The black shell shrimp is a kind of shrimp that consumes a lot of oxygen. But in the home, if the breeding density is not very large, then they can survive without oxygen. But if they are very dense, they may be hypoxic without oxygen, so it is better to give them oxygen. In addition, if there are aquatic plants in the tank, oxygen can not be used. Because aquatic plants can release oxygen through photosynthesis and increase the concentration of dissolved oxygen in water.
Whether the black-shell shrimp needs an oxygen pump can also be related to the breeding density and whether there are aquatic plants in the tank. If the breeding density is relatively low, or there are more aquatic plants in the tank, which can release enough oxygen, then it can be fed without oxygen pump. But if the breeding density is high. Then it is better to use an oxygen pump to give them oxygen. This prevents them from growing poorly due to lack of oxygen.
Generally speaking, the black shell shrimp does not need 24 hours of oxygen. They are more solid and can survive without 24 hours of oxygen. As long as the breeding density is not too high, oxygen can be used only when the water temperature is relatively high. If the breeding density is very high, oxygen can also be used for 24 hours, which is more beneficial to their growth.
