Other names for this fish are: Japanese Fighting Fish, Samarai Fighting Fish, Chinese Fighting Fish and Mexican fighting Fish. The Cambodian Fighting Fish is a color range of this fish. If you set two males together they will customarily fight after going through a display. The show seems a part of the fish’s method of recognising the sex of the other fish. In a limited space like a small aquarium a fight would customarily end with one fish dead.
