How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Inspect the fish's body, fins, and mouth for cotton-like white or grey fungal growth.
Look for any fluffy, cottony material on the fish's body, fins, or mouth.
- Check the water parameters for ammonia, nitrite, and nitrate levels.

Recommended: Water test kit - Observe the fish's behavior and overall health.
Look for signs of stress or other health issues that may contribute to the fungal growth.
- Consider the recent changes in the tank environment or diet.
Identify any recent stressors or changes in the fish's diet that may have contributed to the condition.
- Examine the tank for other signs of disease or stress.
Check for any signs of other fish being affected or for debris that may indicate poor water quality.
How to Fix It
- Increase the frequency of water changes to maintain optimal water quality.
Change 20-30% of the water every other day until the issue resolves.
- Use an aquarium salt solution to treat the fish.
Dissolve 0.5% aquarium salt in the tank water and leave the fish in it for 5-7 days.
- Consider using an anti-fungal medication if the condition persists.
Follow the manufacturer's instructions for the dosage and duration of treatment.
- Ensure the tank temperature remains within the recommended range of 22–26°C.
Avoid sudden temperature changes that can stress the fish and worsen the condition.
- Remove any aggressive tankmates if necessary.
