Description

The silver tandan is an eeltail catfish (Plotosidae) from fresh water of northern Australia and New Guinea. The species grows to about 25 cm and has an eel-like, silver-grey body in which the second dorsal, tail and anal fins are fused into a long border, with barbels around the mouth. As a bottom-dweller it searches over sand and mud of rivers and pools for insect larvae, crustaceans and worms. The dorsal and pectoral spines are venomous and can give a painful puncture wound.
