How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Check water parameters including pH, ammonia, nitrite, and nitrate levels.
Use a test kit to measure these parameters. Ensure the water quality is within the optimal range for Peacock Bass.
Recommended: Water test kit - Observe the fish for other signs of illness such as changes in color, appetite, or swimming behavior.
This can provide additional clues about the cause of the coughing or spitting.
- Consider the fish's diet and recent changes in the tank environment.
Ensure that the diet is appropriate and that there have been no recent changes that could stress the fish.
