Description

The granulose squeaker is a squeaker catfish (Mochokidae) endemic to Lake Tanganyika in East Africa. The species reaches about 27 cm and owes its name to the strikingly granular skin; the black body bears white spots and the fins have white margins. With three pairs of barbels it probes the bottom. It feeds on algae, sponge particles, molluscs and small invertebrates. The stout, lockable pectoral and dorsal fin spines can cause puncture wounds when handled. Owing to its handsome appearance the species is highly sought after in the aquarium trade, which puts pressure on the wild population.
