The luhan fish is a kind of highly oxygen-consuming fish. It consumes a lot of oxygen for breathing. The dissolved oxygen in the water alone can not make it breathe normally. Moreover, the excretion of Arhat fish is large, and the deterioration of water quality is easy to cause hypoxia. Therefore, in the process of feeding, it is necessary to add oxygen to the water. The water body can be oxygenated by means of an oxygen pump or a filter. If the fish breathes rapidly or floats its head out of the water, it indicates that the dissolved oxygen in the water is very low, and the oxygen supply should be increased, otherwise it will affect the metabolism and breathing of the fish. Generally speaking, as long as the oxygen content of the water body in which it is raised is 5 to 7 mg/L, it is enough.
The ambient temperature where the Siraitia grosvenorii live is 28 ~ 30 ℃. Under high temperature, oxygen in water loses quickly. And it is a large fish with high oxygen consumption. In order to ensure its normal life, it needs 24 hours of uninterrupted oxygen. Sufficient oxygen can make its condition better and its color more brilliant. If the fish tank is equipped with a filter, you can not always use oxygen. Because the filter has an aeration device, it can also deliver oxygen to the water. However, the filter provides less oxygen, usually need to open the oxygen pump for 1 to 2 hours.
