Etymology: Sargochromis: Greek, sargos = sargus + see under Chromis. More on author: Boulenger.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C - ; 11°S - 21°S
Africa: Okavango River, upper Zambezi River, Lake Kariba and the Kafue River (Angola, Namibia, Botswana, Zambia and Zimbabwe).
Length at first maturity / Size / Weight / Age
Maturity: Lm 11.3, range 10 - 12.5 cm
Max length : 34.5 cm SL male/unsexed; (Ref. 13337); max. published weight: 1.0 kg (Ref. 7248); max. reported age: 6 years (Ref. 7248)
Favors deep permanent floodplain channel and lagoons, with sandy bottom and vegetation (Ref. 7248, 52307). Feeds on aquatic insects, crustaceans and snails (Ref. 7248). Ovophilic, agamous (Ref. 52307) female mouthbrooder (Ref. 7248, 52307). Males construct a nest where the eggs are initially laid; mature at 10-12 cm length; useful snail control agent (Ref. 7248).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00880 - 0.03939), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.54 se; based on food items.
Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2; tmax=5.5).
Vulnerability (Ref. 59153
): Low vulnerability (21 of 100) .
