Maintain stable temperatures of your aquarium with an aquarium heater.
The temperature of your aquarium is an important factor in the comfort and well-being of your fish. Unlike humans and other mammals, fish do not produce their own body heat. They must rely on the temperature of the water to maintain their body temperature. This makes it very important that you keep your aquarium at the proper temperature for your pets.
