The Siamese fighting fish also known as the beta is a popular species of freshwater aquarium fish. The name of the genus is derived from akin beta 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 planeload in Thai or trey k rem in Khmer. They tend to be rather aggressive.B. resplendent usually grows to an overall length of about 7 centimeters including fins. Although known for their brilliant colors and large, flowing fins, the natural coloration of B. resplendent is a dull green, browns and gray, and the fins of wild specimens are relatively short. Brilliantly colored and longer-finned varieties have been developed through selective breeding.Properly kept and fed a correct diet Siamese fighting fish live about two to four years in captivity and up to 10 years in rare cases.The fish is a member of the gourmand family of order Performer but was formerly classified among the Anabaptist. Of the nearly 50 other members of the Berta genus B. resplendent is one of the most popular species among aquarium hobbyists.Berta species also prefer a warmer water climate than other tropical fish - around 25-30°C. They 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 the fish to be kept in maintained aquarium. This is a misconception as poor water quality makes all tropical fish including Berta resplendent more susceptible to diseases such as fin rot.
