背棘 (总数) : 0; 背的软条 (总数) : 14 - 20; 臀棘: 0; 臀鳍软条: 24 - 30. LS/D 2.9-4.3;LS/PD 10.8-15.5. Pectoral fin longer or at least as long as head. 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.
LS/D 2.9-4.3;LS/PD 10.8-15.5. 胸鳍更长的或至少长达头部。 在下巴上的球状的膨胀缩小的。 背鳍基底 0.51-0.78 倍于臀鳍基底。 通常均匀银色的颜色有时但是可能是有不规则斑点侧边上。
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).
栖息于浮游植物堆的岸边的植丛而且回游到上面洪泛区产卵。 底部摄取食物的食虫动物。 (参考文献 28714) 持有在整个头，背部与腹面身体的区域上的电容器, 但是发电器官所在的体侧与尾梗没有出现.(参考文献 10011) 也敏感声音频率。 (参考文献 10831)
