When breeding Thai betta fish, whether the fish can breathe normally is the key to their survival. In the case of large breeding density, it is necessary to add oxygen to the fish tank. If the total volume of all the fish in the fish tank does not exceed one tenth of the volume of the fish tank, the breeding density is not large, and the fish can grow normally depending on the dissolved oxygen in the water.
Once it exceeds one tenth, the breeding density will be relatively high. In this case, oxygen is needed. An oxygen pump may be use to oxygenate that water directly. Filtration devices can also be installed, which can also provide a certain amount of oxygen to the water. If the lack of oxygen is not too serious, it is enough to install only a filter device.
Thailand fighting fish is not necessary to always play oxygen. Even if the breeding density is large, it does not need 24 hours of uninterrupted oxygen supply. Because of the special gills of this fish, it can breathe air directly. When the dissolved oxygen in water is low, it can also get oxygen from the air as long as it rises to the surface. When the breeding density is high, because the area of the upper waters is limited, it can not guarantee that all the fish can breathe in the air, so oxygen is needed. However, it is not necessary to supply oxygen all the time, and excessive oxygen in the water will also bring disadvantages to the fish. It is suggested that the oxygen supply time should be controlled at 1 to 2 hours per day.
