A Powerful and Beautiful Mbuna
Pseudotropheus sp. "black dorsal" (possibly Metriaclima phaeos) from Lundo Island is a stunning fish once fully colored. As an aquarist, you quickly witness how the male can transform from an inconspicuous fish into a brilliant blue ruler of the tank. However, it is a species that demands space and an owner prepared for its temperament.
Behavior and Dominance
This species is known for being quite aggressive and dominant. The male does not hesitate to chase both females and other species in the tank to assert his territory. In smaller setups, this can cause significant unrest and restrict the movement of more peaceful mbunas, which is a crucial consideration when planning tank mates.
Breeding: From Digging to Fry
Breeding this mouthbrooder is a fascinating process. Leading up to spawning, the male becomes very active, digging pits in the sand where the actual mating takes place. After spawning, the female carries the eggs in her mouth for just over three weeks. Experience shows that the female can release broods of over 30 fry if moved to quieter quarters toward the end of the brooding period.
Identification and Habitat
There is often uncertainty regarding the correct scientific name; while frequently sold as Pseudotropheus, experts like Konings believe it belongs to the Metriaclima genus. In the wild, it is found along the coasts of Lake Malawi, living in close association with rock formations.
