Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic. Tropical
Africa: Cubango, Cunene, Okavango (Ref. 42019) and Cuanza (Ref. 42019, 120641). Also known from the Luembé (Kasai tributary, middle Congo River basin) in Angola (Ref. 42019).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00531 - 0.02721), b=2.99 (2.81 - 3.17), 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
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
