Common in a broad range of habitats from mainstream margins to floodplain channels and lagoons; preys on insects and small fish, including mormyrids and barbs, which are taken near the bottom; breeds in spring and early summer at low water before the annual floods arrive; relatively few eggs are laid and mouthbrooded; matures after 1-2 years (Ref. 7248). Agamous, maternal mouthbrooder (Ref. 52307). Also caught with drawnets.
A mouth brooding species.

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00778 - 0.02339), b=3.03 (2.88 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 4.2 ±0.71 se; based on food items.
Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
устойчивость к внешним воздействиям (Ref.
