Blue OB Peacock is aquarium strain derived from the peacock cichlids from Lake Malawi in eastern Africa. It is an aquarium strain of uncertain origin. We acquired this strain from a commercial source in 2003 and have selected for improved blue coloration. Males often reach 15cm (6 in.). Females are considerably smaller. Males are colorful with yellow-pink bodies and fins with bright blue mottling throughout. Females have a brown-gray background body coloration with yellow highlights and blackish mottling. This fish’s ancestors hail from Lake Malawi in eastern Africa.
