Betta fish (Betta splendens) are native to the shallow waters of Thailand, Cambodia, Laos, and Vietnam. They get their name from an ancient clan of warriors called the "Bettah." In the 19th century, Thai people bred them for fighting, similar to cockfighting, due to their territorial aggression. The King of Siam began taxing and licensing Betta fighting fish. In 1840, the King gave some specimens to a Danish physician, Theodore Cantor, who described them scientifically. They became popular aquarium fish in the West in the early 1900s and are now one of the most widely kept freshwater fish.
