I would recommend using an aquarium thermometer to check the starting temperature and that the heater is working correctly. The heater should have a thermostat which switches on and off to keep the temperature constant. You can leave your fish in the tank during this process if you can monitor with a thermometer.

It may be the pH change or other change in water chemistry. Use a home test kit to check water quality. Make adjustments as indicated. It may also be a response to a temperature change. Check water temperature and increase the heat if necessary, just don't forget to turn it down or off once the temp is within range.

The water temperature should range between 78F and 80F. You can use a submersible heater. Make sure it has an adjustable thermostat to control temperature. You should also have a thermometer in the tank to monitor water temp.
