Psuedotropheus Acei is one of the most popular of Mbuna because as well as being beautiful to look at, they are widely compatible with many species. Although their shape is different to many Mbuna of the Psuedotropheus genus(they look a little like G. moori), they share the same shaped outer jaw teeth. Acei are great to keep and you will rarely see them cause problems within the social makeup of your tank.
