The white floc on the parrot fish is usually caused by the water. In this case, we first need to adjust the water quality and temperature, and then use some antibiotics for antibacterial and anti-inflammation. Generally, it can be improved. When raising parrot fish, you should pay attention to ensuring that the water quality is clean and hygienic, and the water temperature should be appropriate.

Tips:

When we change the water for fish, we must ensure that the temperature difference between the new water and the old water is not large, the water quality must be clean, and the pH must be appropriate.
