Sounds accurate to me, the first one I think we might need a better pic of the face though, last one looks like a pseudotropheus of some kind, may be pure or not I don't really know. either way hes the only Mbuna
Agreed on the Buccochromis as neither of the Champsochromis have yellow in their fins that I can recall.The fish in the third photo looks like some kind of Lake Victorian cichlid.
Thanks everyone. Another forum I posted to thinks.
1. Buccochromis species
2. Placidochromis electra "Deep Water Hap"
3. Astatotilapia latifasciata "Zebra Obliquidens".
4. One of the Elongatus with a yellow tail.
