Aquarium Thermometers

A thermometer is an important piece to your complete aquatic set-up in order to help maintain the health of your fish. Thermometers may be external, sticking to the outside of the aquarium with an adhesive, or be submersible inside your aquarium. Placement of your thermometer will depend on the location of your aquarium's heater and should be on the opposite end of the tank from the heater, yet a location that is easy to check regularly. This will help you keep an eye on any temperature fluctuations that can be harmful to your fish.
