What's with the fish belly facing upstream? How to treat it?

There are many reasons why the fish's stomach is up, probably because the oxygen content in the water is relatively low, and the fish turns over due to lack of oxygen. It is also possible that the temperature difference of changing water is too large, which leads to the fish being stimulated and upset. In addition, if there is something wrong with the fish's swim bladder, resulting in the loss of the fish's swim bladder, it will also swim backwards. First, what happened to the fish's stomach facing upstream? There are many reasons why a fish's stomach is up. It may be because the oxygen content in the water is relatively low, and the fish turned over due to lack of oxygen. It is also possible that the temperature difference of changing water is too large, which leads to the fish being stimulated and upset. In addition, if there is something wrong with the fish's swim bladder, resulting in the loss of the fish's swim bladder, it will also swim backwards.

Second, how to treat 1, oxygenation: the loss of fish may be caused by hypoxia, and what needs to be done at this time is to increase oxygen in time. The best way to increase oxygen is to use oxygen pump, which is turned on 24 hours a day. If you feel that electricity is wasted, you can also switch it on and off regularly for at least 4 hours every day, which can also ensure the sufficient dissolved oxygen in the water.

2, temperature control: if the water temperature changes greatly, the fish will also appear belly up. This situation is stimulated to a certain extent, so you need to have a rest, and remember to keep the water temperature. If it is a tropical fish, the temperature should be controlled above 20℃, so as to ensure the health of the fish.

3, disease prevention: when the fish suffers from some diseases, it will also cause its stomach to face up. Generally, this disease is called loss of illness. This kind of disease should be prevented at ordinary times, so it is necessary to control feeding, do not feed food with too small particles, and change water regularly to ensure the water quality is clean and hygienic.
