About the Botiidae family botiid loach family
Botiidae are the botiid loaches, elongated, active bottom-dwellers from South and Southeast Asia that include the clown loach, yoyo loach and dwarf chain loach. They are social, playful and intelligent, best kept in groups where they form a lively pecking order, and many are enthusiastic snail-eaters. They prefer clean, well-oxygenated water with plenty of caves, and larger species like the clown loach need big tanks as they grow.
Keep botiid loaches in a group of five or more with soft sand, caves and driftwood, and stable, well-oxygenated water — they are sensitive to poor conditions and prone to whitespot when stressed.
Breeding
Egg-scatterer (rarely bred in aquaria)Botiid loaches are egg-scatterers that are very difficult to breed at home; most in the trade are commercially hormone-induced or wild-caught. They mature slowly and rarely spawn in ordinary aquarium conditions, so hobby breeding is uncommon and not something to rely on.
