Top one is a Metricalima Estherae and the 2nd one looks like an Estherae hybrid or poor breeding strain.
EDIT: Looking at your other post you have these 2 with corys and Tetra's (and Platies untill the Estherae killed them). If you want to keep your corys etc, move/return the 2 Mbuna, they are in no way community fish and should only be kept with similar species. Sorry but that is a disaster waiting to happen.
Agreed RED ZEBRA it is! strange though the top should be a female and the bottom should be a male but at the same time the bottom doesnt look like its it top condition??? give it time and he will look better im sure
