The reason why the goldfish's belly is upward but not dead may be due to the following three reasons: 1. Caused by swim bladder disease, which may be caused by the fish suffering from swim bladder disease, which leads to this phenomenon; 2. Caused by lack of oxygen, which may be caused by the goldfish's lack of oxygen. Oxygen may not adapt to the water quality, resulting in the phenomenon of belly turning; 3. Caused by eating too much, it may be that the owner feeds too much, causing this phenomenon in goldfish.

Tip:

When this phenomenon occurs in goldfish, the owner should immediately change the water of the goldfish, and then sprinkle an appropriate amount of coarse salt in the water for disinfection and sterilization. During this period, attention should be paid to stopping feeding. If the situation is not very serious, the goldfish will be able to recover in a few days. It gets better, but if it is more serious, then medication is needed for treatment.
