When they were bred in Thailand for fighting, colour sorts were developed, but fins weren’t certain for in the modem sense. The long and fancy fins of the present fighting fish are a relatively recent development. Fighting fish are bred in lots of places. A lot of the fighting fish sold in Australia are bred in Singapore. Fighting fish are available in many colors adding blue, red, purple, white, yellow and black. Many various fin types have also been developed, adding the crown tail, the half moon the double tail and the delta tail.
