Seems to prefer sheltered areas near riverbanks; diet mainly consists of detritus, aufwuchs, shrimp eggs and small insects (Ref. 52307). Monogamous (Ref. 47112), pair bounding female larvophilic mouth brooder, which spawns in caves (Ref. 47112, 52307, 81260).
Life cycle and mating behavior
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
Chromidotilapia mrac is a monogamous, pair bounding female larvophilic mouthbrooder, which spawns in caves (Ref. 47112). Eggs are incubated by the female alone for 3 days, after hatching the larvae are carried by the female for 9-10 days in the buccal cavity (Ref. 47112). When free swimming the juveniles are protected by the adults for a duration of about 4-5 weeks (Ref. 47112).
