Clown loach fish are some of the most popular freshwater aquarium fish. They are clownfish that can be found in Asia, Africa, and Australia. These clownfish live in freshwater environments with a pH level between 6 – 8.5 and dH levels between 5 – 20 degrees on their own, but they will also survive in more acidic water if there is higher gravel bedding to buffer the acidity near them.

The loach fish is a popular pet among freshwater aquarists and also clownfish for marine tanks. They are fun to watch because they clown around the tank, scavenging for food and chasing other fish. Clown loaches can be found in many colors such as red, orange, green, yellow, and blue. They can grow up to 12 inches in length, but usually, only reach about six inches long in the home aquarium.

They are schooling fish and should be kept in groups of at least three. They will do well with other peaceful community fish. They need a lot of swimming room, so an aquarium that is at least 30 gallons is recommended.

Clown loach size

Clown loaches can grow to be as large as 12 inches long.

Clown loach tank size

Clown loaches do well in tanks that provide plenty of cover and hiding spaces. A tank size of at least 20 gallons is recommended.

Life cycle

Clown loaches are egg layers. Once the eggs hatch, they will stay close to their parents until they reach a certain age and size. Clowns become sexually mature after about five years of life at which point spawning can occur any time during the year if conditions are favorable.

Males dig small pits in soft substrates in which the female deposits her eggs. The male then fertilizes the eggs and guards them until they hatch, typically within three days. After hatching, the fry remains near their parents for a period of time to learn how to hunt and fend for themselves before dispersing.

Are clown loach aggressive or peaceful?

They are generally peaceful but they can become aggressive if their environment is overcrowded. Clowns should be kept in schools of at least six individuals to prevent this from occurring and an even larger school would be ideal because the fish enjoy each other’s company and will do best with companionship whenever possible.

Clown loach fish care is not difficult, but there are a few things you need to know in order to keep them healthy and happy.

Clown loaches require a tank that is at least 30 gallons with plenty of hiding places. They like to hide under rocks or plants, so make sure your tank has plenty of decorations.

They also need a good filter and regular water changes to keep the water clean.

Clown loaches are schooling fish, so you should have at least three of them in order to keep them happy. They will eat both live and frozen food, but make sure they have plenty of plant matter in their diet as well.

Clown loach food

Clown loaches are omnivorous and will eat both live and frozen food. They need a diet that is high in plant matter, so make sure to include plenty of vegetables in their diet.

They will also eat meaty foods, so you can give them some live or frozen brine shrimp, bloodworms, or daphnia.

Clown loach water parameters

Clown loach fish like their water to be a pH of around neutral, with a hardness that is not too high. They can tolerate temperatures up to about 86 degrees Fahrenheit (30 degrees Celsius). The ideal range for keeping clown loaches is between 72 and 78 degrees Fahrenheit (22 and 26 degrees Celsius).

They also prefer a low level of nitrates and phosphates, with zero ammonia or nitrite. They will not survive in water that has high levels of either one of these chemicals.

Clown loach breeding

Clown loach fish are very easy to breed. They will readily spawn in most community tanks that have a pH of around neutral, and the hardness should not be too high. Clown loaches can hold sperm for up to four months after mating, so it is possible they may produce two clutches from one spawning event if there were no eggs in the tank beforehand. They are livebearers, and their fry will hatch after approximately 14 days (give or take a day or two).

It is possible to breed clown loach fish without having any adults present for this breeding event; however, it may be difficult because they tend to spawn at night when no one is watching. If you do not want to leave the lights on in your tank all night, it is possible to observe them spawning by using a blacklight.

Spawning will generally occur when there are more than five males present for every female. The male clown loach fish will chase the female around until she releases her eggs, and then he will fertilize them.

The eggs will hatch in about 14 days, and the fry will be free swimming at that time. The fry can be fed newly hatched baby brine shrimp or crushed flake food until they are big enough to eat the larger foods. It is important to provide a good variety of food for the fry so that they can develop into healthy adults.


Clown loach fish have an average lifespan of about 15-20 years in captivity if they are healthy and given a proper diet.

Parasites and diseases

Clown loach fish are susceptible to a variety of parasites and diseases, so it is important to keep an eye on them and treat any problems as soon as they are noticed. The most common parasites that affect them are ichthyophthirius (or white spot disease), costia, trichodina, and flukes.

Clown loach fish are also susceptible to bacterial infections, fungus, and constipation problems. If they develop any of these symptoms or diseases, they should be treated with an anti-parasitic or antibiotic medication immediately.


Clown loach fish are preyed upon by a variety of predators in the wild, including larger fish, birds, and reptiles. In captivity, they can be eaten by almost any other fish in the tank as well as some invertebrates (such as hermit crabs). It is important to keep this in mind when choosing tank mates for clown loach fish.

Are Clown loaches good community fish?

Do they make good pets?

Clown loach fish can make good pets if they are kept in a large enough tank and with appropriate water chemistry. They will eat the most common aquarium foods, but it is important to provide them with an algae-based diet for optimum health. Clown loaches do not school together like many other types of fish, so you should only keep one unless your tank is very large.

What fish are compatible with clown loaches?

Clown loaches are compatible with most tropical community fish, but you should avoid keeping them together if there is any chance of them growing larger than six inches. Some good tank mates for clown loaches include barbs (such as cherry barbs), danios, rasboras, smaller gouramis, and bettas, and loaches (such as kuhli loaches).

How many clown loaches should you keep together?

You should only keep one clown loach fish in a tank unless it is at least 30 gallons with plenty of hiding places. Two individuals may become aggressive towards each other if their aquarium is too small and they are kept together for an extended period of time, so be sure to provide them with plenty of space.


Clown loach fish are a great addition to any home aquarium. They can be very entertaining to watch, especially when they are spawning or eating. They need plenty of plants and hiding places in their tank so that they will feel comfortable enough to interact with you on occasion.
