General: Clown loaches are a well known fish in the hobby and have very amusing personalities. They are extremely social fish and prefer to be kept in groups. Clown loaches do best in aquariums with significant water flow that provides oxygenated water. Clown loaches will venture out into the open aquarium if the tank is outfitted with dim lighting, which mimics their natural habitat. Therefore, if you want live plants in the aquarium, choose species that can tolerate low light conditions. Clown loaches do have a tendency to nibble on plants, so choose durable species. Clown loaches like a sandy substrate for scavenging supplemented with sufficient structure in the aquarium to provide hiding spots.

Dimorphism: Female clown loaches are slightly larger than males, and males have a tail that slightly curves inwards, while a female's tail is straight.

Fecundity: Breeding clown loaches in the home aquarium has not yet been documented.

Water chemistry: 72-86° F, KH 8-12, pH 6.0-7.5

Aquarium Diet: Clown loaches are not overly picky eaters and will gladly accept frozen or live brine shrimp and blood worms, algae wafers, fresh vegetables such as cucumber slices, fish flake, and live snails.

Compatibility: Good tankmates for clown loaches include other clown loaches, tetras such as diamond tetras (Moenkhausia pittieri) or pristella tetras (Pristella maxillaris), rainbowfish such as the boesemani rainbowfish (Melanotaenia boesemani), rasboras such as the redtail rasbora (Rasbora borapetensis), gouramis such as the pearl gourami (Trichopodus leerii), and peaceful barbs such as the cherry barb (Puntius titteya) . Fish that should be avoided include those with long, fancy fins such as angelfish (Pterophyllum sp.) and guppies (Poecilia reticulata).
