Labidochromis
Labidochromis is a genus of cichlid fishes that are endemic to Lake Malawi in East Africa. The genus includes 18 formally described species, and several yet undescribed species. It includes a number of species commonly kept in cichlid aquariums such as L. caeruleus (electric yellow). The species in this genus can easily hybridize, so if kept in an aquarium it is recommended to only have one species from this genus.
