Aulonocara stuartgranti ‘Mbenji Blue Regal’ is a peacock cichlid species from Lake Malawi in eastern Africa. This fish is also known as Aulonocara koningsi. I’m researching the name, but https://www.itis.gov/ does not recognize the latter name as yet. Our strain is from a commercial source. We acquired the strain in from Fish Gallery in July 2012. Males often reach 15cm (6 in.). Females are considerably smaller. Males are colorful with blue faces and body with orange squiggles in the caudal (tail). Fins except for the ventral fins are blue. Females are drab brownish-gray fish with very faint black vertical bars on the bodies. This fish hails from Mbenji Island in Lake Malawi in eastern Africa.
