Pelvicachromis pulcher is a freshwater fish of the cichlid family, endemic to Nigeria and Cameroon. The species is popular amongst aquarium hobbyists, and is most commonly sold under the name kribensis, although the species has other common names, including various derivatives of kribensis: krib, common krib and rainbow krib, along with rainbow cichlid and purple cichlid. Originally P. kribnesis, its Latin name was changed to P. pulcher. Pulcher is Latin for "beautiful". The species is a popular cichlid for the aquarium. In the wild, male P. pulcher grow to a maximum length of approximately 12.5 cm (4.9 in.) and a maximum weight of 9.5 g. Females are smaller and deeper bodied, growing to a maximum length of 8.1 cm (3.2 in.) and a maximum weight of 9.4 g. Both sexes have a dark longitudinal stripe that runs from the caudal fin to the mouth and pink to red abdomens, the intensity of which changes during courtship and breeding. The dorsal and caudal fins also may bear gold-ringed eye spots or ocelli. (Read more...)
