Pseudotropheus

Pseudotropheus is a genus of fish in the family Cichlidae endemic to Lake Malawi in Eastern Africa. Like some other large cichlid genera, such as Cichlasoma, a number of related fishes have been recently reassigned to different genera such as Tropheops or Maylandia. Some species of Melanochromis in turn have been moved into Pseudotropheus. Mbuna literally means "rockdweller" and this description accurately depicts the lifestyle of these cichlids which mostly live in rocky areas. Most pseudotrophine cichlids are algal grazers in the wild. Like most cichlids from Lake Malawi, fish from this genus reproduce via maternal mouthbrooding. The males often have egg spots on their anal fins which attract spawn-ready females towards them where they attempt to retrieve the imitation eggs while the male emits sperm into her biting mouth, thus fertilizing the eggs. The female and male generally move in an intensive circular motion while they spawn. Eventually, the female retrieves all of her eggs and incubates them in her mouth without eating for 2–4 weeks depending on the species and the particular fish after which the fry are released. Most, possibly all species of Pseudotropheus will breed together if given the right environment.
