Etymology: Zaireichthys: Composed form Zaire river + Greek,ichtys = fish; the habitat of this fish (Ref. 45335).
Environment / Climate / Range
Freshwater; demersal; dH range: 20 - ?. Tropical; 22°C - 25°C (Ref. 2059), preferred ?; 11°S - 22°S
Africa: Lake Victoria, Rufiji and Lake Rukwa systems (Ref. 78218), questionably in Tana River in Kenya (Ref. 52331). Also in the Cunene, Okavango, Zambezi, Pungwe, Buzi, Save systems as well as in the Lake Malawi catchment (Ref. 7248). Presence in the Congo basin questionable (Ref. 51287, 58032, 78218). As it currently stands, this species probably represents a complex of several different species (Ref. 7248).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.8 cm SL male/unsexed; (Ref. 51287)
soft rays: 11 - 13;
Vertebrae: 35 - 38. This species differs from Zaireichthys lacustris and Z. maravensis in possessing a premaxillary tooth patch that is less than 40% of the mouth width; it has shorter barbels than Z. wamiensis, 0.9-1.3 in head length vs. 0.7-0.9 in head length; and it is distinguished from Z. compactus by a higher number of branched pectoral-fin rays, 7 cf. 6 (Ref. 86935). Caudal fin slightly emarginate, with the lower lobe a little longer than the upper, the upper and lower lobes each with seven or eight branched rays (Ref. 86935). Humeral process of cleithrum extending to between level of end of supraoccipital process and base of dorsal fin (Ref. 86935). Colour is generally yellowish brown with a series of about nine faint dark blotches along centre of flank and traces of additional series above and below (Ref. 86935).
Inhabits fairly shallow water (Ref. 13337). Occurs over sand, usually buried with just the eyes protruding. Feeds on minute organisms. Eggs few (12-16) and large (3-5 mm diameter) suggesting possible parental care (Ref. 7248).
