia
• Nitrite
• Nitrate

Perform a partial water change when your nitrate levels reach about 20 ppm. They can go a little over this for short periods but it will start getting dangerous for your pets.

Nitrate levels will increase at about the same rate every week if you have the same number of shrimps and livestock, and provide the same amount of food. With regular testing, you can work out the ideal maintenance schedule for your aquarium.

Substrate & Decorations

Red cherry shrimp is kept over pretty much any aquarium-safe substrate for freshwater tanks. Gravel or sand make great choices for lightly planted tanks but a complete aquarium soil would be a better choice for a heavily planted aquascape.

Any ornament or decoration that is designed for aquarium use will provide a great place for cherry shrimp to hide and forage. Natural materials like driftwood and lava rock work great too.

Live Plants For Your Freshwater Shrimp Tank

Live plants and cherry shrimp are a perfect combination. Plants provide the shrimp with excellent foraging grounds, as well as cover for the baby shrimp to hide in.

Both female and male cherry shrimp molt about once a month. The hiding spots provided by the plants will also keep them safe as their shell hardens.

Plants also oxygenate the water and improve water quality for your shrimp and their tank mates by soaking up excess nitrates. Live plants also look amazing, and they’re great fun to grow too! Java moss is the go-to plant for shrimp keepers but dwarf hair grass is also a great option.

The following other plant species make great choices for cherry shrimp community tanks:

• Java fern
• Anubias
• Water wisteria
• Water lettuce

Feeding & Diet

Cherry shrimp will happily munch on uneaten food, but you should also provide them with a well-balanced diet of blanched vegetables and shrimp pellets. There are some excellent shrimp food products on the market like Dennerle’s Shrimp King Food that really enhances their colors.

My Pick

Dennerle Shrimp King Food
