An aquarium is another necessity that most people need if the keep tropical fish. An exception from this is if you keep your home very warm. If the room temperature in a room is kept at 74f or above then you do not need a heater. Some aquarium filters have built in heaters. If you buy one of these filters then you will not need a separate heater. Choose a heater that is designed for an aquarium of your size or larger. An undersized heater will have to work very hard to try to keep the temperature up and will be a lot more expensive to run than a larger heater. Make sure that the entire heater is placed under the water. You can read more about aquarium heaters here.
