    This Cichlid is a very colorful, active fish from Lake Malawi in Africa. The coloring of both the male and female is very appealing, and they almost look like two separate species. The male has a brilliant blue body with darker blue striping, but the dark colors "bleed" onto the lighter blue creating a checkerboard effect. The female and juveniles are a bright yellow-orange.
   This cichlid belongs to a group called Mbuna cichlids. This group has 13 genera of very active and aggressive personalities of Mbuna cichlids. The name Mbuna comes from the Tonga people of Malawi and means "rockfish" or "rock-dwelling". This name aptly describes the rocky environment these fish live in as opposed to being open water swimmers like the Utaka cichlids and other "haps" . Some other common names this fish is known by are Johanni Cichlid, Blue Johanni, Bluegray Mbuna, and Blue Mbuna.
    The Blue Johanni are very attractive African cichlids, and having opposite coloring makes keeping both sexes in the aquarium desirable. Though still not a community tank specimen with fish other than cichlids, they are some of the least aggressive of the Melanochromis species. They are very easy to breed and the juveniles are very easy to raise as well.
A large aquarium with plenty of caves and hiding places is ideal for these fish. An aragonite-based substrate is recommended in order to maintain the necessary high pH and alkalinity.
    The males should be kept with at least three females. The female will spawn on a flat rock, and will take the unfertilized eggs into her mouth and will follow closely behind the male until he releases the sperm to fertilize the eggs. The female will then incubate the eggs for approximately three weeks before releasing the fry. The fry can then be fed newly hatched brine shrimp, daphnia, or crushed flake food.
     The Blue Johanni can be fed with some of vegetable rich foods in the form of flake food, dried seaweed and algae.
