Globular swelling on chin reduced. Base of dorsal fin 0.51-0.78 x of the anal fin base. Generally uniformly silver color but may sometimes be irregularly mottled on the sides.
Distribution area is mainly continental and it is rarely found in the lower courses of basins (Ref. 81274). Inhabits fringing vegetation in the Sudd and migrates onto the floodplain to spawn (Ref. 28714). Bottom feeding insectivore (Ref. 28714). It possesses electro receptors over the entire head, the dorsal and ventral regions of the body, but absent from the side and the caudal peduncle where the electric organ is located (Ref. 10011). Also sensitive to sound frequencies (Ref. 10831).
