Rocky habitat dominated by large boulders, usually free of sediment. The species is
rare in areas where rocks are scattered on sand or covered with sediment. Rocky
structures provide shelter and spawning sites.
Geographic distribution:
Known from Ngkuyo Island, Higga Reef, and the rocky shore south of Mbamba Bay known as
Chuwa, Lake Malawi, Tanzania.
Typical adult size:
Wild males up to about 14 cm total length, females approximately 2 cm smaller. In
aquaria individuals may reach close to 18 cm total length.
Sexual dimorphism:
Males and females differ clearly in coloration. Breeding males are blue to blue-white
with 7–9 distinct black lateral bars, blue anal fin, and lateral bars extending into
the dorsal fin without forming a dark submarginal band. Females are light brown or
occur as orange blotch morphs, with variable brown, yellow, or orange coloration and
irregular black blotches in OB females.
Recommended aquarium size:
At least 300 liters, with an aquarium length of 125 cm or more.
Aquarium setup:
Provide numerous caves and rocky shelters by piling rocks against the back of the tank.
Substrate choice is not critical, but sharp-edged materials are not recommended.
Only one male should be kept per aquarium.
Diet:
Primarily feeds on aufwuchs, combing loose material from the algal matrix, mainly
diatoms and short algal strands including cyanobacteria. It also feeds on plankton
and may form schools in the water column when plankton is abundant.
Breeding:
Males defend territories centered around caves among large rocks. Territories often
border one another and may be as close as one meter apart. Spawning occurs inside
the male’s cave. Females are maternal mouthbrooders and usually hide among rocks
while brooding.
Aggression:
Aggressive within the species, especially among males. Generally tolerant toward other
species of similar size and temperament.
Special notes:
This species closely resembles Maylandia zebra but has a noticeably more
slender body. It is sympatric with Maylandia fainzilberi throughout its range
and is not considered a geographic variant of that species. Detailed morphological
analyses have shown that it is also distinct from nearby zebra-like species such as
Maylandia midomo, Maylandia pambazuko, and Maylandia lundoense.
Orange blotch females are common and popular in the aquarium trade.
