bettas originate in thailand (formerly known as siam). they can also be found in neighboring countries like laos, malaysia and vietnam. bettas were brought to japan and china after the fact. bettas are usually not fought to the death. while deaths can happen with overly aggressive fish, usually the loser will back off and the fight will be over. the fish are treated for injuries, winner is retired and bred, loser will be either let go or kept as a pet.AaronPenfound said:Well i think they have been given the nickname siamease fighters because in places like japan or china they stick two males in a tank an fight them to the death and people can put bets on which one will win! abit like cock fighting and all that sorta stuff!
