Dave has them, they are Fainzilberi.
Tropheop species are also a nice looking group that are supposed to be pretty aggressive. You dont see them in alot of tanks.
IMO, only one Zebra Chilumba per tank. The one I keep dominates the entire 120 gal. tank, which includes Red & Blue Zebras, Kenyi, Socolofi as well as various predator Haps & Peacocks. One is all you need, very awsome Mbuna.

These guys are very interesting as not only the males are good looking but the females are a bright attractive yellow instead of dark and drab. Trying to track down some but not having any luck. Have any idea where I might find some??
