Labidochromis Caeruleus

Labidochromis caeruleus is a species of cichlid fish that is endemic to the central western coastal region of Lake Malawi in East Africa. It is also known as lemon yellow lab, the blue streak hap, the electric yellow or yellow prince, depending on the colour morph. A naturally occurring yellow-coloured variant from Lion's Cove is one of the most popular cichlids amongst aquarium hobbyists.

This species is a maternal mouthbrooder, meaning the eggs are carried, hatch, and develop in the mother’s 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.

Electric yellows inhabit water with a pH between 7.8 and 8.9 and an ideal temperature range of 23–26 °C (73.4–78.8 °F).
