Siamese Fighting Fish (Betta splendens)
Male fighting fish are very territorial and have historically been used in gambling. Two male fish are pitted against each other in a fight and bets are placed on which one will win.
Despite their aggressiveness between males, fighting fish are not aggressive to other fish species. They can be successfully kept in community tanks, provided that fin nipping fish are avoided.
