African Idea's

German Ram?
not african, but.. size and temp range counts

Temporalis?
Two-Banded?

those two are Lake Tanganyika I believe, and are supposed to go to 80 degrees, 82 you'd be better with a south American variety


Agassiz's Dwarf Cichlid is south amazon. up 82 degrees

go up to species profiles and click through them all, would probably be faster than me listing the close ones!
