Description

The Spotfin bagrid is a bagrid catfish (Bagridae) from fresh water of the Mekong and Chao Phraya basins in Southeast Asia. The species grows to about 30 cm and has an elongate, grey-brown body with long barbels, an adipose fin and stout, serrated spines in the dorsal and pectoral fins. As a nocturnal bottom predator it searches rivers for insect larvae, worms, crustaceans and small fish. The fin spines carry a mild venom and can give a painful puncture wound.
