Distribution
Labyrinth fishes are only found in southern and western Africa and eastern and southeastern Asia. Figure (1) represents the natural range of these fishes. The natural distribution of Labyrinth fishes has a northern boundary in China at latitude 50 degrees. The eastern boundary of natural distribution is in Korea at a longitude of 130 degrees. The southern most ranges are in Sumatra south to the equator with the western limits in India to longitude 70 degrees east. Trichogaster Trichopterus occurs naturally in southern Vietnam, the Suda Islands, Thailand and the Malayan Peninsula (Richter 1988).
