Description

The threadfin catfish is a small African catfish of the family Claroteidae endemic to Lake Tanganyika in East Africa. The species grows to about 9 cm and has a stocky body with conspicuously long, thread-like barbels, to which the name refers, and stout fin spines. It inhabits inshore waters to about 20 metres, often among stones. As a bottom searcher it feeds on small invertebrates. Notable is its biparental mouthbrooding: both male and female can incubate the eggs in the mouth. The sharp fin spines can prick; therefore handle the fish with care.
