Description

The banjo catfish (Bunocephalus coracoideus) is a remarkable small catfish of the family Aspredinidae from the Amazon basin in South America. The body has the shape of a banjo: a broad, strongly flattened front with head, followed by a thin, long tail. The rough, brown-mottled skin provides excellent camouflage among plant debris and leaves on the bottom. The species reaches about 11 cm and inhabits ponds and forest creeks rich in plant detritus. As a bottom dweller it feeds on a wide range of food, including organic material and small invertebrates. Owing to its peculiar shape it is popular in the aquarium trade.
