How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Inspect the fish for any visible signs of injury or disease.
Look for wounds, lumps, or signs of parasites.
- Check the water parameters for ammonia, nitrite, nitrate, pH, and temperature.
Use a water test kit to measure these values.
Recommended: Water test kit - Observe the fish's diet and feeding habits.
Ensure it's being fed a balanced diet and not overfed.
- Check the tank environment for stressors like aggressive tankmates or inadequate space.
Ensure the tank is well-maintained and stress-free.

How to Fix It
- Improve water quality by reducing ammonia and nitrite levels and maintaining optimal pH and temperature.
Perform water changes and use dechlorinators if necessary.
- Adjust the diet by feeding high-quality, appropriately sized food and reducing portion sizes if overfeeding is suspected.
Monitor the fish's weight and health closely.
- Remove any aggressive tankmates or provide adequate space if tank size is an issue.
