The Labidochromis caeruleus, known as the Lemon Cichlid or electric yellow, was classified by Fryer in 1956. It gets its scientific name from the blue-sky colour of the first specimens caught in Lake Malawi, later the so-called yellow specimen was discovered.
In the wild, Lemon Cichlids are not territorial at all and just meander amongst the rocks without a "home". They are not very aggressive either, being considered one of the most peace-loving fish. Depending on the area where they live, there may be fry of other fish, invertebrates, small crustaceans and insect larvae, or even snails.
