Labidochromis Caeruleus White

This species is a maternal mouthbrooder, meaning the eggs are carried, hatch, and develop in the mothers mouth (buccal cavity), for about three weeks. These fish are ovophiles and the male will excavate a pit in the sand within his territory, in which the female lays the eggs; the female then takes these eggs into her mouth for fertilization.
