Length at first maturity / Size / Weight / Age

Maturity: L_m 17.5, range 15 - 20 cm
Max length : 35.0 cm SL male/unsexed; (Ref. 7248); max. published weight: 1.5 kg (Ref. 5693); max. reported age: 6 years (Ref. 7248)

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.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.00804 - 0.02483), b=3.02 (2.88 - 3.16), 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.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2; tmax=5.5).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).

Price category (Ref. 80766): Unknown.
