Description

The blackfin gagata is a sisorid catfish (Sisoridae) from fast-flowing, turbid rivers of South Asia, including the Ganges and Brahmaputra systems. The species grows to about 12 cm and has a slender, flattened, silver-grey body with dark fins, barbels and a groove on the chest with which it clings to the bottom. As a bottom-dweller it moves in schools over sand and gravel and snaps at insect larvae and small invertebrates. The stout pectoral spines can give a painful puncture wound when handled.
