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).非洲: 加彭。
