Shallow rocky habitat, mainly between 0 and 4 m depth. Individuals are evenly
distributed throughout the habitat, each occupying a feeding area of roughly
2 m in diameter on rock surfaces covered with aufwuchs.
Geographic distribution:
Very restricted distribution. Endemic to Pombo Rocks and nearby Ndumbi Point
along the Tanzanian coast of Lake Malawi.
Typical adult size:
Males up to about 8 cm in the wild (up to ~10 cm in aquaria); females smaller,
up to about 6.5 cm.
Sexual dimorphism:
Minimal. Males and females share the same blue-and-black barred coloration.
Dominant males may show slightly more intense coloration.
Recommended aquarium size:
At least 300 L; larger aquaria strongly recommended due to intraspecific aggression.
Aquarium setup:
Dense rockwork with many hiding places. Strong water movement is beneficial.
Best kept in large groups (12 or more individuals) to distribute aggression.
Species-only aquaria are strongly recommended.
Diet:
Strictly herbivorous mbuna. Feeds primarily on algae scraped from aufwuchs.
Requires a diet rich in spirulina and other plant matter; high-protein foods
should be avoided due to risk of digestive disorders.
Breeding:
Maternal mouthbrooder. Spawning occurs without permanent territories in the wild.
Females incubate small broods (often fewer than 10 eggs) for about three weeks.
Aggression:
Highly aggressive in aquaria, especially toward conspecifics, despite relatively
peaceful behavior in the wild. Aggression is best managed by keeping large groups.
Special notes:
One of the smallest mbuna species. Extremely popular in the hobby but naturally
very range-restricted, which makes wild populations vulnerable despite extensive
captive breeding.
