Melanochromis joanjohnsonae 'exasperatus' is a mbuna cichlid from Lake Malawi in eastern Africa. (Click here for a general discussion of cichlids.) This fish is also known as Melanochromis exasperatus and Labidochromis fryeri. The top photo is of a mature male. The bottom picture is a mature female. We acquired our stock in 2003 from a commercial source.

Size: Males often reach 12.5cm (6 in.). Females are somewhat smaller.

Environment: This fish tolerates pHs from 6.5 to 8.0 while preferring pHs at near the higher end (basic) of this range. Water hardness is not critical, but it prefers very hard water. Optimum temperature ranges from 20-30°C (68-85°F).

Temperament: This fish is not aggressive for a cichlid, but males can be quarrelsome among themselves. They are active fish, constantly interacting with other fish. It can be kept either in a large single species aquarium or in active community aquaria with fish with similar behavior and requirements.

Spawning: This cichlid breeds like other members of its genus. It is a maternal mouth brooder. At 30°C (85°F), females carry eggs and fry for about 21 days. Broods are smaller than those of most cichlids can be as large as 30 fry for mature females. The fry are large and can eat commercial food, Daphnia, brine shrimp nauplii, etc. immediately. The adults are not significant fry eaters, so the fry can be reared with the adults. The fry will, however, usually grow faster if removed from the adults. We maintain breeding colonies of this fish consisting of four males and twenty females.
