Additional names

Additional scientific names

Pseudotropheus johannii


Endemic to Lake Malawi.


Males are blue whereas juveniles and females are yellow.

Tank compatibility

Should be kept in an African Cichlid Mbuna set up only. Several females should be kept per male.


Will accept most foods including cichlid pellets, live/frozen food such as bloodworm and brine shrimp and will also nibble at plant matter. Common diseases are Malawi Bloat from too much protein. Mbuna are mostly herbivores, do not feed them like South American Cichlids, something low protein like New Life Balance is good. Emerald Entree is a good low protein frozen food. They love fresh vegetables, weigh them down with something and they'll figure it out eventually.

Feeding regime

Feed once or twice a day. more often when they're younger so they reach maximum size

Environment Specifics

Prefers a typical Mbuna type set up of a high pH and rockwork decor. At least 2 caves per cichlid.


Territorial and aggressive, a typical African Cichlid.


Elongated vibrantly coloured fish. Males are brilliant sky blue to dark blue, the colours show a "checkerboard" pattern with alternating light and dark patches, with several light-coloured "egg spots" on their anal fin. Females and juveniles bright yellow-orange in colour. Can be mistaken for Melanochromis cyaneorhabdos.
