A Lake Malawi mbuna, yellow through the body with dark bars across it. Also called the hornet cichlid, and the scientific name means wasp, which tells you most of what you need to know about the look. Mature males often darken right down to a deep brown or nearly black, so a tank of them does not stay the same colour year round.

They are active, bold and territorial, so they want length to move in and plenty of rock and caves to break up the sight lines. Sandy bottom. Keep them with other robust mbuna and run one male to several females, which spreads the aggression around instead of letting it land on one fish. They will take flakes, pellets, algae wafers and meaty food like brine shrimp or bloodworms.
