- Observe the fish's behavior and overall health.
Note any other signs of illness or stress such as loss of appetite, aggression, or changes in swimming patterns.
- Check the water quality parameters.
Test for ammonia, nitrite, nitrate, pH, and temperature to ensure they are within the ideal range for G. aymonieri.
