Pelvicachromis taeniatus is a species of cichlid from Nigeria that is occasionally kept as an aquarium fish. It is native to the soft-water rivers. This species can reach a length of 7.1 centimetres (2.8 in) SL.[2] It is known to exist in a variety of geographically restricted varieties distinguished by differences in coloration. These are often given names such as "Nigerian red" or "Moliwe" that refer to the places where each variety is collected.
P. taenuatus formerly included populations from Cameroon. A 2014 study by Lamboj, Bartel & dell’Ampio found that the Cameroon populations were a different species from the Nigeria populations, and identified the Cameroon populations as the species Pelvicachromis kribensis.[3]
Courtship
During courtship females display a large and visually arresting purple pelvic fin as a sexual ornament (see image left). "The researchers found that males clearly preferred females with a larger pelvic fin and that pelvic fins grew in a more disproportionate way than other fins on female fish."[4][5]
