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).

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 10 - 11; Anal soft rays: 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).

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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00331 - 0.01379), b=3.12 (2.94 - 3.30), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).
