The Siamese fighting fish (Betta splendens, ) also known as betta, 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, Laos, Cambodia and Vietnam and are called pla-kad (lit. biting fish) in Thai or trey krem in Khmer.The fish is a member of the gourami family (family Osphronemidae) of order Perciformes, but was formerly classified among the Anabantidae. Although there are nearly 50 other members of the Betta genus, B. splendens is one of the most popular species among aquarium hobbyists.Betta Species also prefer a warmer water climate than other tropical fish - around 25-30 Degrees Celsius.(77-86 Degrees Fahrenheit) Betta fish have an organ known as the labyrinth organ which allows them to breathe air at the water's surface. It is often wrongly thought that this organ allows Betta fish to be kept in unmaintained aquaria.This is a misconception as poor water quality makes all tropical fish, including Betta splendens more susceptible to diseases such as fin rot.
