The Wakin Goldfish is not a beginner fish. It is a cold-water species that produces enormous waste, needs real filtration, and outgrows most tanks within a year. I have kept goldfish in ponds and large tanks for over 25 years. Here is the honest care guide most people need before buying one.

A goldfish in a bowl is not thriving. It is slowly suffocating.

Goldfish live 10 to 15 years, sometimes longer. This is a decade-long commitment to large water volumes, heavy filtration, and consistent maintenance.

A goldfish kept properly is more impressive than most tropical fish. The problem is almost nobody keeps them properly.

The Wakin goldfish is one of the oldest domestic goldfish varieties still kept today. And one of the most overlooked by western hobbyists. I’ve covered dozens of goldfish types over the years on our channel, and the Wakin always surprises people who’ve only seen the slow-moving, round-bodied fancy varieties. It has a sleek body like a common goldfish but with a distinctive double tail and often stunning coloration. After 25 years in this hobby, one thing I always make clear: don’t mix Wakin with fancy goldfish. They’re fast, competitive swimmers that will outcompete slower varieties for food every time. This guide covers everything you need to keep Wakin goldfish thriving. Whether in a pond or a large aquarium.

What Most Care Guides Get Wrong About Wakin Goldfish The Traditional Japanese Variety Worth Knowing

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

The Reality of Keeping Wakin Goldfish

Tank size requirements are not negotiable. A single fancy goldfish needs at minimum 20 gallons. A single-tail variety like a comet needs 40 gallons minimum, and realistically belongs in a pond. The one-gallon-per-inch rule does not apply to goldfish.

Filtration needs to be oversized. Goldfish produce more ammonia than tropical fish of the same size. Your filter should be rated for at least double your actual tank volume. A 40-gallon tank with goldfish needs filtration rated for 75 to 100 gallons.

They are cold-water fish that do not need heaters. Goldfish thrive between 65 and 72 degrees. Putting them in a heated tropical tank stresses them and shortens their lifespan. Room temperature water is fine for most homes.

Biggest Mistake New Owners Make

Putting a goldfish in a small bowl or tank without filtration. Goldfish produce massive amounts of waste. Without proper filtration, ammonia levels spike within days and the fish suffers organ damage long before it shows visible symptoms.

Expert Take

The best goldfish keepers I know run heavy filtration and do large weekly water changes. There is no shortcut or trick that replaces those two fundamentals.

A Brief Overview of the Wakin Goldfish

Classification

Origins and Habitat

Like many other goldfish varieties, the wakin was first bred artificially in Japan in the early 16th century. In its early days, the wakin was a highly prized Japanese goldfish, and only available to the wealthy.

, aquarists agree that most of the fancy goldfish breeds we know today originated from mutations in the wakin goldfish.

Like all other goldfish, the wakin is descended from the Chinese gibel carp¹.

What Does Wakin Goldfish Look Like?

Similar to common goldfish (picture source), wakin goldfish are physically characterized by a slender and long body shape with no compression. They are classified as a lean bodied or slim-bodied goldfish. These types of goldfish are more atheltic and make for a more sturdy goldfish than other goldfish.

You will also know wakins by their split tail. However, unlike fancy double-tailed goldfish, these fish have long and flowing double tail. Their caudal fin, which is short, resembles more of a fantail shape. 

Every wakin goldfish has a unique pattern on its body. In terms of coloration, they come in a wide variety, although they are mainly sought in white, red, or a combination of the two. Additionally, you might find rare colors like calico, yellow, orange and brown, but the rarer the color, the higher the price tag is likely to be.

And speaking of variations, you might also find the “watonai” variation of wakins, who have flowing tails.

• How Big are Wakin Goldfish?Add ImageAt a maximum length of 18 inches, wakin goldfish are some of the largest breeds of goldfish you’ll find. You’re more likely to see them grow to this size if you locate them in a pond instead of in a tank. 
• How Long Do Wakin Goldfish Live?Add ImageThe average Wakin goldfish can live up to 10 to 15 years, with some exceptions. Those who are carefully looked after can thrive for as long as 20 years!

Temperament and Activity Level

Wakin goldfish are fast and lively fish who enjoy exploring their surroundings. They are mainly peaceful freshwater fish, able to coexist peacefully with most other community fish. That said, you should avoid putting them together with fancy goldfish, since the latter are slow swimmers. As such, they’ll have to compete for access to food.

Wakin goldfish are also well-loved for their friendly and curious nature. In fact, once you start feeding them regularly, you’ll start to notice how they rush to the surface of the pond or tank to greet you when feeding time is due.

What are Good Tank Mates?

Great Tank Mates

As fast swimmers, these pet fish are best kept with other fast species such as:

• Koi Fish
• Shubunkin Goldfish
• Comet Goldfish

Besides goldfish, apple snails, ghost shrimps, African dwarf frogs, rosy barbs, and weather loaches.

Fish Species to Avoid

, the Wakin goldfish are friendly and playful with most other community fish. However, there are certain fish that don’t get along with them. For instance, you should avoid housing them with aquarium fish species like fancy goldfish as they are slow swimmers and therefore, at a disadvantage during feeding time. You also shouldn’t choose aggressive tank mates for the these fish, such as cichlids. 

Just got yourself or considering a Wakin Goldfish? If so, this article about Wakin Goldfish Care will answer all your questions!

The vivid color, attractive double tail and friendly, curious temperament of the Wakin goldfish (carassius auratus) has led to an increase in its popularity in recent years. Originating in Japan like most other wild carp descended fish, it was the original prototype, of sorts, of many other fancy goldfish breeds.

Wakin goldfish are a good choice for aquatic pet lovers since they’re not difficult to take care of. Although they are best brought up in a pond, they can also be housed in aquariums. With the right care guidelines, of course.

What Do They Eat?

The Waking Goldfish breed is omnivorous. This means that giving them high quality fish food and a varied diet they need is easy, and you can feed them most low-fat foods.

You can give them flakes or pellets, but as always, these should not be their only nutrition source. Instead, you should aim to mix it up by introducing vegetables such as lettuce, broccoli, cabbage and shelled peas, and occasionally, chunks of fruits like strawberries and grapes. Also, if you keep them in an aquarium with live plants, don’t be surprised if they start grazing on them.

Of course, you should always be cautious about overfeeding them, because doing so can lead to the development of one or more of the digestive conditions or swim bladder problems.

What About Live Foods?

Brine shrimp, Tubifex worms, blackworms, bloodworms, mosquito larvae, etc. Make good live foods for these fish. Freeze dried and frozen sources of protein will also work.

How Much and How Often to Feed

A proper diet is very important for the well-being of your goldfish. Feed them too little and they will fall sick, feed them too much and they will have buoyancy problems.

The Wakin fish are omnivores which means they can feast on plant and animal matter. While basic store-bought pellets and flakes are a good source of nutrition, try to bring new variations of food. For example, try to drop some lettuce or diced grapes once a week or so and watch how your fish react to it.

When you’re buying fish food, try to get a mixture of both plant and animal-based varieties. Also, you should choose pellets that sink to the floor rather thank floating on the surface. Goldfish like searching for food at the base of the tank and with variation in the pellets, they won’t get bored.

You should feed them no more than twice daily and no more than what they can finish off within 3-4 minutes. Remove any leftovers from the water to ensure that the water remains inhabitable.

Tank Requirements (Care)

Here’s what to keep in mind when setting up your wakin tank.

Tank Size

Wakin fish can grow quite large and therefore need a lot of room to live freely. A large body also means more waste released into the aquarium. 

With this in mind, at least a 30 gallon tank is required to house one of these guys, along with an additional 10 gallons of water for each new fish. But there are no limits: the larger the aquarium size, the better. To maximize their happiness and lifespan, outdoor ponds are the best place for a Wakin. You can see a great example of a wakin goldfish tank below by C Lifestyle.

Tank Setup

There are some basic elements your tank must have in order for your Wakins to live and thrive. 

Temperature

Wakins prefer to live and thrive in cold water; they should be placed in unheated tanks. The ideal water temperature range for them is 65 to 72 degrees F. 

pH

Maintain a neutral pH for them between 6.0 and 8.0.

Ammonia and Nitrate

Ammonia and nitrate levels should be kept at 0.

Substrate

Large, smooth gravel is a good substrate or a fine sandy substrate is best for Wakin goldfish. This is because goldfish love scouring around, they might mistake gravel for food. The wrong gravel size is accidentally shallowed by your goldfish. Caribsea sand is great for goldfish.

Ideal For Goldfish

Caribsea Super Naturals Sand

This sand by Caribsea is perfect for supporting the foraging habit of goldfish. Also works with bottom feeders and discus fish.

Decor

Using plastic plants along with certain moss types will enhance the look of your aquarium. You can add large stones and small sticks as well to replicate a pond and give your fish plenty of options to play.

Plants

Keeping natural vegetation is difficult when it comes to wakin, who love to eat plants. More active ones might even uproot plants. Moreover, many plants won’t survive in the colder temperatures that wakins like. Knowing this, here are several plants that can take the punishment of these fish or may be ignored entirely:

• Java Fern
• Anubias
• Water Sprite
• Java Moss

If you do not want to deal with the hassle artificial plants is advised. In large commercial size ponds, plants are often omitted

Filtration

To deal with the large amounts of goldfish waste, go with a filtration system meant for large tanks. It’s also advised to get a filtration system with a larger tank capacity than what your setup has. A large power filter is minimum for a Wakin in a aquarium. For ponds, consider a waterfall style filtration system. Large ponds over 1500 gallons will often consider bead filtration for maximum biological filtration.

Since these fish are large and produce a lot of waste, consider a high end biological media like biohome.

How to Breed

We have certain pointers for those of you who are particularly interested in creating your own Wakin ecosystem. 

To push your mating, you must first replicate the natural changes they go through in a pond. Firstly, since they mate during spring, dropping the water temperature to 60 or 65 degrees F will signal the fish to procreate.

You must offer the fish adequate natural vegetation such as the Java moss in order to create suitable egg laying zones. You can also look for artificial spawning mops which do the same job as the moss. You should see fry within 48-72 hours of eggs being laid.

Note that in larger ponds, Wakin Goldfish breed regularly. If you don’t want an overflowing pond, you’ll have to make regular checks. Larger fish like Koi will eat baby fry.

Health and Disease

The best way to keep your fish healthy is with great filtration and a quality diet. Prevention is the best remedy when it comes to health. If you are wondering if your fish is unhealthy, there are some pointers to help.

Signs of Good Health

A healthy wakin is one that retains its friendly, lively and curious nature. You will see it frequently dipping in and out of tank and pond decorations, swimming swiftly and actively, and eating large amounts of food in short amounts of time.

Signs of Poor Health and Treatment

Unfortunately, like all goldfish varieties, wakins are also susceptible to freshwater fish diseases like ich, fin rot, bacterial infections, fluke, etc. The article I linked to contains a wealth of information on how to identify and cure many common diseases you may come across. Common signs of an ill fish would be:

• Rapid breathing
• Flashing or scratching rocks/gravel
• White and stringy poop
• Red marks and ulcers
• Torn or clamped fins
• White spots (not to be confused with mating white spots of goldfish who are breeding)

Wakins are less susceptible to bloat and other diseases that plague fancy goldfish.

Where to Buy (And Cost)

You can find them for sale online and at many aquarium stores. The main issue you will run into when shopping locally is the quality of Wakins. They are classified as beginner fish and not kept in good conditions. The best place to purchase in my mind is from a garden retailer who specializes in pond fish. Wakin goldfish cost more for at these retailers, but they are of superior quality.

My favorite of these are NextDayKoi. They offer a variety of quality goldfish that work well in ponds and larger aquariums. You won’t be disappointed ordering from them!

Jewel cichlids are one of those fish where the name really does justice to the animal. The iridescent red and blue coloration on a healthy specimen is genuinely stunning. I’ve kept them and they’re hardy, bold fish with a lot of personality. The one thing I always emphasize: they’re aggressive, especially during breeding, and tankmate selection requires real thought or you’ll have problems.

If you’ve been researching different species of cichlids, the jewel cichlid may, quite understandably, have caught your eye. Now, despite its undeniable beauty, the jewel cichlid gets a bad rap due to its semi-aggressive temperament.

For many aquarists who wish to maintain a peaceful community tank, adding a jewel cichlid will not be worth it. However, keeping jewel cichlids is not only fun and rewarding, it’s also a great way to liven up your aquarium. Although their temperament will pose a problem to novice aquarists, the jewel cichlid is a worthwhile pet.

Wondering whether a jewel cichlid is worth putting in your home aquarium? Let our jewel cichlid care guide help you decide.

Species Overview

Origins and Habitat

The jewel cichlid Hemichromis bimaculatus originates in West Africa. This is where the fish inhabit richly vegetated freshwater bodies like streams, rivers, and lakes. Jewel cichlids have also been documented in some parts of North Africa.

Because these water bodies are teeming with other cichlids and don’t offer a wide variety of sustenance, they are very competitive habitats. This explains why these jewel fish are naturally aggressive and territorial.

What Does the they Look Like?

The coloration of the jewel cichlid species varies widely. You’ll find them mostly in a bright orange-tinted red with vibrant white spots (this is the blood red jewel cichlid), but many are also colored purple with contrasting greenish spots (green jewel fish).

This color will be intensified during the breeding season. During this time, you’ll also notice a longer ventral, anal, and dorsal fin. Some say that male cichlids have a brighter coloration than their female counterparts. 

Temperament and Activity Level

The hemichromis bimaculatus is recognizable by its aggressive behavior. Particularly when it is stressed or underfed, a jewelfish is more likely to lash out and attack his/her tank mates. Breeding season is when the fish reaches the height of its aggression.

This will all sound very scary, but for the committed aquarist, it’s actually not that difficult to ensure a stress-free environment for this freshwater fish. As long as tank requirements are strictly maintained. The best thing to curb aggression is space and lots of shelter. If you have a small tank, with lots of fish, and no shelter, your Jewel Cichlids will be more aggressive as they fight to claim limited territory.

, your jewel cichlid fish will be seen flitting back and forth across the water. They are also very active fish who like to dig at their substrate, looking for food.

Jewel cichlids are also monogamous, which means they form a breeding pair for life. If your jewel fish are in a pair, don’t be surprised to see them together most of the time! 

What are Good Tankmates?

It will seem like a bad idea to include any tank mates for your jewelfish, fin nippers as they are. Well, you should listen to your instincts. Don’t put them in a community tank. These freshwater fish are best off in a species only or cichlid tank.  

Good Tank Mates

Despite their bad reputation, some jewelfish can, in fact, cohabit peacefully with certain other semi-aggressive species. Accordingly, here are some fish that will make acceptable mates for your jewelfish.

• Clown loaches
• Plecos
• Electric blue acaras
• Redtail shark
• Syndontis catfish
• Scavenger catfish
• Leopard bullfish

Jewel cichlids are one of the most aggressive fish you will ever keep relative to their size. They will terrorize tank mates, destroy aquascapes, and turn a peaceful community tank into a war zone overnight. When breeding, their aggression doubles. I have kept these for years and the number one mistake I see is people treating them like a regular community fish. They are not.

The Reality of Keeping How to Care for a Jewel Cichlid in Your Home Aquarium

The aggression reputation is earned but misunderstood. How to Care for a Jewel Cichlid in Your Home Aquarium is not randomly violent. It is territorial, and territory disputes in a poorly planned tank look like chaos.

Group size controls behavior. Keep too few and you get a bully. Keep enough and aggression spreads out. There is a threshold, and missing it ruins the tank.

Most problems are stocking problems. The fish is not the issue. The tank plan is the issue.

Biggest Mistake New How to Care for a Jewel Cichlid in Your Home Aquarium Owners Make

Keeping too few. A small group of How to Care for a Jewel Cichlid in Your Home Aquarium creates a hierarchy where the bottom fish gets destroyed. The solution is not fewer fish. It is more fish to spread aggression.

Expert Take

Stock heavily, filter aggressively, and provide sight breaks throughout the tank. How to Care for a Jewel Cichlid in Your Home Aquarium is manageable when you control the environment. Let the environment control itself and this fish exposes every weakness.

Fish Species to Avoid

When selecting home aquarium tank mates for your jewel cichlid, it’s best to avoid all fish species if you can, except a few semi-aggressive fish mentioned above.

In particular, peaceful aquarium fish species (for example, any goldfish species) should be avoided at all costs, as your jewelfish will harm them and will even eat or kill them. MBunas and Rift Lake Cichlids should be avoided as they are likely to be attacked and killed. 

What Do Jewelfish Eat?

Feeding jewel cichlids is fairly easy. As omnivorous freshwater fish, jewel fish will readily eat pellets, flake food, and live food as well.

You should aim to provide as balanced a diet as possible. This means mixing and matching different food types. You can also consider giving them vegetables such as lettuce leaves and spirulina. Frozen foods are alright once a week. If feeding pellets or flakes, consider one that contains probiotics like the Cobalt Aquatics line.

What about Live Foods?

Bloodworms, white worms, tubifex, and frozen baby brine shrimp are great live foods for jewel cichlids. Limit providing live foods to once a week.

How Much and How Often to Feed

You should aim to feed your jewel cichlids at least twice a day. Be careful not to overfeed them, however, and don’t confuse their voracious eating for constant hunger.

Feeding your jewel fish properly is crucial if you want them to retain their vivid coloration.

How to Set Up Your Fish Tank

Recreating the Africa habitat or breeding conditions of the jewelfish is not too difficult. Here’s all you need to know about how to set up the tank of your jewelfish.

 Tank Size

For one pair of jewel cichlids, a tank size of at least 30 gallons is required. For each new pair, add 20 gallons. If you put them in a community aquarium (not recommended), provide a tank divider. When your Jewel Cichlids are in breeding mode, consider removing other tank mates if your tank is on the small side. They are known for taking over 30 and 40 gallon tanks!

Substrate

A sandy substrate is best for these fish as they love to dig. Anything sharper will injure them.

Decor

Decorations are a necessity when rearing jewel fish, who are territorial and love to claim their own space. Provide rocks and aim to create cave-like conditions. Rocks with holes or caves are ideal to provide shelter.

Plants

These fish are curious and active fish who love to dig. So, they will get in the way of your aquarium plants thriving unless the plants are protected by rocks and such. Floating plants and column feeders like Anubias Nana and Java Fern would be good examples of plants that could work.

Water Quality

Here are the water conditions you need to ensure for your jewel cichlids

Filtration

Provide adequate filtration for your jewel cichlids to ensure that they can enjoy a water flow mimicking the currents of the streams and rivers they’re used to. They are particularly hardy. They do well with your standard power filter. 

Water Parameters

Maintain these water conditions in your home tank to ensure a healthy environment for your jewelfish.

• Water Temperature: 70°F to 74°F
• pH Range: 7 to 7.5
• Hardness Range: Not above 12 dGH
• Water Movement: Moderate to strong

Aquarium Maintenance

Besides ensuring the proper parameters for your cichlid aquarium, conduct regular water changes of 25% – 40%. Remember, the goal is to reduce your jewelfish’s aggression. Otherwise, their lifespan will be shortened.

How to Breed?

Breeding this species in tanks is relatively easy once you can determine their sex. As they are monogamous, cichlids form pairs quickly and easily during mating season, and once they are parents, they will stick together.

Breeding Tank

You can isolate your cichlid pair in a breeding aquarium, but it’s not necessary if you have just one pair. Gradually raise the water temperature from their regular temperature by a few degrees every day until you reach 80° to 82° F (or 26.7° – 27.8° C).

Breeding Behavior

When the male is ready, his color will become very vibrant, and he will become very aggressive. Like other cichlid species, the male will chase the female about the tank for a little bit until she lays eggs.

Once she’s ready, the female will search for the right place to lay her eggs. She will likely settle on a flat surface, typically a flat-faced rock. She will produce up to 500 eggs.

After Breeding

Once the eggs are fertilized, they will hatch within 2 to 4 days. After hatching, the jewelfish parents will help each other move their kids to a different part of the aquarium. During this time, the parents will be excessively aggressive in order to defend their young fish. 

Feeding Fry

Let the fry absorb the remainder of the egg yolk in the first few days. Afterward, feed them crushed flakes and mashed pellets. Don’t be distressed if the new parents eat some of their offspring. 

Health and Disease

Your jewel cichlid is, unfortunately, prone to the illnesses most freshwater cichlids are prone to. Here’s how to tell whether your jewelfish is healthy or needs care. 

Signs of Health

A healthy jewelfish is a happy one. A happy jewelfish is playful and active (is interpreted as aggression), burrowing in the substrate or flitting about their aquarium. Most significantly, healthy jewelfish retains its vibrant coloration. 

Signs of Ill Health

Here’s a list of several common issues you may come across

•  When a jewelfish is highly stressed, ill, or underfed, it will very likely lose its color. This is one of the most easily seen warning signs of this fish.
• Swelling, loss of appetite, rapid breathing, and differently colored feces are all symptoms of Malawi bloat, a condition that mostly affects African cichlids.
• Notice an indentation in the head of your jewel cichlid? He/she is suffering from hexamita, also known as “hole in the head” disease.
• Look out for ich, which manifests in symptoms like lethargy, loss of appetite, and restless behavior, but most importantly, white spots on the body of the fish.
• Labored breathing and a loss of color might indicate gill flukes.

All of these conditions are covered in our freshwater fish diseases post.

Common Health Issues and Treatment

One of the easiest ways to ensure that your jewel fish is healthy is to provide the required tank parameters with care. Feed them regularly, don’t overfeed, and provide a varied diet. This will keep most illnesses at bay.

Here’s how to deal with other diseases that will come up:

• If you think your jewelfish is suffering from Malawi bloat, act quickly. Change the tank’s water and introduce a dose of Metronidazole. However, know that Malawi bloat is a condition that quickly turns fatal, so don’t blame yourself if something goes wrong.
• Administer the same treatments for ich as you would for other cichlids: increased tank temperature, salt baths, potassium permanganate, acriflavine, and malachite green.
• If you suspect your fish is suffering from gill flukes, use Praziquantel.

Where to Buy?

Compared to other cichlid breeds, the jewelfish is a little harder to buy in brick-and-mortar pet shops. They will also be a little more expensive. If you cannot find them locally, try using an online fish store. Often times, their guarantee will be superior to what you can find locally.

Frequently Asked Questions

The story of Ranchu Goldfish (Carassius auratus) begins in ancient Japan, unlike other fancy goldfish that began in ancient China. They were developed from Chinese Lionhead Goldfish by skilled Japanese breeders. Today, modern day Ranchu Goldfish is found almost anywhere in the world, not just in China or Japan.

Ranchu’s aren’t wild fish, so we must look at their ancestors to learn about their natural habitat.

Like any other goldfish, they descended from an old species of wild carp, known commonly as the Gibel Carp, Silver Prussian carp, or simply Prussian Carp.

These wild carp thrive in slow-moving, slightly cold waters of ponds, lakes, and rivers. Ranchus also prefer similar water conditions and share a lot of traits with Prussian Carp and other goldfish.

What Does Ranchu Goldfish Look like?

It’s quite easy to identify Ranchu Goldfish as they have a rather unusual head growth, an egg-shaped body with a deeper belly, and a horizontally spreading caudal (tail) fin. Looking from the top view, they look a lot like moving worms when swimming. That’s where the name “Ranchu” comes from (which literally means “dutch worm” in Japanense).

Another striking feature of the Ranchu goldfish species is that they don’t have any dorsal fin, much like their Lionhead counterpart. However, Ranchus come with arched backs, unlike the flat backs of Lionhead specimens. Initially bred for top view, they look just as impressive when viewed from the sides nowadays.

They are available in a wide variety of colors, ranging from red, white, orange, blue to bi-colors like red-and-white, black and red, black and white, etc. Their scales is metallic, matte, or nacreous. So, a couple of differently-colored Ranchus will make your aquarium colorful and lively! Black ranchu goldfish are one of my personal favorites.

These fish are comparatively more delicate than other goldfish because of their unique anatomy. So, they are probably not the best option for beginner aquarists. Overall, the beautiful appearance and the unique swimming style of the Ranchu goldfish make them the perfect candidate for any goldfish aquarium.  

The rounded body and the lack of dorsal fin reduce the amount of control Ranchus have over their body when swimming. So, they can’t swim as efficiently as others. Swimming is more tiring for them as well, as you will often see them moving slowly and resting now and then to regain energy. Moreover, the wen or the head growth covers their eyes and makes it harder for them to see.

As a result, Ranchus aren’t good at competing for food. In a tank with fast swimmers and aggressive fish, they will be unable to feed and thrive. The Ranchu goldfish cannot tolerate pollution at all. They will be quick to pick up diseases if the water isn’t clean enough.

Thanks to their rounded body shape, they are highly vulnerable to swim bladder disease. Furthermore, the wen can easily get infected. If you don’t keep a Ranchu goldfish in a well-maintained fish tank with a high-quality aquarium filter, they won’t thrive. It doesn’t take much to stress them out and put them into shock. Their care requirements are much higher than others, so make sure to be extra careful and put more effort.

Brine shrimp, Daphnia, tubifex worms, blood worms, black worms, etc., are some of the most suitable foods for Ranchus. You should minimize the use of live foods as they often contain bacteria and parasites that can make them sick. Ranchus take longer to feed as they have poor vision due to their head growth. You will have to feed them several times a day but remember not to overfeed.

A favorite food staple is soaked pellets or freeze fried food supplemented with vita-chem. This is a great way to add much needed nutrients to common foods. Probiotics are also becoming more common place with food manufacturers with Companies like Cobalt leading the charge.

Can They Live Alone?

The Ranchu, like any other goldfish, can live a long life in solitude. This breed of fish doesn’t mind living alone as long as they get enough food and decent water quality.  However, they are social animals, and they can benefit from social interaction. Ranchus love playing around with other fish as they enjoy companionship.

They love being social in groups. In fact, check out super-cute video of Ranchu goldfish playing football (As reported by the South China Morning Post) to see how fun they is to have around.

They will be visibly happier if you keep them together with other tank mates that won’t compete with them or harass them. So, it’s better to introduce similar types of fish in a Ranchu aquarium if you want the best for them. They do great in an all goldfish tank full of other fancy goldfish varieties.

How Big Can They Grow? What Tank Size Is Right for Them?

Fancy fish like the Ranchu Goldfish are developed to impress you with their shapes, not their sizes. With that being said, the average length of adult Ranchus is around 5”. However, under the right water conditions, they can grow even larger, up to 8 inches!

Learning the size is important because it determines what the tank size that houses them should be. You must make sure to provide them enough room where they can swim freely. In general, the minimum requirement for housing one full-grown Ranchu is 20 gallons.

However, you should start with 20-30 gallons if you want to ensure maximum comfort for your prized fish. Increase the tank size by 10-gallons every time you bring a new fish into the tank. Larger tanks are recommended because that will provide more space for them to swim, and you won’t have to deal with water changes as frequently.

Taking care of Ranchus will undoubtedly pay off. Even though these fish have low tolerance, they will stay healthy and active for a long time as long as you provide for them.

Additionally, you should keep them under constant monitoring. Look for any signs of diseases or discomfort. Perform water changes as often as required. If you notice any difference in their bodies, take action quickly to prevent them from suffering or dying.

Are They Aggressive?

The Ranchu Goldfish is anything but aggressive. They have an incredibly peaceful temperament, and they are rather friendly and cheerful. Their unique structure prevents them from being violent, anyway. For instance, they can’t swim all that fast and tire out pretty easily. They can’t see clearly with their eyes, often due to the growth in their heads. You won’t see them fighting other fish for food because they aren’t equipped to compete.

However, Ranchus do enjoy foraging for food. Make sure not to choose aggressive fishes as their tank mates if you don’t want your goldfish to struggle for survival and fail. They get along pretty well with other similarly morphed goldfish. You can feel free to house them together in an aquarium. Rest assured, they will not transform your tank into the Colosseum and fight each other to death!

How Much Do They Cost?

The price may also vary depending on factors like the size, source, age, etc. In general, you should be able to get your hands on one of them for 5 to 25 dollars from any local pet store or local breeders. However Japan’s “King of Goldfish” has garnered a lot of popularity over the decades with its fancy appearance. Ranchus are prized by many aquarists all over the world, and they are definitely in demand.

The most expensive Ranchus will be shipped directly from Japan or China. These are the most prized of all Ranchus and earn their moniker of “King of Goldfish. These types of Ranchus will easily commander prices of over $50 and can get much more expensive! Importing is how you obtain Ranchu Goldfish developed for competing in various Japanese shows. The video below by hendrink Nursalim shows a competition level Ranchu competing in Aquarama in 2011.

Competition Ranchu Goldfish tend to have more defining features, and their price can range from hundreds to thousands of dollars! You don’t need them unless you’re in the Ranchu Goldfish Enthusiasts category and planning to win one of those competitions. You will have to spend quite some money taking care of these types of goldfish, which you should consider.

No matter what type of fish you get, you must invest in creating and maintaining a proper diet plan for keeping them healthy. Rest assured, they are definitely worth the price.

Tank Requirement

If you’re a goldfish enthusiast, chances are you’ve already got a fancy goldfish aquarium. It might just be the perfect one for the king of goldfish from Japan! A Ranchu will flourish in a tank with slow-moving clean water, with suitable temperatures (65°. 72°). The recommended aquarium size for a single Ranchu is 20 to 30 gallons.

The pH range must be within 6.5 to 7.5, while the hardness range should be around 5 to 19 dGH. Make sure to keep the levels of ammonia, and nitrite close to zero. Nitrate should be maintained below 40 PPM.

Filtration and Water Quality

There should be a functioning water filtration system for these fish. Given the delicate nature of this fish, You should elect at minimum a quality hang on the back filter for smaller aquariums.

For larger fancy goldfish setups, you should consider an oversized canister filter to manage nitrates with a quality all-in-one biomedia like BioHome. Setting your filtration up like this ensure you have the most stable water quality to keep your Ranchus in excellent health.

Goldfish Tank Environment

For creating a comfortable and natural environment, you should add a sand or fine gravel substrate. Ensure it’s safe and doesn’t pose any choking hazard because your fish will regularly dig around that part as they like foraging for food.

Feel free to decorate your aquarium but refrain from using anything with sharp edges and protruding tips. If you are using artificial plants, consider silk plants. If you are using aquarium rocks, consider rocks without sharp edges or round ones. Driftwood should be avoided unless you are rounding out edges and ensuring there is plenty of open room to swim.

You can add a variety of plants to make the environment appear more natural. Due to their digging habit, live plants may not always be suitable. Some great plants to consider for fancy goldfish would include:

• Java Fern
• Anubias
• Java Moss
• Water Sprite

Make sure to anchor your plants to rocks instead of the substrate. The difficulty with plants is why many choose to go with artificial plants.

The Ranchu has no dorsal fin. That is not decoration. It is a limitation. Swimming is harder, competing for food is harder, and keeping one with faster fish is a mistake.

Tank Mates

You must be careful in choosing suitable tank mates for the Ranchu Goldfish. They are best paired with other fancy goldfish such as:

• Black Moor Goldfish
• Oranda Goldfish
• Pearlscale Goldfish
• Fantail Goldfish
• Ryukin Goldfish

Final Words

Ranchu goldfish stand out easily from other fish aided by their unique body. The wen on their head, combined with their round body, and arched backs make them look special. You will be impressed at how lovely they appear when swimming, thanks to the horizontally spreading double tail.

If you take good care of these fish, your aquarium will be rightly populated with one of the fanciest goldfish you can find on the market. They will stay with you for a long time and keep you entertained! Ranchus keep a goldfish tank lively and entertaining. Consider adding these beautiful creatures!

Black Moor Goldfish have telescope eyes that make them nearly blind in competitive feeding situations. They are slow, clumsy, and get outcompeted by every other goldfish variety.

Never mix black moors with single-tail goldfish. The moors will lose every feeding competition.

Have you just purchased your first Black Moor Goldfish? Congratulations on being a new fish parent and thank you for taking the time to research how to care for them. You will find that not only are they easy to take care of, but their beautiful colors make them a great addition to any home or office.

Of all the fancy goldfish which have attracted the interest of the home aquariums of beginner aquarists, one the most distinct aquarium fish is undoubtedly the black moor goldfish. Named for its beautiful black coloring, this is a peaceful type of goldfish that is very easy and rewarding to care for. What distinguishes the black moor from other fancy goldfish types are, mainly, its “dragon” eyes. As one of the telescope goldfish, these fish have eyes with a comic and endearing bulging appearance.

It’s important to follow the proper care specifications in order to ensure a long and healthy life for your new friends: here’s my comprehensive guide to black moor goldfish care.

A Brief Overview of the Black Moor Goldfish

Origins and Habitat

Like all goldfish carassius auratus, the lineage of the black moor has its beginnings in the Prussian carp, a wild carp specimen found in parts of North America, Europe and most notably, Asia. The first incidence of carp being caught and domesticated, however, occurred in China.

The black moor goldfish is a result of selective fish breeding done in China and Japan to obtain and retain its defining genetic abnormality: telescope eyes. This was done by confining fish with such eyes to a single pond, leading to a larger spawn. The unqiue black coloring and long tail fins of the black moor were thus bred into permanence.

What Does they Look Like?

With bulging eyes and a metallic coat of black scales, the black moor goldfish has an easily recognizable appearance:

Body

Like many other fancy goldfish, the body of the black moor goldfish is rotund, with an egg shape. This is offset by their beautiful tail and anal fins, which are long, graceful and flowing. Meanwhile, their pectoral and dorsal fins tend to be larger.

Color

The black moor goldfish gets its name from the distinct, fully black coloration of its scales. However, this beautiful metallic black color is not seen until they get older. As a juvenile, the scales of a black moor goldfish have a color more accurately described as dark bronze. Beyond maturity, when it begins aging, a black moor’s fins may turn grayish, but don’t begrudge them for not staying true to their name.

Eyes

And now for the best part of the black moor goldfish: its large, bulging eyes, which are quite fittingly called telescope eyes (and alternatively, dragon eyes). As they age, black moor goldfish’s eyes tend to get bigger. So, if you look into a tank full of these fish, you can easily pick out the eldest among them by the size of his or her eyes. The bulging eyes phenomenon is a result of intraocular pressure, which causes the fancy goldfish to, ironically, have very weak eyesight. 

Gender Differences

Telling the sex of a black moor is decidedly difficult, although males do tend to be smaller than females. During mating season, however, the fins of a male black moor goldfish is covered with breeding tubercles, which look like little white bumps.

Temperament and Activity Level

Whether you put your black moors in with other tank mates or in a community tank, you will be pleased by their friendly and peaceful temperament. That said, the best course of action is to put these slow swimmers in with a shoal of other black moors.

Not only that, but their low activity level also makes black moor goldfish care easy: these fancy goldfish like to simply swim back and forth across their tank without bothering any other fish. You’ll often find them swimming leisurely in the middle of the tank, although you shouldn’t be surprised to see your fish concealing him or herself in the decorations or in the substrate.

What are Good Tank Mates?

Choose the members of your aquarium carefully. As these fish are fragile and peaceful goldfish carassius auratus, their chosen companions should have a similar disposition and set of traits. This is a very important aspect of black moor goldfish care as it ensures that your fish won’t be bullied or injured. This is not only limited to fin nipping but extends to their eyes, which are easily injured.

Good Tank Mates

For non-fish the best tankmates would be:

• White Cloud Minnows
• Dojo Loach
• Giant Danios

Many fish available will need different water temperature requirements. Peaceful and schooling fish like minnows your Goldfish may try to eat, but they are are fast enough to get away and not be stressed out in larger tanks. You will need to worry about feeding though as fancy goldfish are slow swimmers and eaters.

Black Moors have terrible eyesight. Tank decorations with sharp edges become hazards. The tank you build for this fish has to account for what it cannot see.

The best tank mates for a black moor goldfish would be other goldfish of the fancy variety, such as:

• Fantail goldfish
• Lionhead goldfish
• Oranda Goldfish
• Pearscale Goldfish
• Ranchu Goldfish

Inverts like freshwater shrimp are going to be a bad idea. While shrimp is fast enough to get away, the stress of being constantly chased could make them jump out of the tank. Snails would be a better choice with nerite and the mystery variety being known to coexist peacefully with your black moors.

Fish Species to Avoid

You should at all costs avoid pairing your black moor with territorial or aggressive goldfish varieties. Such types of fish are known to nip at the long flowing fins of black moors, which can cause fin rot. It can also be quite stressful for black moors to try and avoid aggressive tank mates, which in turn might affect their health and lifespan. Such tankmates that do not pair well with Goldfish would be Cichlids.

What Do Carassius Auratus Eat?

Most goldfish varieties are omnivorous fish, which means they is fed food of the meat as well as plant variety. Although this extends your range of options, you should also be warned that, as fish with big and hungry appetites, your black moors are liable to start feeding on anything you put in your aquarium.

Dry pellets and flakes can easily be fed to a black moor. That said, you should also aim to create variety in their diet to ensure good health. You can feed them vegetables such as broccoli, spinach and lettuce. Make sure to stream your veggies before introducing as this sterilizes them. Specialized frozen foods are highly recommended as they offer the best nutritional value you can get in the hobby. High protein foods help to bring out the black coloration of these fish quicker.

What About Live Foods?

As carnivores, black moors take well to certain easily digestible freeze-dried live foods or frozen live foods, such as blackworms, bloodworms, brine shrimp, tubifex worms, and daphnia (brine shrimp has the lowest nutritional value of all I mentioned). Before feeding freeze-dried foods to your black moors, however, you should soak the food in some aquarium water first to facilitate a smoother digestion process. Soaking with supplements like Vita-Chem will help boost the nutritional content of the food.

How Much and How Often to Feed

Most goldfish carassis auratus varieties should be given food several times a day (though most fish keepers can only do twice a day), and the same is true for the black moor goldfish carassius auratus. But keeping their big appetite in mind, it’s also important not to overfeed your black moors. Their internal organs are squeezed into a compact body, which can lead to fatal digestive problems such as constipation, when the fish is given excessive food.

Moreover, be sure to eliminate any leftover food so as to keep the water unpolluted and safe for your fish to live and thrive in. Using a rule of thumb of only feeding what your fish can eat in 2 minutes is a good guideline to work with.

How to Set Up Your Fish Tank

Remember, goldfish are descended from carps. As such, it’s best to try to ensure a tank environment that closely mimics the natural habitat of a carb. Black moors have weak eyesight and love to feed on almost any small object they find, which is important to keep in mind. Murky, moderately brackish water with a gravel substrate should be a good fit for your black moors.

Furthermore, considering that they are weak swimmers, the optimal tank shape for them is long rather than tall. This gives them more swimming space. If it’s tall, it is harder for black moors to reach any food on the surface.

Minimum Tank Size Considerations

Despite their relatively small size, these fish do take up a lot of space due to their long and large fins. So, for a single black moor goldfish, you should provide at least a 20 gallon aquarium. Then, for every new fish you add, you should add another 10 gallons.

Substrate

Care should be taken when selecting substrates for goldfish. Goldfish will regularly dig in the substrate and with their large mouths, it is easy for them to accidentally shallow gravel. I would recommend a sandy substrate for goldfish as this allows them to forgage freely and split out any sand bits as they dig around the tank.

Decor

Despite their slow swimming speed, black moors are big eaters who are prone to nibbling on almost anything they find. So, it’s best to avoid putting a lot of tank décor in their aquarium. They might just start chewing on it. That said, if you must include decor, ensure that they have smooth surfaces and don’t have any sharp or protruding edges. It’s best to steer clear of driftwood and sharp rocks.

Plants

As they are known diggers, don’t be surprised if your fish start digging up any live plants you’ve planted in their substrate. The best way to work around their digging nature is to attach plants to aquarium rocks. You need to be selective on your plants though, as goldfish will eat many live plants and their temperature requirements are not compatible with most plants.

The safest plants to use on goldfish would be:

• Java Fern
• Anubias
• Java Moss
• Hortwort
• Water Sprite

All the plants above are beginner aquarium plants, so you can still maintain a easy to keep tank! You can also use artifical plants. Silk plants are better to use than plastic ones as they will lack the sharp edges that will harm your fish.

Water Quality (Care)

Here are the specifics of maintaining optimal water quality.

Filtration

It’s recommended to include an efficient filter in your black moor’s tank. This ensures that the water stays clear, which is important since black moors produce a lot of waste. For smaller tanks a quality hang on filter like an aquaclear or seachem tidal would work well.

For larger tanks, it would be best to consider using a well made canister filter. Goldfish are bulky and large. This size makes them hard on your bioload. A canister filter is designed to handle large bioloads. With goldfish tanks, I would recommend loading up on a quality biological media that can process nitrates. I feel Biohome Ultimate Filter Media is the best complete filtration media when it comes to high bio-load non-planted tanks.

Water Parameters

As black moors are an artificially bred species, there is no exact habitat you can replicate for them. However, we do know that their black color appears more quickly in low water temperatures. So don’t set the tank up in any room that get hot, or near any heat source (e.g. A fireplace), as this will affect water temperatures. They also benefit from neutral pH levels. Let’s look at some specifics of water conditions for these freshwater fish:

• Water Temperature: 65.0 to 72.0° F  / 18.3 to 22.2° C
• pH Range: 6.0 – 7.5
• Lighting: Strong lighting is required to help your ocularly impaired fish.
• Hardness Range: 5 – 19 dGH
• Salinity: Below 10%; specific gravity should be below 1.002
• Water Movement: Moderate

Aquarium Maintenance

It’s of utmost importance to ensure clean water conditions for your fish as it directly affects their health. About 20% of the water should be changed on a monthly basis to keep phosphate and nitrate levels at a healthy level. What’s more, it’s recommended to make use of a gravel siphon to remove elements such as organic debris and sludge.

Test Water Conditions

If you’re committed to ensuring a long life for your fish, you should invest in an aquarium test kit. It allows you to determine whether the mentioned water parameters are being maintained properly in your black moor’s tank. 

How to Breed

It’s relatively easy to breed black moors on your own in a tank. To get your black moors to mate and start laying eggs, create the following conditions.

Breeding Tank Setup

Start by moving your pair of breeding black moors to a separate tank (video by All Blue Amante Del Pesce). You should aim to ensure that there are adequate surfaces such as plants and decor for the female to lay eggs when it’s time.

Breeding Temperature

Once your fish are in their tank, start by slowly lowering the temperature to 60° F (15.5° C). Then, gradually increase the water temperature by 3° daily until your fish look ready to mate. You should also make daily water changes of 20%. This will bring on spawning season.

After Breeding

Once your female fish lays her eggs, the male will go on to fertilize them. This process involves a courtship ritual in which the male chases the female around for some time. This might take several hours and you might see as many as 10,000 eggs in the tank by the end of it. Once the eggs appear, swiftly remove the pair back into their original tank as they will otherwise eat the eggs.

Feeding Your Fry

In a week, you’ll have black moor fancy goldfish babies. Congrats, you’ve unlocked a new level in fish keeping! Keep feeding them foods high in protein and iron until they take on an adult size. In about two months, you can start feeding them the same food you give to their parents.

Health and Disease

Concerned about the health of your freshwater fish? Here’s what you need to know if you have a sick fish.

Signs of Health

If your fancy goldfish are swimming about normally, that’s a good indicator of health. They should be regularly eating and should sign good colors and believing should not be labored.

Signs of Ill Health

Here are the three main indicators of poor health in your black moor goldfish that anyone practicing fish keeping should know:

• Their appearance. Note whether there is any dull coloration, color changes, or colorless patches. If you notice any significant color changes, your black moors is suffering from velvet disease or skin disease.
• Their movements. Healthy goldfish swim and bob along the middle of the tank. So if you see that they are sitting at the bottom of the tank or floating on the surface, they is afflicted by swim bladder.
• Their appetite. If you notice that your goldfish is not eating properly, they is suffering from ich, which occurs when there is a parasitic protozoan in the body of the fish. In advanced cases, you might also notice white spots, rapid breathing, and isolation.

Common Health Issues and Treatment

Like all common freshwater fish, black moors are at risk of being inflicted by ich, fin rot, fungus, and flukes. With their long fins, they are particularly likely to catch fin rot. However, this is prevented if you maintain a high quality of water in their tank.

If you suspect a swim bladder (symptoms discussed above), check out my freshwater fish diseases post. There is a great video and explanation on treatment and alternative long-term solutions like fabricated “wheel chairs” that hobbyists have used to save their fish.

As a telescopic goldfish breed with poor eyesight, black moors are prone to eye diseases caused by fungi and bacteria (particularly if their tank is not clean and well-maintained). When handling your black moors, always be very cautious so as not to accidentally injure or damage their eyes.

It’s important to keep ammonia and nitrate levels low in your black moor’s goldfish tank. To ensure this, you should aim to replace about 25% of the water volume on a weekly basis. You need to increase the volume based on your test results. Regularly testing your water with an aquarium test kit will help you adjust your water change routine to manage nitrates.

Where to Buy

Black moor goldfish are quite inexpensive and are commonly found. You can find them in chain pet stores. However, I would recommend you either purchase at a specialty local fish store or if you cannot find a good one in your area, looking into an online fish store.

• The Reality of Keeping Pearlscale Goldfish

Pearlscale goldfish are one of the most distinctive fancy varieties you’ll encounter. Those raised, dome-shaped scales genuinely do look like pearls, and the round, almost spherical body is unlike any other goldfish. I’ve covered dozens of goldfish types on our YouTube channel over the years, and the pearlscale is always one that surprises people who haven’t seen it before. That said, after 25 years in this hobby I want to be upfront: that beautiful round body comes with real care considerations. Pearlscales are prone to swim bladder issues, especially when overfed or kept on a poor diet. They’re also slow swimmers that absolutely cannot share a tank with single-tailed goldfish varieties. This guide covers everything you need to keep pearlscales healthy long-term.

What Most Care Guides Get Wrong About Pearlscale Goldfish The Fancy Variety With Unique Needs

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

The Reality of Keeping Pearlscale Goldfish

Tank size requirements are not negotiable. A single fancy goldfish needs at minimum 20 gallons. A single-tail variety like a comet needs 40 gallons minimum, and realistically belongs in a pond. The one-gallon-per-inch rule does not apply to goldfish.

Filtration needs to be oversized. Goldfish produce more ammonia than tropical fish of the same size. Your filter should be rated for at least double your actual tank volume. A 40-gallon tank with goldfish needs filtration rated for 75 to 100 gallons.

They are cold-water fish that do not need heaters. Goldfish thrive between 65 and 72 degrees. Putting them in a heated tropical tank stresses them and shortens their lifespan. Room temperature water is fine for most homes.

Biggest Mistake New Owners Make

Putting a goldfish in a small bowl or tank without filtration. Goldfish produce massive amounts of waste. Without proper filtration, ammonia levels spike within days and the fish suffers organ damage long before it shows visible symptoms.

Expert Take

The best goldfish keepers I know run heavy filtration and do large weekly water changes. There is no shortcut or trick that replaces those two fundamentals.

Species Overview

Classification

Origins and Habitat

Originating in the early 20th century, the pearlscale goldfish is a relatively new addition to the family of fancy goldfish. Unlike the slender common goldfish, the Chinshurin (as is their Japanese name) have an adorable rounded body, which increases their popularity.

Most species of goldfish are bred in China or Japan. However, modern day pearlscale goldfish are bred and developed mainly in England. But like most fancy goldfish, ping-pong goldfish are bred and kept all over the world. Because there are specially bred goldfish, there are no Pearlscale fish in existence in the wild.

What Does the Pearlscale Goldfish Look Like?

There are many ways to tell goldfish pearlscale apart from others:

Body

One of the first things you’ll notice when you lay your eyes on a pearlscale goldfish is its egg shaped round belly (many also compare it to a golf ball), which is offset especially by its compact and stubby body. In fact, this roundness is what inspires the “ping-pong goldfish” moniker.

Accompanying the short and rounded body are beautiful fins that flow ethereally in the water. They have a single dorsal fin, while the rest of the fins are paired. Of these, the twin tailed fin is the most remarkable, as it has a forked appearance.

The wen fish or crown pearlscale goldfish (named for the crown atop their head) have a slightly different appearance, with large and distinct bubbles on their heads. These is given the name of high-headed or hooded pearlscales.

Scales

What truly sets the pearlscale goldfish apart are its distinct scales, which are nacreous (reflective and translucent tissue). These scales are caused by calcium carbonate deposits due to a genetic mutation. Arranged in visually pleasing rows, these scales have a shiny and luminescent appearance that have a pearl like appearance (and hence the name!), and a bead-like texture.

You won’t see these pretty nacreous scales until your goldfish are older, however. To the untrained eye, young fish of this goldfish species is difficult to tell apart from the common goldfish.

Color

The golfball pearlscale goldfish comes in a wide variety of colors and patterns. Most commonly found are solid colored specimens, which is covered in white, red, blue or black. Calico and chocolate brown varieties are also found of this beautiful freshwater pearlscale fish. There are many types of pearlscale goldfish available. The video below from Molly Babe Aquatics gives a great example of the variety out there.

Temperament and Activity Level

One of the reasons why pearlscales are so popular as pets is their docile and peaceful temperament. Furthermore, they’re slow moving, slow swimmers. Because of this, they are relatively low-maintenance, and they don’t exhibit aggression.

Pearlscale goldfish are quite easy-going compared to other freshwater fish, preferring to spend their days swimming about slowly (unlike, for example, wakin goldfish who are known for fast swimming). However, just because they’re not fast swimmers doesn’t mean they have a low activity level: sometimes, they like to explore and play, so it’s a good idea to put them in a sizeable goldfish only tank.

What are Good Tank Mates?

Thinking of putting some pearlscale goldfish into an existing aquarium? Consider what fish make good tank mates for them, and which ones don’t:

Good Tank Mates

If you have a peaceful community aquarium, great news! Some pearlscale goldfish will make a wonderful addition to it, as they can cohabitate easily with other fancy goldfish and docile freshwater fish. Here are some good tank mates for pearlscale goldfish:

• Black moor goldfish (or other telescope goldfish)
• Fantail Goldfish
• Oranda Goldfish
• Lionhead goldfish
• Ranchu Goldfish

Other than fish, certain snail species also go well with pearlscales, such as mystery and nerite snails.

Fish Species to Avoid

As mentioned before, goldfish pearlscales are slow swimmers. As such, it’s important to keep them away from fast swimming and aggressive fish, because they might end up nipping at the fins of your pearlscales and out competing them for food. Accordingly, here are some fish species you should avoid putting in with your pearlscales:

• Comet goldfish
• Wakin goldfish
• Shubunkin goldfish (pictured above)
• Koi Fish

Furthermore, note that many tropical fish should not share the same aquarium as your pearlscales, as they have different temperature requirements. Even if no fin-nipping occurs with tank mates, feeding time will be difficult for your pearlscale goldfish if the tank mates are fast.

Pearlscales love vegetables, such as cucumbers, frozen peas (as well as deshelled peas), and lettuce. These are great for pearlscales as they keep intestinal problems (such as constipation) at bay. Make sure to steam vegetables before feeding them to fish to sterilize them

Furthermore, limit protein for your pearlscales; it should make up only about 30% of their diet. Excessive protein can cause health complications for pearlscales.

What About Live Foods?

You can include live foods in your pearlscale’s diet every now and again. Brine shrimp, Daphnia, blood worms, blackworms, or Tubifex worms are good live food options for your pearlscale goldfish. Keep in mind the risks of diseases when feeding live food. The safest way to feed live food is to cultivate your own, but this is not for everyone.

How Much and How Often to Feed

A balanced and healthy diet for a pearlscale goldfish will be one made up of a mix of high quality frozen, pellets, and flakes which are given to them at least twice a day. Only feed what your fish can eat in 2 minutes to avoid any excess food in the tank.

Tank Requirements

Fish Tank Size

The recommended minimum size for a pearlscale goldfish aquarium is 20 gallons. Even better if you can make it 30.

This is because, although they’re weak swimmers and slower swimmers than other similar goldfish species, pearlscales do like to swim around their aquarium. More importantly, they need a lot of oxygen and produce a lot of waste. A general rule of thumb is to add 10 gallons of tank capacity for every one fancy goldfish after the first 30 gallons.

Tank Setup

Here are some particulars on setting up a freshwater aquarium for your pearlscale.

Substrate

A sandy substrate is the best option if you want to create a natural environment for your pearlscales. This is to mimic their natural environment as pearlscales enjoy digging through their substrate. If you go with gravel, it’s important to ensure that you’re getting larger and smoother gravel substrate. Otherwise, they might accidentally swallow some. 

Decor

One of the defining characteristics of pearlscales is that they have very delicate and breakable scales. This is why it’s important to avoid putting them in a crowded aquarium. If your existing tank has many decorations and aquarium rocks with sharp edges (or any other sharp objects), it’s best not to put your pearlscales in it as they might accidentally bump into them and have their scales fall off.

If this happens, the fish will not regain its original “pearl” scales; instead, regular scales will grow in their place (although some aquarists say that additional calcium helps here, this is undocumented). That said, aquarium driftwood and plants are okay. You can smooth out driftwood with sandpaper and cut off sharp edges.

Plants

Plants are a great addition to a pearlscale goldfish aquarium, because these fancy goldfish love darting in between and playing with live plants. In fact, a natural pond-like habitat is very good for pearlscales. If you want to put live plants with your pearlscales, go with cold-hardy and beginner plants like Java fern, Hornwort, Anubias and Anacharis. Goldfish in general do not have an appetite for Java Fern and Anubias, but every individual fish is different.

Pearscale Goldfish Care (Water Quality)

Nutrition, clean water, and stress management are the keys to proper Pearlscale goldfish care. Let’s focus on filtration and maintenance.

Filtration

In the case of pearlscales, biological filtration is best as it allows for a high level of water quality, which keeps them safe from common aliments and stress.

With a decent filtration system, both your fish’s waste and leftover food will be dealt with. This is particularly important because pearlscales are slow eaters and will take their time to get to their food. A hang on back filter at minimum are best to use given the high bioload these fish add to an aquarium.

A canister filter should be considered for larger fancy goldfish tanks. Their large mature bulky mature sizes and general foraging habits generate a lot of waste particles in the water that need to be filtered out. A large filter like a canister will ensure mechanical filtration is top tier and nutrients is processed appropriately.

In fish only fancy goldfish tank, a complete media like biohome is an ideal solution for keeping nitrates down when pairing with a canister. Biohome is amazing for high load fish only tanks – such as a large fancy goldfish tank.

Water Parameters

As the species of pearlscale goldfish isn’t naturally occurring, there is no natural habitat you can emulate for them in your tank. However, their preferences are well known. They can withstand a wide temperature range, and do well in cold water and neutral pH levels. Watch out for frequently fluctuating pH levels as this can cause disease and ill health. Nitrates is also a common issue with fancy goldfish tanks. Regularly testing your water will assist in determine the water change volume and frequency.

Here are some specifics:

• Water Temperature: 65.0 to 75.0° F
• pH Range: 6.0-7.5
• Hardness Range: 4 – 20 KH
• Salinity: Below 10% (with a specific gravity below 1.002)
• Water Movement: Moderate
• Nitrates: Keep below 40

Aquarium Maintenance

The tank you place your pearlscale goldfish in should be well-maintained if you want them to stay healthy. Scheduled weekly water changes of 1/4 to 1/3 are required as pearlscales produce a lot of waste. As mentioned earlier, you can also choose to include snails in the tank as they make short work of algae and help to keep the tank clean. Since goldfish tanks require a lot of regular cleaning, an investment in a tool like a python cleaner can help save you time.

How to Set Up Your Fish Tank

Beyond providing a good filtration system for your pearlscale goldfish’s tank, consider the following set-up requirements:

Tank Size

As you already know, at least 30 gallons is required for housing a pearlscale goldfish, with an additional 10 added for each new goldfish you introduce into the tank. This large amount of water is required so that the waste is diluted, and it lets you keep water changes scheduled to once a week.

Tank Shape

A large surface area is optimal for keeping fancy goldfish as it prevents an oxygen shortage. Remember, the tank shape determines the surface area; as such, it’s best to go with an elongated tank as opposed to a tall one. If you want a round or oval tank for your goldfish, it should be narrow at the top and wide in the middle for maximum surface area.

How to Breed

In the right conditions, pearlscale goldfish can spawn easily and readily. They are egg layers who can breed in small groups as well as large ones.

Breeding Conditions

Start by providing a breeding tank that is at least 20 gallons. A few weeks before breeding, make it a point to separate the males and females as this will increase their interest to spawn. When you’re ready, release the males and females in at the same time. Avoid rough handling.

Drop the temperature slowly to around 60°F, then gradually warm it at 3°F until spawning occurs., when the temperature is between 68° and 74°F, spawning will begin. This is a good time to feed your pearlscales live food such as worms and brine shrimp. Try to feed at least thrice a day. As for water changes, you should aim to make partial changes of about 20% per day.

How to Tell if Your Pearlscales Will Start Breeding

As the tank temperature increases, the male pearlscale will chase the female around (not aggressively) for several days. Both males and females will have a vivid, more intense color.

If you see a gyrating action in your freshwater fish, that means they’re spawning. The female will be pushed against any plants inside the aquarium during the process, which will cause tiny eggs to drop out, which can then be fertilized.

The spawning process can last up to 3 hours and produce about 10,000 eggs. Once this is done, remove the goldfish from the breeding tank, because they will start trying to eat the eggs. In 4 to 7 days thereafter, you should have a brand new group of juvenile pearlscale goldfish.

Health and Disease

Signs of Health

If your pearlscales have shiny scales and eyes, are swimming about their tank most of the day, and feed periodically throughout the day, you can safely assume that they’re healthy and happy. They should also retain their round body shape.

Signs of Ill Health

If your fancy goldfish seem lethargic, aren’t eating much, have pale skin, are hollow-bellied, or have fraying fins or scale loss, that means their health or life expectancy is compromised. Here’s what is ailing them:

Common Health Issues and Treatment

Pearlscale goldfish are prone to being afflicted by all common freshwater fish diseases, such as fin rot, ich, flukes and fungus.

Because pearlscale goldfish have long and flowy fins, they are particularly prone to fin rot, which mainly occurs in poor quality water. So to prevent this, you should aim to provide high quality water for your goldfish.

Swim bladder disease is another commonly occurring disease in pearlscale goldfish. This is due to the compactness of their intestinal tract, which is easily affected by taking in too much food or even air. I go over swim bladder, dropsy and other serious goldfish aliments in my freshwater fish diseases post.

Where to Buy

As a common fancy goldfish, pearlscales are readily available in most pet shops, both online and off. However, the finest pearlscales are imported from countries like China. It is best to work with a what you see is what you get (WYSIWYG) online fish store to get select varieties.

Is the Pearlscale Goldfish The Fancy Variety With Unique Needs Right for You?

Before you add a pearlscale goldfish the fancy variety with unique needs 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. Pearlscale Goldfish The Fancy Variety With Unique Needss 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 pearlscale goldfish the fancy variety with unique needs 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 Pearlscale Goldfish The Fancy Variety With Unique Needs Compares to Similar Species

Want a pond fish? Get comets or shubunkins. Want an indoor aquarium goldfish? Get fancies and plan for a 40-gallon minimum. Want a low-maintenance pet? Get a betta instead.

Choosing between similar species is tricky. Here’s how the pearlscale goldfish the fancy variety with unique needs stacks up against some common alternatives.

The pearlscale goldfish the fancy variety with unique needs 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 pearlscale goldfish the fancy variety with unique needs 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 pearlscale goldfish the fancy variety with unique needs needs, it’s hard to beat. If not, there are alternatives worth exploring.

The cherry barb is the anti-tiger barb. It is peaceful to a fault, will not nip fins, will not chase tank mates, and will not defend itself when something bigger pushes it around. That makes it one of the best community fish in the hobby, but it also means you have to protect it. Put cherry barbs with anything aggressive and they will hide, fade, and stop eating.

In the right tank, with dark substrate, live plants, and a group of at least six, male cherry barbs develop a deep crimson color that rivals anything in the tropical fish world. Skip those conditions and you get a washed-out pink fish that never shows you what it is capable of. This guide covers what it takes to bring out their best, because the cherry barb does not demand attention. It earns it quietly, and only when the conditions are right.

The cherry barb is proof that a barb does not have to be a bully. But being peaceful has consequences. Your job is to make sure those consequences never catch up to it.

What Most Care Guides Get Wrong About Cherry Barb The Peaceful Barb That Works in Community Tanks

The most common mistake I see with cherry barb the peaceful barb that works in community tankss 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. Cherry Barb The Peaceful Barb That Works in Community Tankss 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, cherry barb the peaceful barb that works in community tankss are adaptable.

A Brief Overview Of The Cherry Barb

The Cherry Barb is scientifically called Puntius titteya , they are one of the friendlier barbs you can purchase in the aquarium hobby and are ideal for a community tank. They are also great barb fish for planted tanks as the male’s reds contrast well with many green plants.

Classification

Origins and Habitat

The Cherry Barb originates from Sri Lanka from the Cyprinidae family. The fish live in freshwater ponds and slow-moving water sources across Sri Lanka. These freshwater fish have also been found in Columbia and Mexico, where they have adapted well to their surroundings.

The fish thrive in tropical rainforest conditions where the temperature rarely changes.

Even though the Cherry Barb Puntius titteya is thriving in the aquarium scene, the fish is now vulnerable in its natural environment. This is due to its popularity with aquarium owners and the disappearing waters in their shrinking natural habitat. Fortunately, these fish are now tank bred and easy to find in fish stores.

What Do Cherry Barbs Look Like?

Cherry Barbs are long, thin, brightly colored fish. As the name suggests, they are bright red, with the male species generally being more vibrant than the females, which are more of a tan color. The females also look fatter than the males.

All Cherry Barbs have a dark line that runs along the whole of their body. This is a solid brown line, but due to their scales, it can look dotted.

Their fins are quite small and can look translucent. The dorsal fin is shaped like a half shell and is halfway down its back. When they swim, this fin lies flattened so that they look like little torpedoes gliding through the water.

Temperament and Activity Level

These fish are peaceful and like nothing better than swimming around all day in their group. You should buy Cherry Barb fish together due to their schooling nature; they like to swim around in groups. This gives them the feeling of safety and security when swimming together.

They are active fish and enjoy swimming quite fast. They are also curious fish who like searching things out. They may spot something that they want to explore and leave the group for a second but will always return.

The only time that you will see any signs of aggression from the Cherry Barbs will be while mating. Males will then dominate the female and other males.

What Are Good Tank Mates?

Due to their peaceful nature and social temperament, Cherry Barb tank mates can be many other fish species. They prefer to school in a group of other Cherry Barb fish, so keep this in mind when getting other fish.

Good Tank Mates

The best Cherry Barb tank mates for these fish would be other peaceful smaller fish species that share the same nature as your Cherry Barbs. They also enjoy sharing the tank with larger bottom dwellers. 

Some of the best fish species for tank mates would be:

• Tetras
• Rasboras
• Gouramis
• Small catfish like Otocinclus catfish

They are also suited to shrimp and other invertebrates, such as Ghost Shrimp, Cherry Shrimp, or Mystery Snails

Fish Species to Avoid

Cherry Barbs is shy around other fish species, so it’s better to avoid larger or more aggressive fish species. Any fish that can fit the barb in its mouth should be avoided. Other more aggressive barbs like the Cherry Barb should be avoided.

Tank Requirements

You should make sure that you have the right sized tank and environment for your Cherry Barb fish. They are easy to look after as long as they have the right conditions and habitat.

Tank Size

As Cherry Barbs are schooling fish, you should allow for around six fish initially. The minimum tank size should be between 25. 30 gallons.

Tank Setup

The natural habitat for these fish is shallow water with lots of live plants, so you should try to re-create this where possible. They are naturally a timid fish, and will not be as social without the comfort of plants. You should try to have some plants on the surface of the tank to help them to feel at home. Some of the best plants to choose from are water wisteria, hornwort, and anacharis.

Dark sand or fine gravel is an excellent substrate for your Cherry Barb. This offers a similar environment to their natural habitat of a dark, silty base. This, along with a well-planted tank, will give them the right environment. In an aquascaped environment, active aquarium soil is a consideration for rooted and carpeting plants.

The dark substrate will also add to the aesthetics of your fish tank with the black substrate against the bright red of the fish. It’s a color explosion!

Water Quality

These freshwater fish are a pretty hardy fish and can tolerate a range of water changes and conditions. However, you should ensure that the water quality is suitable for the fish to avoid any illness.

Filtration

A standard hang-on back filter should be suitable for your Cherry Barb care, which will keep the water clean at all times. The filter should have a gentle flow as the fish are used to slow-moving water and will not do well in fast currents. For a planted tank, a canister filter is a good consideration to provide added mechanical filtration and flow.

Water Parameters

The ideal water parameters for your Cherry Barb freshwater fish would be:

• Water temperature: 73°F. 81°F
• pH level: 7.2. 7.5
• Water hardness: 5 dH. 19 dH

Aquarium Maintenance

To give your Cherry Barbs a healthy fish life, you must ensure that your aquarium is maintained to a high standard. The water should be kept clean, and parameters met at all times to give the best Cherry Barb care. The tank should also be cleaned regularly.

Test Water Conditions

Your tank water should be tested regularly to make sure that the parameters are met. By investing in high-quality water test kits, this will give you the accurate result that you need for your Cherry Barb fish.

The water should be tested for the following elements:

• pH: This is the power of hydrogen level that tells you how acidic or alkaline the water is. 
• Ammonia: This is a byproduct of your fish’s waste and is toxic for your fish.
• Nitrite: Ammonia is broken down to make nitrite which is also toxic.
• Nitrate: You should not have more than 40ppm of nitrate in your water.

How to Set Up Your Fish Tank

Once you have bought everything you need, you will need to set up your Cherry Barb tank.

How To Set Up a Fish Tank

The first thing to do when setting up your fish tank is to make sure that everything is clean. You shouldn’t use any soap or disinfectant to clean as this may harm your fish; rinsing under water is sufficient.

The substrate should then be added to the tank, a couple of inches is plenty. Once you have done this, place an upturned bowl on the substrate. This will make the process of adding water easier.  The filter and heater should then be added but not switched on just yet.

Dechlorinated tap water can then be added to the tank. Do this by pouring it over the upturned bowl so that the substrate isn’t displaced all over the tank. To make the water fish-friendly, you need to start the nitrogen cycle. A little liquid ammonia should be added to the water to start the cycle.

Your decorations and live plants can then be added, making sure that these have been rinsed through. Live plants can be planted in pots or directly into the substrate, and all damaged leaves should be removed.

The filter system and heater should then be switched on and kept on all day and all night. Your live plants need light to survive, so your lighting should be switched on also.

The tank is then ready, but you shouldn’t add your fish just yet. The tank should be left to establish itself without fish for at least 10 days. The water parameters should then be tested to make sure that they are appropriate. All water parameters should be correct before adding any fish, or they won’t survive in the tank.

Once you have reached the correct parameters in your fish tank, you can then add your fish. 

Health and Disease

The Cherry Barb is quite a hardy fish species; however, they can still be susceptible to ill health.

Signs of Health

Prevention is far better than curing illness, and you should make sure that your fish are looked after. This will help to avoid many illnesses that can affect the fish. 

A healthy Cherry Barb is colorful and should be actively swimming around the tank with its group.

Signs of Ill Health

The first sign of ill health in a Cherry Barb would be changes in the behavior of your fish. If you notice anything different, check your fish out. Some of the changes in behavior is: lethargy, not eating, or rubbing their body on the tank. They could also be suffering from ripped fins, which is a sign that there is something wrong.

Common Health Issues and Treatment

The most common disease in your fish would be Ich. This is also known as white spot disease, and the water should be treated with an Ich medication to get rid of this. 

They can also suffer from other conditions, such as velvet disease, fin rot, and dropsy. These conditions are all curable as long as they are correctly treated in time. Your fish need to be quarantined while being treated. Check out my freshwater fish disease article for identification and treatment of the most common diseases in our hobby.

Breeding

Cherry Barbs are easy fish to breed and will spawn often. The breeding process is simple compared to other fish species. The time-consuming work is in the preparation. You will need to set up a breeding tank with a similar habitat to their permanent tank.

You will need two tanks or will need to separate a tank into two areas, one for the breeding pair and one for the eggs. Cherry Barbs will eat the eggs once spawned if they are not separated. The breeding tank will need to be well planted as they like to hide and protect their eggs in the plants. 

Once ready to spawn, the males will become more aggressive and start to chase the female. He will also become brighter in color, as will she. The female can lay between 200 and 300 eggs, and these will be scattered over the plants and substrate. You need to quickly remove these once spawned and put them in a separate tank.

Be careful not to add your female fish back into the permanent tank as soon as she has spawned her eggs. She will be tired and needs to regain her strength before being put back in with the male fish.

The fry will hatch over the next few days and should be fed on foods such as vinegar eels or micro worms. After a further couple of days, they will begin to swim around. As they get bigger, they can start to be fed on larger live foods like brine shrimp.

The fry will reach adulthood at around two months old, and at this point, they can be added to the permanent tank with other fish.

Are Your Cherry Barbs Male or Female?

There are a few ways that you can tell if your Cherry Barbs are male or female. The first one would be their color. The males are a brighter cherry red color, where the females are paler in color and can be tan or almost white.

The lateral line that is found along the whole of their body from the head to the tail is different. This is a darker brown color in the female Cherry Barb than the male. The last difference would be the shape of the fish. The female Cherry Barb is slightly rounder in shape in the stomach area than the male; the male fish is slimmer.

Availability

You can buy both male Cherry Barbs and female Cherry Barbs from most pet stores as well as online fish stores. Make sure that you purchase your fish from a reputable supplier and that they are healthy fish. You don’t want to buy fish that aren’t looked after and could spread diseases to your other fish.

What You Need to Buy

You need to start with the right tank with lighting and a filter system. They are a tropical fish, so you should invest in a heater for the tank. You should then get the substrate, plants, decorations, quality fish food, and maintenance equipment. 

To clean the tank correctly, you should invest in an algae magnet and an aquarium vacuum. You also need to make sure that you have plenty of water testing kits to ensure that your water is at optimal parameters.

Don’t forget your fish!

If I couldIn my experience, Amano shrimp do best in heavily planted or aquascaped setups — not just any planted tank, but tanks where there’s a dense carpet of plant life and healthy substrate. The more plant surface area available, the more biofilm and algae the Amanos can graze on between feedings. I follow Tom Barr’s approach to planted tanks (balanced macro dosing, good CO2) and in those environments Amanos are genuinely thriving — fat, active, and constantly working.

One thing most care guides don’t mention clearly: Amano shrimp are nearly impossible to breed in a home aquarium. The larvae require brackish water to survive — they’ll hatch in freshwater but won’t develop. You need a separate brackish grow-out tank, precise salinity management, and live phytoplankton for the zoea stage. It’s doable but it’s a serious project. For most hobbyists, you’re buying replacements rather than breeding them.

only keep one algae-eating invert in a planted tank, it would be Amano shrimp – no contest. They work harder and eat more algae than any other shrimp species I’ve kept, and at 2 inches they’re large enough that most community fish leave them alone. The Amano shrimp also has a fascinating legacy: Takashi Amano, the man who essentially invented modern planted tank aquascaping, popularized them specifically for algae control. I use them in my own tanks regularly, and this guide covers everything you need to know to keep them successfully.

A Brief Overview Of The Amano Shrimp

Botanically called Caridina multidentata, Amano shrimp are freshwater crustaceans that are native to Japan and Taiwan. The Amano shrimp is known by a variety of names, including Caridina Japonica (previously named until 2006). It’s also called the “Japonica shrimp” or “Algae eating shrimp.”

They are considered the Godfather of all freshwater shrimp species and the seed for the shrimp tank boom in the 90s.

Origins And Habitat

True Amano shrimp hail from the swamps of Japan. Takashi Amano, the founder of modern planted tank aquascaping, helped spread the word about the benefits of keeping these shrimp in a planted tank. The shrimp was named after Takashi Amano for his contributions to the aquascaping hobby. He really is a historical figure in our hobby, and is worth learning more about.

Amano shrimp (AKA Yamato Shrimp) are a unique shrimp in our hobby as they have an amphidromous life cycle. This means that they migrate from salt water to freshwater during their life.

Appearance (What Do They Look Like?)

Amano shrimp (Source) have clear bodies with tan or brown stripes running down the back from head to tail. They have a white stripe that runs from the head to tail and black eyes. Females can be told apart from males by their more elongated lower row of dots. They are one of the less colorful shrimp species. The Cherry shrimp really takes the looks, while the Amano is the workhorse of the aquarium.

Temperament And Activity Level

Amano shrimps are very bold creatures. They do not hide and will be out and about throughout the day. The only time they are reclusive is when they molt, which makes sense because this is when they are the most vulnerable.

What Are Good Tank Mates?

Because of their great utility, you will rarely see Amanos in shrimp only tanks. They are one of the most popular additions to planted and community tanks.

Knowing this, let’s talk about what fish work best with them!

Good Tank Mates (Fish Species)

The following fish get along with Amanos with no issues. Bettas are the only ones with an asterisk, as you will want a larger tank to give the shrimp space to hide if you end up with an aggressive Betta. You want to seek out peaceful fish when selecting tank mates.

• Betta Fish – in a tank, with a cover, that is over 5 gallons
• Guppies
• Small Tetras – like Neon Tetras
• Peaceful Barbs – like the Cherry Barb
• Small Fish like Zebra Danios

Fish Species To Avoid

You should avoid these fish as they enjoy turning your Amano into a tasty snack!

Amano Shrimp eat more algae than any other freshwater invert. If your tank has an algae problem and you do not have Amanos, you are doing it wrong.

• Cichlids
• Goldfish
• Any fish with a mouth large enough to fit the shrimp in its mouth

The Best Tank Mate

If you are looking for the best tank mates, look no further! Amano shrimp enjoy living with their own species. This is because they will socialize and mate with each other without issue. They are also highly compatible with other shrimp, such as the Cherry shrimp.

What Do They Eat?

They are known for eating black beard algae. They specialize in cleaning plants and rocks and will consume leftover fish food. You can also feed them shrimp food, which I’ll go over below.

What To Feed Them

They are very aggressive eaters. If you feed them too well, they will slack on their cleaning duties and stop eating aquarium algae. If you have slower peaceful fish, you will need to scatter food during feeding time to make sure your slower and less aggressive fish get food. They are always active in the tank spending most of their time foraging for food.

There is specialty shrimp food which is suited for freshwater shrimp tanks. It works in mixed tanks as well. Dennerle Shrimp King Food works really well if you want to target feed your Amano shrimp. It’s small enough where the shrimp can grab a pellet and hide away to eat it undisturbed.

Generally, in a mixed tank, you shouldn’t need to worry about food since they are aggressive feeders.

How To Set Up A Suitable Tank

First, it is important to know that Amano shrimps are excellent escape artists. You must have a cover on your tank. They are small inverts, and are great jumpers when they are excited. A covered lid is best, something you see with most rimmed tanks.

For rimless tanks, you will need to get a glass tank cover. Mesh nets are too wide to work for shrimp.

What Is A Proper Tank Size?

For a quick answer, the proper Amano shrimp tank size is 5 gallons. Most aquarists will not keep only Amanos though, so let’s dive in deeper with a rule of thumb below.

Tank Setup

The general rule of thumb for Amano is 1 shrimp per every 2 gallons with a 5 gallon minimum tank size. While this is the rule of thumb, you can often get away with less, as they are extremely active with scavenging and eating waste and consume algae from your tank.

Decor

When decorating, you should choose natural items like driftwood and plants. Amano shrimps will adapt to any setting, but look better in a natural environment because of their color. They tend to stand out under the dark backdrop of driftwood.

Driftwood

Aquarium driftwood is a great choice if you are looking for some plants material for your Amano shrimp. Cholla wood is an excellent plant option, because it naturally decays and provides shrimp with food while also providing them with the perfect habitat.

Mosses

Moss is a crucial accessory in the shrimp tank because it acts as a hiding place. It calms them and keeps them safe, which also seems to make female Amano shrimp brighter than usual. The best moss for Amano shrimps would be Christmas Moss because it’s easy to care for and they love it!

Live Aquarium Plants

Shrimp thrive in tanks with plants. These shrimp are hardworking because they clean algae from all of the plants, and also don’t need any decoration other than a place to hide for safety.

To make shrimp happier, provide rocks and live plants in their habitats to serve as protection. Shrimp love eating biofilms and algae from surfaces, so including plants is doubly beneficial for them.

Plants also absorb excess nitrates in the water to maintain a cleaner and healthier fish tank. Low light plants are best for Amano shrimp setups, so make sure you buy them! Here are a few examples:

• Java Moss
• Java Fern
• Anubias
• Christmas Moss

Substrates

When it comes to filling the substrate in a tank, including small pebbles as a substitute for natural rocks can be beneficial. If other animals inhabit your fish tank, cater to their needs first because Amano shrimps are less demanding to manage. They adapt readily with most changes regardless of how harsh they may seem.

Starting with substrate and pebbles, rinse them thoroughly before placing in the tank. There are substrates that work well for shrimp tanks like Fluval Stratum. Definitely take a look if you’re looking to start out.

Water Quality And Tank Conditions

Water quality starts with quality filtration then maintaining parameters. Let’s focus first on key parameters.

Which Filters Are Most Suitable?

Amano shrimp require water that is dechlorinated and buffered with a neutral or near-alkaline pH. Regularly monitor your tank for anomalies or irregularities, and change 25%-30% of the water every other week. Monitor your levels with a proper aquarium test kit.

TDS is another factor to keep in mind when caring for Amano shrimp. They require the same TDS as Cherry shrimp, which is around 150-200.

As expected, these tiny invertebrates don’t need a large tank for comfort. Ideally, 5-gallon tanks are enough to meet their needs.

When choosing a tank size, in most cases you should go for the bigger size. For example, if you were going to pair them with other inhabitants, like fish or other shrimp, it is best to have a larger tank than settling for one of the smaller sizes. In general, the golden rule of thumb is to opt for the bigger tank over small.

Which Filters Are Most Suitable?

There are many factors that can affect a shrimp tank, but one of the most controversial parts is filters. Some filters might be too powerful and can suck up the shrimp, so it’s important to choose carefully. A sponge filter should provide for adequate water filtration while still keeping your pets safe and happy!

Tank Filtration Process

Always try to create a clean and well managed tank for these pets. As explained before, Amano shrimps are sensitive to nitrates or ammonia levels in the water. Therefore, filtration systems which use large amounts of bio media is advised so that your pet can thrive in the environment you have created for them.

If you are a shrimp purist, one option is to use a cheaper filter for your new shrimp. Sponge filters naturally only offer biological filtration; this means they will not suck up the Amano shrimp. The best place for these shrimp to consume leftover fish food particles is on the sponge’s exterior surface.

On the other hand, if you want to keep more than Amano shrimp, you’ll need a Hang-on the back filter or canister filter. You should put a sponge on the intake as a pre-filter to avoid sucking up any of your Amano shrimp by accident.

Water Conditions – Parameters

Although Amano shrimps are hardy and can tolerate living in a variety of water conditions, they thrive best in freshwater tanks with the following parameters:

Water Temperature

Amano shrimp prefer to live in water that ranges from 65°F – 78°F.

Water Hardness And pH Range

pH should be between 6.5 – 8.0. Water hardness can range from 6-8 DKH

Amano Shrimp Lighting

Amano shrimp do not require any light to live. If you have a freshwater tank with plants, or if your goal is for the Amano’s coloration to come out more distinctly, these animals can also live in an aquarium fitted with a planted tank LED system.

Ammonia, Nitrites, And Nitrates

You should keep the concentration of ammonia and Nitrites at 0, and Nitrates below 20ppm at all times. In cases where these levels are higher than 20 ppm levels, your Amano shrimp may experience major problems.

Copper – The Silent Killer

Amano shrimps are sensitive to copper. Be careful using medications containing this metal in your tank as they can harm the Amano shrimp, such as seachem cupramine or marvel copper safe medications.

There are also aquarium plant fertilizers that might contain copper! Look for fertilizers that are specially made for shrimp to avoid any issues.

How To Breed

Breeding Amano shrimp is a challenge. Unlike Cherry shrimp and other shrimp caridina, they are difficult to breed and many of the shrimp you will purchase from stores and online will be imported.

The biggest challenge with breeding them is when the Amano shrimps are first born, they require saltwater. As the larvae mature, you will need to lower the salinity and get them adjusted to freshwater. This is generally going to be way too involved for many aquarists. Below is a video of what a pregnant female Amano looks like:

Sexing Amano Shrimp

It’s actually quite easy to ID males and females because shrimp anatomy is generally the same for all freshwater shrimp species. Here are some key pointers to help you identify each:

Females

• Brown stripe and dots
• Thick vertical body
• Saddle for the eggs
• Whiter and more pronounced stripe that runs from the top of the female
• Larger than male

Females will attempt to breed after molting.

Males

• Smaller
• Less colorful
• Brown dots versus stripes across the body
• No saddle
• Stripe at the top is more faint than the male

Breeding Process

Breeding is a complex process for Amano shrimp. Describing the process is a whole separate post in itself. Since this post is fairly long already, I’m going to supply a video from Avatar Aquatics that goes over the process and I’ll include a few notes for you below.

• Incubation tank needs to be at saltwater tank salinity (35PPT or 1.026 salinity)
• Use diatoms or pyato plankton to feed your shrimp
• Cover so water does not evaporate
• Move larvae as soon as born and acclimate to saltwater immediately

The female reproductive cycle is as follows:

• Molt to berried – 1 day
• Berried to drop – 17 days
• Drop to next batch – 5-7 days
• Shrimp hatch time: up to 5 weeks
• Total time: 25-30 days

To provide clarification, a female with eggs is called a berried female. You want to remove the female around a week after they become buried. If they are dropping eggs in your display tank, that is also a sign that you can remove her.

If you want scientific backed studies on the process of breeding Amanos, here is the link to the document from the Zoologicial Society of Japan.

One nice side-benefit with Amano is that they are purists. They will not crossbreed with other types of shrimp species. This means if you want to keep a stable population in your tank, Amanos are an excellent choice because they will not breed like crazy like other shrimp.

Hatching Process

The hatching process is one of the most difficult transitions when raising Amanos. You will need to transition them to saltwater within minutes of the shrimp hatching. The video from Avatar Aquatics illustrates how to do it correctly.

The preferred food to use is phyto plankton. It is readily available online and easy to use. I prefer Algae Barn’s phyto.

How To Raise Shrimplets

Congrats, you have baby larvae and are now trying to figure out how to raise them. The next phase is all about maintenance. You will want to feed your larvae every day, and consider doing a water change every other day.

Larvae hit the juvenile stage around 20 days. This is when you will want to consider acclimating them to freshwater. This is another critical and complex step. You will want to drip acclimate the shrimp to freshwater over a 12-24 hour period. The goal is to go from 35PPT to 5PPT within that time frame.

The saltwater side of the hobby sell a number of drip acclimators that you can use. I would recommend using Innovative Marine’s Accudrip Acclimator.

DO NOT put the juveniles in a tank with fish in it. You should use a separate growing tank. Do not move them to a tank with fish until they are at least 1 inch. The grow out tank should be 2.5 – 5 gallons and should require water changes every 2-4 days due to the increasing amount of molting and death of the baby shrimp.

There are lots of reasons why baby shrimp do not make it. They can die during the molting process from a bacterial attack or some may not get enough food. This is part of the process. In nature, many larvae do not survive predators and bacteria.

Let’s cover molting next, as I just mentioned it.

Molting

If you see a whitish shrimp laying on its side that looks half broken, it is likely the result of a molt versus a dead shrimp. If you see a shrimp laying on its side, and it is gray or an orange or pink color, then that is likely a dead shrimp.

So What Is Molting?

The shell of Amano shrimps do not grow along with it. The remains left behind, when the old shell falls off, are called an ingrowth shell, and it needs to be replaced after a few weeks.

What’s Involved In The Molting Process?

The new shell grows slowly under the old one, which is soft. The shrimp then grips tightly to any surface it can find, such as the substrate or plants. It pulls against a half portion of the shell before pulling away from it gradually.

Once the shrimp finishes, it removes the empty shell by quickly curling its tail.

Once The Molting Is Completed

The shrimp’s new shell is typically soft for the first few days before it hardens.  During this time the shrimp is susceptible to attacks, so it usually hides in plants until the shell firms up. 

Molting Related Problems

Yes, molting-related problems exist. For example, if a shrimp fails to molt it will die. Alternatively, the shrimp might only crack off the first part of its shell and then struggle to break open the other half – only to be stressed to death in doing so; it could also happen that the wheel might not break off completely resulting

Causes Of Molting Problems

There are many theories about what causes the various molting problems. Some people think it is related to water parameters, while others believe that changes in diet or inconsistencies in temperature can lead to troubling molting issues.

If your water’s general hardness levels are too low, the shrimp will have a difficult time developing shells. It might not shed its shell altogether, but it will become so soft that you can bend it and not split it. If you want to help your shrimp thrive (and protect their shells), try using GH test kits to make sure your GH stays in the right range.

You should also consider material dosing if your tap water source is soft, or if you use a water softener in your home.

Where To Buy

You can purchase Amano shrimp at a local or online fish store. For online, I would highly recommend purchasing from BucePlant. They are one of the best places online to purchase healthy and vibrant freshwater shrimp.

ASD Suitability Rating: Amano Shrimp

Overall Keeper Difficulty: 5/10 (Intermediate)
Amano shrimp are easy to keep alive but have specific requirements that catch beginners off guard. Here’s how I rate them across the dimensions that actually matter:

Algae Control Effectiveness: 10/10 — Best in the hobby. Nothing touches them for biofilm and hair algae.
Planted Tank Suitability: 10/10 — Thrive in CO2-injected, heavily planted setups. Essential in a serious aquascape.
Beginner-Friendly: 6/10 — Hardy once established, but copper sensitivity and molting vulnerability catch new keepers out.
Compatibility: 8/10 — Safe with most community fish; avoid anything large enough to eat a 2-inch shrimp.
Breeding Difficulty: 10/10 (extremely hard) — Larvae require brackish water. Not a realistic home breeding project for most hobbyists.
ASD Overall: 8.8/10 — If you keep planted tanks, Amano shrimp are non-negotiable. Buy 5-10 at a time for meaningful algae control.

Summary

I hope this article has helped you learn about the Amano shrimp and what to expect when taking care of them.
