How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Perform a visual inspection of the fish
Check for any external signs of injury or parasites.
- Observe the fish's swimming and feeding behavior
Look for signs of discomfort or changes in normal behavior.
- Check water parameters
Use a pH test kit to ensure the pH is within the recommended range of 6.5–7.5.
Recommended: pH test kit - Examine the fish's diet
Ensure a balanced and appropriate diet is being provided.
- Consider the recent changes in the aquarium
Changes in water parameters, diet, or tank mates could be contributing factors.
How to Fix It
- Increase water flow and aeration
This can help with buoyancy issues and reduce stress.
- Perform a water change and maintain high water quality
Change 25-50% of the water to remove toxins and reduce ammonia levels.
- Consider using a probiotic in the water
This can help maintain a healthy gut flora and aid digestion.
- Remove any uneaten food from the tank
This can prevent overfeeding and the subsequent fermentation of food in the gut.
