Betta raja is a species of betta endemic to the island of Sumatra in Indonesia. It is an inhabitant of swamps in lowland forests. This species grows to a length of 6.4 centimetres (2.5 in) SL. It is used as bait by local fishermen and has also been found in the aquarium trade.[2] Despite its scientific epithet "raja" meaning "Prince" or "king", this species is not identical to the aquarium breed - the King betta. The derivation of the King betta is not fully known and may or may not involve crossbreeding with B. raja.[3][unreliable source?]
