Size 60mm (2.4") SL. Find near, nearer or same sized spp.
Identification All species in the genus Synodontis have a hardened head cap that has attached a process (humeral process) which is situated behind the gill opening and pointed towards the posterior. The dorsal fin and pectoral fins have a hardened first ray which is serrated. Caudal fin is always forked. There is one pair of maxillary barbels, sometimes having membranes and occasionally branched. The two pairs of mandibular barbels are often branched and can have nodes attached. The cone-shaped teeth in the upper jaw are short. S-shaped and movable in the lower jaw. These fish produce audible sounds when disturbed rubbing the base of the pectoral spine against the pectoral girdle.

It is very similar in colour pattern to the more commonly encountered Synodontis nigriventris. The main differences being that S. contracta has a bigger head, broader mouth and far larger eye.
Sexing Unknown, hard to tell differences in genital papillae in such a small species.
General Remarks Males reach no larger than 70mm SL.

Furniture Well planted tank would best suit this fish as it lives in this type of habitat in the wild over muddy substrate.
Compatibility A peaceful species even with its own kind.
Suggested Tankmates Most small to medium sized community fishes. African tetras would be the most appropriate. This species is found in large shoals in the wild and should be kept in a group of at least 3 or 4 individuals preferably more.
Breeding Although not hatched, at least one aquarium spawning has been encountered. A small group produced one batch of thirty, large (3.0 mm diameter) bright orange eggs, these were hidden away at the back of the tank.
