Clown Loach Fish
If you’ve ever seen a school of clown loaches, it’s hard to resist bringing a few of them home. It’s even harder to imagine that this beautiful fish is eaten as food fish in Indonesia and Borneo, where it grows to over a foot in length. Fortunately for the clown loach, among aquarium enthusiasts, it’s a staple in the community tank rather than on the dining table. Its orange and black striped body, red fins, and active behavior have made it one of the most popular loach species for fishkeepers.
We cover all the essentials from setting up your aquarium, what to feed them, tank mates and much more.

Its orange and black striped body, red fins, and active behavior have made it one of the most popular loach species for fishkeepers. The clown loach is a peaceful fish and coexists well with nearly any tankmate. It is also an amusing species to watch and feed as it is very active during the day.Apr 10, 2020 Minimum Tank Size: 100 gallons PH: 6 – 7.5 Hardness: 5° to 15° dH Temperature: 75°F – 85°F (24°C – 29°C)
The clown loach is a peaceful fish and coexists well with nearly any tankmate. It is also an amusing species to watch and feed as it is very active during the day. Clown loaches will even eat any annoying snails that wind up in your aquarium. The clown loach is sometimes called a scaleless fish, but it actually does have small scales embedded in its skin.

Origin and Distribution
The clown loach hails from the rivers and tributaries of Malaysia, Borneo, Sumatra, and Kalimantan. During spawning periods, they migrate to flooded areas of the rainforest where soft, tea-colored water flows through boggy, slow-moving streams. This loach prefers waterways that are shaded by leafy plants and lined with plant detritus such as fallen leaves, twigs, and branches.
Colors and Markings
Like all loaches, the clown loach has a long, pointed nose surrounded by sensitive whisker-like barbels and a sharp spine beneath each eye. These spines are used for defense; in captivity, these may prick fingers or snag on nets, so it’s important to be careful when handling your loach.
The clown loach’s arched body is long and lean, ideal for cutting through the water. True to its name, its body is bright orange to yellow, and its fins and tail are bright red. It has two wide black V-shaped stripes along the sides of its body and a third black stripe running vertically through its eye.
Peaceful with its own and other species, the clown loach prefers to have companions with which it will form a school. Virtually all non-aggressive fish are suitable as tankmates. Because they prefer to live in groups, it’s wise to keep four or more in a tank. They don’t like bright light, will hide among plants or rocks as well, and sleep in holes, caves, and other hiding places.
Clown Loach Habitat and Care
Clown loaches are large schooling fish, and they are quite active. You will need a large tank with plenty of space for your loaches to move around. At the same time, however, each and every loach should have several hiding spots available; loaches love enclosed spaces and will sometimes “hide” in caves, tubes, and other hidey-holes. Hiding places can be made of wood or rock; strong, sturdy plants are also a good addition.
Unlike many loach species that are only active at night, the clown loach can be active during the daytime hours—though it’s likely to be most lively in the early morning and after dark. To watch your loach at play during waking hours, consider installing a blue “moonlight” tube or another form of bluish lighting, which will encourage your fish to come out to hunt.
Water quality is critical for keeping clown loaches healthy. Take care to keep the water very clean, well-aerated, and warm. An efficient filtration system and frequent water changes are critical. Tank lighting should be subdued, and the substrate should be soft and sandy.
Loaches are particularly prone to Ich infections; watch them closely whenever new fish or plants are added to the tank. In the unfortunate event that an infection does occur, keep in mind that loaches, like catfish, are very sensitive to some medications. Often dosages must be cut in half to be safe. Read product information carefully before treating any loach.
Clown Loach Diet and Feeding
Clowns will accept a wide variety of dry and live foods, but their preference is for live foods, especially worms. You can even feed them on earthworms, as long as you harvest the worms from soil that hasn’t been fertilized recently. Ideally, you should feed them several small meals throughout the day.Feeding Your Fish Live Food
Males can be identified by the tail, which is larger, forming a more pointed V-shape, and is more brightly colored. There are very few documented cases of clown loaches breeding in captivity. As a result, very little information is known about their breeding habits and needs.
Breeding the Clown Loach
Clown loaches rarely or never breed in captivity. If a female does spawn in an aquarium setting, there is an excellent chance that they will not be fertilized and that she or her male counterparts will eat the eggs before they hatch.
Virtually all clown loaches sold for aquaria are captured in the wild. It’s important when buying clown loaches to select only those with bright colors and those fish that are at least a few inches long. At the store, look carefully at the tank to be sure it is well kept and that the fish seem comfortable and healthy. If you see any dead fish, steer clear of the tank system; there is a good chance you’ll be buying a loach that is already infected with Ich.
This species was first described in 1852 by Dr. Pieter Bleeker when it was given the name Cobitis macracanthus. Since their discovery, Clown Loaches have been renamed twice.
In 1989 it was changed to Botia macracanthus and in 2004 Dr. Maurice Kottelat’s work led to this fish being given its own genus (Chromobotia) and being renamed Chromobotia macracanthus.
The Clown Loach is a tropical freshwater fish species of the family Botiidae. They are native to the Indonesian islands of Borneo and Sumatra.
They live in the flowing rivers for most of the year and at the start of the monsoon season retreat further upstream and inhabit smaller streams that are full of plant life to spawn and give rise to the next generation of these intriguing fish.
This species has been extensively harvested from their natural environment for the aquarium industry for at least the past few decades.
Although, they are still relatively abundant across their home range.
These fish tend to live for up to ten years.
They can be purchased from most local pet stores for around $9 each, but most places offer a slight discount when purchased in shoals.
Clown Loaches are an extremely social and peaceful fish that are often found closely foraging in the substrate.
They are best kept in large community tanks in a shoal containing at least 5 individuals. If you keep less than 5 you will find them to be very timid and shy, spending most of their time hiding.
These fish are playful by nature and enjoy chasing each other around the tank.
They have strange behaviors and can often be found lying on their side at the bottom of the tank appearing dead – don’t worry this is completely normal behavior for them.
These fish have a complex hierarchy and usually a female alpha. The younger fish tend to shadow the alpha, copying their behaviors and movements.
Their bodies are laterally compressed and have a deeply forked caudal (tail) fin which propels them through the water.
Clown Loaches do not have scales, but instead, produce a mucus layer for protection.
This species is orange, with three black bars. One over the head and eyes like a mask, one across the dorsal fin towards the caudal fin and the other is between those two.
Whilst the possession of black dorsoventral bars is usually an indicator of aggression, this is certainly not the case for this playful and friendly species.
Clown Loaches have two pairs of barbels on their snout to help them sift through the substrate to search for food. They also have a lateral line system (like most fish) which senses changes in water pressure and alerts the fish to possible predators.
In the wild, there are two genetically separate populations from Sumatra and Borneo.
The Sumatran populations have reddish-orange pectoral fins, whereas fish from Borneo have fins with black pigmentation.
An albino/platinum form is also present in this species, although it is rare. This color morph still has the orange background coloration, but the black bars are replaced by white ones.
Clown Loach Size
Clown Loach can grow up to 12 inches, however, as juveniles, they are around 2-3 inches in length.
Loach Fish Habitat and Tank Conditions
In the wild, these fish live in clear slow-flowing rivers and streams of the islands. During the monsoon season, they migrate upstream and into flood plains that are full of plant life, both floating and submerged.
At the peak of the monsoon season is when these fish spawn in small streams and flood plains.
The waters they occupy range in temperature from 77-86°F and have a pH of 6-8. These fish prefer subdued lighting and choose to live in areas where there is a lot of floating and overhanging plant life, or areas where river banks overhang.
These areas also provide the fish with cover from predation and can reduce the stress levels of the fish. These kinds of areas will be essential in the tank.
The rivers are made up of a rocky pebble substrate and the flood plains contain muddy substrate with plenty of growing plants.
In the aquarium, you may want to provide a mixture of substrates like pebbles as well as sand to give the tank a more natural feel.
Submerged plants are also essential and hardy species like Amazon Sword plants would be a perfect match for Clown Loaches.
These plants not only provide the aquarium with shade but also aid in aerating your tank through producing oxygen. They also provide a form of filtration as well as areas to play and hide.
The water temperature of the tank should be set as close as possible to the upper tolerance limits (86°F), as they tend to survive longer at higher temperatures and are less susceptible to diseases like Ich.
The water pH should always be maintained at an optimal range of 7.4-7.8, although slight fluctuation between 7 and 8 will be fine.
As with most aquariums, you will also need a heater and filter.
Clown Loach Tank Size
A group of these Loaches should be kept in a minimum 75 gallon aquarium as juveniles.
5 adults will need at least a 150 gallon tank – allow roughly 30 gallons of water per loach.
Clown Loach Tank Mates
In their natural habitat, they can be found in the same waters as Tiger Barbs, Hard-lipped Barb, Spotted Eel-Loach, Barred Rainbowfish, Comb-Spined Catfish and even Asian Arowana.
Other good tank mates for this species would be other bottom-dwelling fish such as Kuhli Loach, Bristlenose Pleco, and the Borneo Sucking Loach.
Species of Cichlids can also be kept with Clown Loach providing they are non-aggressive and share roughly the same water parameters.
The Bolivian Ram and other South American Cichlids like Angelfish and Leopard Pigeon Discus are all great examples.
A good invertebrate tank mate would be species of freshwater lobster or crayfish like the Blue Lobster and even freshwater crabs like the Red-Clawed Crab (providing they are kept in a paludarium as it is not a fully aquatic species).
You should always avoid keeping Clown Loach with any predatory fish.
Keeping Clown Loaches Together
It is highly recommended that these fish are kept in social groups due to their pack mentality. Being kept on their own will cause them to become shy and they will spend most of their time hiding.
Being kept in groups of 5 or more will cause a dramatic shift in their behavior causing them to become extremely active in the mid and lower levels of the tank.
Clown Loach Care Guide
As with most species of Loach, they are extremely susceptible to Ich (also known as White Spot Disease).
This is an ectoparasite that burrows into the gills and skin of fish and can also lead to fungal and bacterial infections. Loaches are usually the first fish to become infected due to them not having scales.
It can be extremely hard to spot during the early stages, but as it progresses you will notice your fish scratching against the sediment and ornaments.
Once identified, fish should be removed from the aquarium and placed in a separate quarantine tank for a month or so.
Whilst in quarantine fish should be treated for Ich using chemicals like Copper sulphate or Formalin based medications.
Alternatively, your local pet and aquarium stores will sell Ich cures over the counter.
Remember good water quality is essential for Clown Loach, so be sure to keep on top of all weekly water changes and tests, as this fish is sensitive to nitrates.
Tri-weekly gravel/substrate vacuums will remove parasitic spores from the aquarium. And water temperatures should always be kept at the upper level of the Loach’s tolerance limits (86°F).
What Do Clown Loaches Eat?
In the wild, this omnivorous species feeds on invertebrates like worms, crustaceans, and small water-dwelling snails. In addition, they also feed on decaying plant matter and algae.
Their dietary requirements can be met in your home aquarium quite easily.
You should feed them a mixed diet of sinking shrimp pellets and algae wafers. They will also do a great job of eating any leftover fish flakes which sink to the bottom of the tank.
Frozen foods like shrimp and blood worms will support the healthy growth of the fish but should only be fed a few times a week.
Live foods like bloodworms, earthworms and small shrimp are considered a delicacy to Clown Loach and should be fed once a week as a treat.
These fish also love snails and we certainly recommend that you feed snails to your Loach.
You could set up a separate smaller tank and begin breeding snails as live food for your Loach which we are sure they would greatly appreciate. If not, snails are readily available at local fish stores or can be purchased online and delivered to your door.
Feed your fish small amounts of food, two times a day and make sure that there is no waste.
Clown Loach Breeding
These fish are not the easiest fish to breed and even expert fish keepers can find it difficult.
For the best chance of breeding success, we recommend you follow the steps outlined below.
First, you must find a sexually mature pair (around 6 inches in length). Keep them in separate tanks for a few weeks and feed them highly nutritious foods. Females will appear to have a larger width during this period indicating the production of roe.
When the female appears larger, the male and female should be placed in an aquarium with lots of plants and excellent water quality.
A water temperature of 77.9-79.7°F is essential and a pH of 6.2-6.4 is the optimal range for breeding and hatching.
When the female has released her eggs and the male has fertilized them, the male and female should be removed to avoid them eating the eggs.
Fertile eggs will be a pink color and will move and wriggle – infertile eggs will turn brown.
If successfully hatched, the tiny fry can be fed live cultivated infusoria. As they begin to grow, they should be moved onto baby brine shrimp, tubifex worms and even ground-up fish flake food.
Are Clown Loaches Suitable For Your Aquarium? (Summary)
Clown Loach is an extremely social species and would make a great addition to any community tank.
They are best kept by people with previous fish keeping experience, due to the fact they are more susceptible to diseases than other aquarium fish.
You will notice they enjoy spending most of their time in the lower levels of the aquarium, eating leftover foods. They are like a pack of aquarium puppy dogs, chasing and playing with one another throughout the day.
