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. This aquarium heater guide covers everything you need to know about heaters.

In the winter, the opposite problem can occur. This is especially true if your heater fails during this time of year, and steps must be taken to keep your fish warm.
