- Perform a physical examination of the fish, including the gills, scales, and fins.
Check for any external signs of disease such as spots, ulcers, or fin rot.
- Take a water sample to check for ammonia, nitrite, and nitrate levels.
Poor water quality can contribute to stress and weaken the fish's immune system.
