Description
The longtail spiny eel is a long, eel-like freshwater fish of the family Mastacembelidae (spiny eels) reaching about 40 cm. The brown, marbled body is strongly elongate and ends in a pointed, mobile snout with which the fish probes among stones and in the bottom for prey. A row of separate, sharp spinelets stands before the soft-rayed dorsal fin. By day it often buries itself in sand or mud with only the snout showing; at night it emerges to hunt insect larvae, worms and small crustaceans. The species comes from Central and East Africa, including the Congo and Zambezi basins and the great lakes. Because of its snake-like shape it is popular in the aquarium hobby.
