Perissodus microlepis
Template:Short description Template:Speciesbox
Perissodus microlepis is a species of cichlid endemic to Lake Tanganyika. It can also be found in the aquarium trade.[1] This species reaches a length of Script error: No such module "convert". TL. It is a scale-eating 'parasite' on other fish species. It occurs in two distinct morphological forms. One morph has mouth parts twisted to the left, enabling it to eat scales off its victim's right flank. In contrast, the other morph, whose mouth is twisted to the right, eats scales off its victim's left flank. The relative abundance of the two morphs in populations is regulated by frequency-dependent selection.[2][3][4][5]
