I imagine you could keep a female Flowerhorn or a juvenile with African Cichlids. Like their Central American Amphilophine ancestors, Flowerhorns do best at pH 7 to 7.5. Adult males, however, are quite capable of killing anything of another species in the tank, and usually will. They do get 18 inches long and my foot long male can draw blood when he bites. Obviously, they think their territory actually extends as far as they can see outside the tank. The males are "Frankenstein" fish in every sense of the word: extraordinarily intelligent, strong, adaptable, and cruel. The much smaller females are about as bad as Jaguar or Cuban Cichlids, so can be in a very large tank with tankmates of an equal nature.
