The reason why small fish come to the surface of the water is mainly because the oxygen in the water body is insufficient, and the fish will float because of lack of oxygen. Once this happens, it needs to be oxygenated immediately, otherwise long-term hypoxia will lead to the death of fish. The method of oxygenation is very simple, as long as the water is properly changed, some oxygen can enter the cylinder, and oxygenation equipment can also be used for oxygenation.
1, too many fish: If the number of fish is too large, the fish need oxygen to breathe, so it is easy to cause it hypoxia. In view of this situation, we must control the number of aquaculture, fish out some fish, or prepare a fish tank, separate them for feeding, there will be no hypoxia.
2. The fish tank is too small: The dissolved oxygen in the water body is also related to the size of the fish tank. The bigger the fish tank is, the more water it contains. In this way, the situation of anoxia is less likely to occur. On the contrary, the fish tank is relatively small, little water will also lead to low dissolved oxygen, so it is easier to hypoxia, want to improve, as long as a large fish tank can be changed.
3. Overfeeding: Fish need to digest after eating, and this process is also continuous oxygen consumption, so feeding too much will also increase oxygen consumption, resulting in water hypoxia. This situation needs to reduce feeding, generally 1-2 times a day can be fed, too much feeding is also easy to bad water.
