Bettas

Fish - Fresh Water

The Siamese fighting fish, also known as the betta (particularly in the US), is a popular species of freshwater aquarium fish. The name of the genus is derived from ikan bettah, taken from a local dialect of Malay. The wild ancestors of this fish are native to the rice paddies of Thailand, Malaysia and Cambodia and are called pla-kad in Thai or trey krem in Khmer.
