Why Use an Aquarium Thermometer?
Fish depend on suitable and stable water temperatures. A thermometer helps you notice temperature changes and confirm that your heater is maintaining the intended temperature.
For many tropical community aquariums, around 25°C is a useful general target, but the correct temperature depends on the fish species.
