Description

Greshoff's squeaker is a brown, mottled catfish of the family Mochokidae (squeakers) reaching about 27 cm. The sturdy body has three pairs of barbels around the inferior mouth, a large adipose fin and stout, lockable spines in the pectoral and dorsal fins. Like other squeakers it can make a squeaking or grating sound with its pectoral spines. The species comes from the Congo basin in Central Africa and lives on soft bottoms of slow water of rivers and creeks. Mainly at night it probes the bottom with its barbels for insect larvae, molluscs, crustaceans, algae and detritus. For its size and behaviour it is popular in the aquarium hobby; when handling, the sharp fin spines call for care.
