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).
Chromidotilapia mrac 是一个一夫一妻的, 配对跳跃雌性的 larvophilic 口孵鱼, 这在洞穴中产卵。 (参考文献 47112)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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。
