Pseudotropheus crabro is a mbuna cichlid from Lake Malawi in eastern Africa.This fish has been called Melanochromis crabro and M. ornatus. Our strain is from a commercial source. We acquired the strain in 2003. Males often reach 12.5cm (6 in.). Females are somewhat smaller. Males are, unusually for cichlids, the drab sex, with a purplish gray coloration with faint black bars. Some males sport a few blue flecks in the “shoulder” area. Females have yellow-gold bodies with faint dark bars and yellow fins. Juveniles of both sexes sport the adult female color pattern. This fish hails from Lake Malawi in eastern Africa.
