AQUARIUM CARE: Probably the least aggressive Melanochromis (certainly when compared to M. auratus and M. chipokae), though still quite boisterous like all mbunas. Best kept in a group, one male to several females. Sexing is simple as males are black with light blue patterning, whilst females (and juveniles) are generally yellow (see pictures). Like all mbunas it will graze on algae and plant matter, and should be fed foods with some vegetable component.

Best kept in a well-stocked mixed mbuna tank, or in a larger species group, preferably with two to three times the number of females than males. Tank décor should be rocky, with caves and passageways. Plants will usually be disturbed (with the exception of Anubias, java fern and perhaps Vallisneria.

BREEDING: A typical maternal mouthbrooder

Fishkeeping Facts and Tips

Give your fish a treat! Flaked fish foods are excellent nutritionally, but most fish really enjoy tucking into live, or frozen live foods. Insect larvae such as bloodworms can be collected in summertime from your water barrel, but it is also very worthwhile to attempt to culture Daphnia or white worms for a free food source absolutely relished by aquarium fish. Frozen bloodworm are almost as good and are widely available, though freeze dried live foods tend not to go down as well. See more on feeding fish
