Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical
Africa: widespread in West-Central Africa (Ref. 81639). Also known from the Dja River (middle Congo River basin)(Ref. 81639) and the Cross River in Cameroon (Ref. 51193, 81282). Reported from around Dundo (middle Congo River basin, Angola) (Ref. 81639), but questionable as specimens are identified as Barbus sp. aff. progenys (Ref. 11970).

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=0.00437 (0.00201 - 0.00949), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.5 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).
