The Siamese fighting fish is also referred to as The Betta. This species was widely kept in Thailand for more than 200 years before it became known in the West in the late 1800s.
Different strains evolved from cross breeding fish obtained from various parts of Thailand. As a result, it is now practically impossible to be certain of the original distribution of this fish, or their natural colouration.
Since its introduction breeders have concentrated on establishing a whole wide range of colour forms, ranging from white through yellow to purple. Selective breeding has also been used to modify the fins, which are always more elaborate in case of Male Bettas.
