Fin's Fish Guide
The Black catfish (Neosilurus ater) is a freshwater fish of the family Plotosidae that grows up to 47 cm.
Description
The black catfish is an eeltail catfish of the family Plotosidae from Australia and New Guinea. The species grows to about 47 cm and has an elongate, dark body with barbels and an eel-like tail in which the dorsal, tail and anal fins merge. It lives in rivers and smaller streams, usually where the current is relatively swift, and sometimes moves in schools. As a bottom searcher it feeds on insect larvae, crustaceans, molluscs and detritus. The first pectoral and dorsal spines bear venom glands; a sting gives a severely painful wound, so handle the fish with care.
