Use a reliable test kit to measure these parameters.
Recommended: Water test kit - Monitor the tank's temperature and ensure it is within the optimal range of 22.0–28.0°C.
Use a reliable thermometer to measure the temperature.
Recommended: Thermometer - Inspect the fish for signs of infection, such as ulcers or spots.
