Ecology
Freshwater; benthopelagic; pH range: 6.5 - 7.2; non-migratory. Tropical; 22°C - 30°C (Ref. 12468); 11°S - 21°S
Africa: two distinct population groups; a northern in the drainage systems of Lake Chad and the Chari River in Chad; Ubangi, Kotto, Bamingui and Gribingi river systems in Central African Republic; upper and middle White Nile in Sudan; Uele and Itimbiri in northern Democratic Republic of the Congo (Ref. 47311). Also in Wagenia Falls in Democratic Republic of the Congo (Ref. 106245). Southern populations are found in the Sankuru, Lake Mweru Wantipa and Lufira River in southeastern Democratic Republic of the Congo; Lake Mweru Wantipa and Lake Bangweulu in northern Zambia, and the upper Zambezi in western Zambia; upper Zambezi, Kwilu, upper Kasai and Kwando in Angola; Chobe River and Okavango swamps in Namibia and Botswana; lower Shire in southern Malawi; some river systems flowing into the Indian Ocean in Mozambique (Ref. 47311). Okavango and Pungwe-Buzi systems (Ref. 7248, 52193). Zimbabwe, South Africa (Ref. 27139).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 3.5 cm TL male/unsexed; (Ref. 52193)
Dorsal spines (total): 0; Dorsal soft rays (total): 7 - 9; Anal spines: 0; Anal soft rays: 11 - 16. Diagnosis: Lacustricola hutereaui is easily distinguished from L. chobensis and L. pygmaeus by the possession of a ventral arm in the posttemporal bone vs. ventral arm absent, a sharp ventral process in the maxilla vs. ventral process absent, retroarticular smaller than anguloarticular ventral arm vs. about the same size, a lachrymal without a posteroventral extension vs. posteroventral extension present, and by a sinuous cleithrum posterodorsal flap vs. flap rounded (Ref. 123968).
Found in small rivers, brooks, swamps and shallow lake parts among vegetated areas (Ref. 3788). Strictly a floodplain or marsh-loving species (Ref. 7248, 52193). Not a seasonal killifish (Ref. 27139). Is difficult to maintain in aquarium (Ref. 27139).
