Open encyclopedia reference
Labidochromis caeruleus is a species of cichlid endemic to the central western coastal region of Lake Malawi in East Africa. It has many common names, such as lemon yellow lab, the blue streak hap, the electric yellow or yellow prince, depending on the colour morph. The naturally occurring yellow-coloured variant from Lion's Cove is one of the most popular cichlids amongst aquarium hobbyists.
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). Large males may reach 15 centimetres (5.9 in) in length.
