Description

Synodontis notatus is an upside-down catfish of the family Mochokidae found in fresh waters of the Congo basin in Central Africa. It grows to about 15-25 cm and has a fairly plain silvery-grey body usually marked with a single dark spot on the flank, which gives it its name. Distinctive features are the three pairs of barbels and the stout dorsal and pectoral fin spines. Like many Synodontis species it often swims upside down. A nocturnal omnivore, it feeds on insect larvae, molluscs, crustaceans and plant material. The species is popular in the aquarium hobby.
