; süßwasser demersal. Tropical
Africa: widespread in the Congo River basin in Democratic Republic of the Congo (Ref. 42493), Republic of Congo (Ref. 44840), Central African Republic (Ref. 45441) and Angola (Ref. 11970, 120641). Also in the lake Tanganyika basin (Ref. 36899), but apparently only in lower courses of tributary rivers, including the Malagarasi (Ref. 54847), and not in the lake itself (Ref. 36901). Reports from the Sanaga (Ref. 51193) and Benue (Ref. 42497) in Cameroon questionable and unconfirmed (Ref. 81274, 81635).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01380 (0.00615 - 0.03096), b=2.86 (2.69 - 3.03), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (11 of 100).
