The solution to the white spots on fish tails is as follows:

1. Raise the water temperature of the water tank to 25-28 degrees, and then change the water. When changing the water, the temperature difference should not be too large, and should not exceed 1 degree.

2. You can also add some coarse salt for disinfection and sterilization.

3. If the fish's illness is serious, treatment drugs will need to be used, and it will recover in a few days.

Tip:

White spots on fish tails are caused by fish suffering from white spot disease, which is usually caused by low water temperature or poor water quality. White spot disease is caused by the infection of small melon worms in the water. When the water temperature is low, the small melon worms will multiply and infect fish. Therefore, the most effective method of treatment is to increase the water temperature to kill the small melon worms.
