space will be a problem my friend...these fishes will get really big. an eight to ten year old speciment will not share its tank with any similar size fish. they are loners once they reach adulthood. actually i dont grade frontosa by numbers i.e ...f1 or fo but by their name to avoid confusion and cheating by the LFS. kapampa,zaire and burundi being the more common ones ...i really like the kasanga ,bulu point and especially the kigoma(man, i cant afford this one). well, keep your fish , dont trade it...after all its no easy to sell or trade with LFS...unless they could make something out of it
