Description

The Blackspotted synodontis is an African synodontis catfish (Mochokidae) from fresh water of the Tanganyika and Zambezi systems in southern and eastern Africa. The species grows to about 35 cm and has a stocky body with a bony head, three pairs of barbels and stout, serrated dorsal and pectoral spines that lock upright. The body is grey-brown with numerous black spots. As a nocturnal bottom-dweller it searches for insect larvae, molluscs, algae and detritus; some species like to swim upside down. The fin spines carry a mild venom and can give a painful puncture wound.
