Siamese fighting fish are endemic to the central plain of Thailand and have been domesticated for a minimum of 1,000 years, among the longest of any fish. They were firstly bred for aggression and field to playing suits corresponding to cockfighting. Bettas became known outside Thailand through King Rama III 1788 1851, who is asserted to have given some to Theodore Cantor, a Danish doctor, zoologist, and botanist. They first seemed in the West in the late 19th century, and within many years became common as ornamental fish. Their long historical past of selective breeding has produced a wide selection of colour and finnage, incomes them the moniker, “clothier fish of the aquatic world”. According to Witte and Schmidt 1992, Betta splendens is native to Southeast Asia, adding the northern Malay Peninsula, important and jap Thailand, Kampuchea Cambodia, and southern Vietnam.
