The Kuhlii Loach is one of about 100 species in the Cobitidae family. Loaches are bottom dwelling scavengers with reduced or absent scales and a mouth surrounded by barbels used to taste. At times, the loach will lie on its side when there are insufficient hiding places, giving the impression that it is sick; this behavior is normal.
Largely nocturnal, loaches are shy fish that like to hide among driftwood, plant roots, rocks, and caves. Loaches are peaceful fish that get along well with other peaceful community tank mates.
Unfortunately, the breeding habits of the Black Kuhlii Loach have not been documented.
