Description

The African squeaker is a scaleless catfish of the family Mochokidae reaching about 33 cm. The sturdy, brownish body is scattered with dark spots and carries three pairs of barbels around the downturned mouth, an adipose fin and strong, serrated spines in the dorsal and pectoral fins. With those pectoral spines the fish can make a grinding, 'squeaking' sound. The species is native to the rivers of West and Central Africa and is known outside Africa mainly as an aquarium fish. It is active at night and feeds as an omnivore on invertebrates, plant matter and detritus from the bottom. It reproduces in the rainy season when rivers flood.
