How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Examine the fish for signs of external injury or parasites.
Check for any lacerations, fin damage, or visible parasites.
- Inspect the fish's mouth and gills for any signs of disease or infection.
Look for any discoloration or excessive mucus.
- Measure the pH and ammonia levels in the tank water to check for toxic conditions.
High ammonia or pH levels can stress the fish and contribute to bloating.
