Betta splendens   Regan, 1910
Siamese Fighting Fish aka Betta

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, Cambodia and Vietnam and are called pla-kad (lit. &quot;biting fish&quot;) in Thai or trey krem in Khmer.

B. splendens usually grow to an overall length of about 3 inches, including fins. Although known for their brilliant colors and large, flowing fins, the natural coloration of B. splendens is a dull green and brown, and the fins of wild specimens are relatively short. Brilliantly colored and longer finned varieties (i.e. Veiltail; Delta; Superdelta; and Halfmoon) have been developed through selective breeding.
