The betta fish, also known as a Siamese fighting fish, is a species in the gourami family. They are native to the Mekong basin of Thailand, Laos, Cambodia and Vietnam. These fish are found in standing waters of canals, rice paddies and floodplains. They are called "pla-kad" (biting fish) in Thai and "trey krem" in Khmer.
Betta fish grow to a length of about 2.6 inches. Although domestic varieties come in vibrant colors, wild bettas are usually dull green, brown or grey. Male betta fish flare their gills, twist their bodies and spread their fins if interested in a female. Females darken in color and curve their bodies back and forth as a response. Males build a bubble nest for any potential eggs.
In the wild, betta fish consume primarily mosquito larvae and a small amount of vegetable matter. Despite the flashy fighting behavior between males that bettas are famous for, betta fish do not have flashy hunting behaviors because their prey does not run away. The diet of domestic betta fish includes live blood worms, brine shrimps and fish pellets.Learn more about Fish
