About the species

Maylandia chrysomallos is a rock-dwelling mbuna of the blue-black zebra complex, endemic to the south-eastern arm of Lake Malawi where it grazes aufwuchs from boulders at the islands off Cape Maclear and on the Malawi–Mozambique border. Its name, from the Greek for 'golden fleece,' captures the warm gold sheen that overlays the light-blue, black-barred flanks of both sexes — a feature unusual among its zebra-group relatives. A maternal mouthbrooder and a typically pugnacious mbuna, it is one of the five rock-cichlid species named in the 1997 revision that split the old Pseudotropheus zebra into a genus of its own.
