Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Africa: Chiloango basin and Dja River (middle Congo River basin)(Ref. 81639). Also reported from the Niari (Ref. 53765) and Loeme (Ref. 81639) but this needs confirmation. Report from the Inkisi (lower Congo River basin) based on a misidentification (Ref. 88779). Report from Eala (Ruki drainage in Democratic Republic of the Congo)(Ref. 41591) needs confirmation.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00251 - 0.02399), b=3.04 (2.79 - 3.29), 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. 69278
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (52 of 100) .
