Coughing or spitting in Croaking Gouramis can indicate respiratory issues, often due to poor water quality or stress. This problem is usually not life-threatening but requires prompt attention. Owners should first ensure the tank conditions are optimal and consider the fish's diet and recent environmental changes.
Common Causes of Coughing or Spitting in Croaking Gourami

How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Check the water parameters for ammonia, nitrite, and nitrate levels.
Use a test kit to ensure the water quality is within the ideal range for Trichopsis vittata.
Recommended: Water test kit - Observe the fish's behavior and appearance for other signs of illness.
Look for signs of infection or other health issues, such as bloating, fin rot, or cloudy eyes.
- Inspect the tank for any signs of aggression or overcrowding.
Ensure the tank size is appropriate for the number of fish and that there are no territorial disputes.
- Review the fish's diet and recent changes in feeding.
Ensure the diet is balanced and appropriate for the Croaking Gourami's nutritional needs.
- Consider any recent changes in the tank environment.
Changes such as new decorations, plants, or fish can stress the fish and cause coughing or spitting.
How to Fix It
- Improve water quality by performing regular water changes and maintaining optimal ammonia, nitrite, and nitrate levels.
Change 20-30% of the water weekly to maintain a healthy environment.
- Remove any aggressive tankmates or overcrowding issues.
Ensure the tank provides enough space and that all fish are compatible with each other.
- Adjust the diet to ensure it is balanced and meets the nutritional needs of the Croaking Gourami.
