Biology

provided by Fishbase
Type specimens were collected in small coastal streams flowing through well-preserved Atlantic forest; in localities between 100 and 370 m a.s.l., always in rocky substrate with fast flowing, clear water, under direct sunlight, and depths between 10 and 50 cm. Underwater observations indicate that this species is most active during the night, grazing on the bottom (Ref. 57859).

Hemipsilichthys nimius

provided by wikipedia EN

Hemipsilichthys nimius is a species of catfish belonging to the family Loricariidae. The species is only known from two small rivers in Rio de Janeiro State, Brazil: the Perequê-Áçu and the Taquari.

This is a fairly typical loricariid with a broad head and large mouth used for adhesion to rocks in fast-flowing water. Colouring is generally pale brown with darker blotches with standard length up to 10.5 centimetres (4.1 in). It can be distinguished from all its congeners by the anatomy of the dorsal fin: eight branched rays are present instead of seven and there is a membrane connecting the last ray to the back of the fish.
