Thanks all.. Xan they are considered dwarf Mbuna species, Afra Nkhata there average size is 4" sometimes 5" as adults, these guys are just under 2" they are a typical mouth brooder so a slight bulge in the throat area will def incline that a female is holding eggs, as the eggs hatch and when the fry are growing the bulge will def expand, 6 photos down of my fish above you will notice the female holding eggs..
