  3. Check for signs of other diseases, such as scales sticking to the body or spots on the body.

  3. Isolate the affected fish to prevent the spread of the disease to other tank inhabitants.

    Use a separate hospital tank with the same water parameters.

  4. Maintain a consistent temperature and pH level in the tank.

  5. Feed a high-quality diet rich in vitamins and minerals to support immune function.
