siamese fighting fish temperatureBreathingFighting fish are anabantids. They and their household can breathe air as well as water. This means that they could live in much smaller aquariums than most fish. In the wild they on occasion live or even breed in very small bodies of water adding the water filled hoof prints of a water buffalo. They are sometimes also found in rice fields. They are looking to be in a position to get to the surface or they could drown.
