Etymology: Chromidotilapia: Greek, chromis = a fish, perhaps a perch + Bechuana, African native thiape = fish (Ref. 45335); nana: Named in reference to the relatively small adult sixe of this species when compared with congeners (Ref. 50577).
Environment: milieu / climate zone / depth range / distribution range

Descrição suscinta
Morfologia | Morfometria
Espinhos dorsais (total): 14 - 15; Raios dorsais (total): 10-11; Espinhos anais 3; Raios anais : 8 - 9. Diagnosis: 15-17 rakers on first gill arch; 2 large rounded to slightly elongated spots on flanks usually visible, sometimes with 1-2 small dark spots between the large ones; lachrymal depth greater than 22% SL (Ref. 81260). Usually a single row of teeth in both jaws (Ref. 50577, 81260).
Usually found in small groups of up to ten individuals; prefers more open areas over sandy bottoms, but always remains near shelter; diet composed mainly of aufwuchs and detritus; sand and mud are also sifted for edible bits, as are the organic layers covering rocks and wood (Ref. 52307). Monogamous (Ref. 81260), pair bonding, ovophilic, biparental mouthbrooder (Ref. 52307, 81260).
Ciclo de vida ou comportamento de acasalamento
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
In aquaria, a monogamous, pair-bonding, biparental ovophilic mouth brooder. Eggs are deposited on hard substrate or on leaves and incubated by the female for the first 2 or 3 days; afterwhich incubation may be done by both male and female (but mainly by female) (Ref. 50577).
