Description

The blackskin catfish is an Asian air-breathing catfish of the family Clariidae from Southeast Asia. The species grows to about 35 cm and has the elongate, dark body characteristic of Clarias with a flattened head, barbels and long, continuous dorsal and anal fins. It inhabits lowland swamps, peatlands and standing waters with slightly acidic water. Thanks to an accessory breathing organ it can gulp air and survive in oxygen-poor water or briefly on land. As an omnivore it eats bottom animals, insects and plant matter. The stout pectoral spines can cause painful injuries.
