unknown Pseudotropheus

These are 3 African cichlids from Lake Malawi, whose specific scientific classification is still a mystery to me (possibly a Pseudotropheus). They were purchased at a local aquarium shop and have nice coloration, similar to some Tropheus Moorii. This is one of many fish varieties found in the rift lakes of Africa and referred to as 'mbuna' (meaning rock dweller) by indigenous people.
