How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Measure water parameters for ammonia, nitrite, nitrate, pH, and temperature.
Use a water test kit to check these parameters.
Recommended: Water test kit - Check the tank for signs of aggression or stress.
Observe tankmates and the tank environment for any potential stressors.
- Inspect the fish for signs of external parasites or internal bloating.
Look for any spots or lesions on the body.
- Monitor the fish's diet and recent changes.
Consider any new foods or feeding schedule adjustments.
- Review the tank maintenance schedule.
Ensure regular water changes and tank cleaning are being performed.
How to Fix It
- Increase aeration or add an air stone to the tank to improve oxygen levels.
This can be done by using an air pump or an air stone.
- Perform a partial water change (25-30%) to remove toxins and improve water quality.
Use dechlorinated water for the change.
- If aggression is detected, rearrange the tank or provide hiding spots.
This can help reduce stress and aggressive behavior.
- Adjust the diet to include easily digestible foods and reduce the feeding frequency if necessary.
Avoid overfeeding and ensure the food is suitable for the fish's digestive system.
