Africa: endemic to but widely distributed in the Congo River basin (Ref. 41594, 42019, 42510, 44840, 45616, 46233, 46253, 80450) in Democratic Republic of the Congo (Ref. 42019), Republic of Congo (Ref. 44840), Cameroon (Ref. 46233) and the Central African Republic (Ref. 80450). Report from the Malagarasi in Tanzania probably based on a misidentification (Ref. 42019).

Descrição breve
Chaves de identificação | Morfologia | Morfometria
Raios dorsais moles (total) : 10 - 11; Raios anais moles: 17 - 19. Diagnosis: very well developed adipose eyelid; 17-19 anal-fin rays (III, 14-16); 17-20 gill rakers on lower limb of first gill arch; 39-43 lateral line scales; dorsal-fin origin at about same level of pelvic-fin insertions (Ref. 42019).
Body shape (shape guide): fusiform / normal.
Omnivore; remnants of small fish, fruits (Ref. 4910), aquatic and terrestrial insects and vegetation (Ref. 4910, 41580) found in stomach. Found in schools, can frequently be seen jumping above water surface (Ref. 41594). Very similar to A. macrophthalmus (Ref. 42019, 42480).
