Recommended: Water test kit - Inspect the tank for any signs of poor hygiene or overcrowding.
Ensure that the tank is well-maintained and that there is enough space for the fish to swim and avoid aggression.
- Review the fish's diet and ensure it is balanced and nutritious.
Provide a varied diet that includes high-quality flake food, freeze-dried, and live foods to support the fish's immune system.
- Consider if any new additions to the tank may have introduced the fungus.
If new fish, plants, or decorations were recently added, ensure they were properly cleaned and quarantined before introducing them to the main tank.
How to Fix It

Change 25-30% of the tank water weekly to remove harmful substances and maintain a healthy environment.
- Use an anti-fungal treatment as directed by a veterinarian.
Follow the instructions carefully to ensure the correct dosage and duration of treatment.
- Isolate the affected fish to prevent the spread of the infection to other tank mates.
Keep the fish in a separate tank with similar water parameters and continue treatment until the infection is cleared.
- Remove any uneaten food and debris from the tank to prevent the growth of harmful bacteria and fungi.
Regularly clean the tank and remove any waste that accumulates.
- Monitor the fish's response to treatment and adjust the care routine as needed.
