Description

The Congo spiny eel is an eel-shaped freshwater fish of the family Mastacembelidae (spiny eels) reaching about 44 cm. The elongate, brown-marbled body has an extended, mobile, pointed snout with which the fish probes the bottom for prey, and a row of separate, short spines before the soft dorsal fin (hence 'spiny eel'). The species comes from the Congo basin in Central Africa and lives in slow to flowing water with soft or vegetated bottoms, where it buries itself half in the sand or among plants by day. At night it searches for insect larvae, worms and small crustaceans. For its unusual shape it is popular in the aquarium hobby, and locally it is a valued food fish.
