This is but one of the many colour morphs of C.furcifer

I believe the one in the picture is C.furcifer "Magara" or "Kigoma", one of the most commonly found in the aquarium.

Above web site is a picture of Cyathopharynx foai "Karilani Copper".

These fish get to about 6inches.... and they're not some man-made hybrid fish. These are REAL cichlids found in lake Tanganyika.
