Solutions to the fish's eyes that become enlarged and protruded:

1. Change the water: After the fish's eyes become enlarged and protruded, the water must be changed in time, and the speed of water change cannot be too fast.

2. Heating: Increase the water temperature appropriately. The purpose of raising the temperature is to speed up metabolism, which can rejuvenate the fish. It should be noted that the temperature cannot be raised too high at one time.

3. Add salt: Add a little salt after the temperature rises. This can increase the osmotic pressure of the water and reduce the invasion of bacteria. The concentration of salt is usually 3 to 5 thousandths.

4. Add yellow powder: If the problem is not relieved, stop changing the water first and add yellow powder in the water. After the fish improves, change the water and add salt.
