One of the most common problems for new aquarium owners is understanding why they need a heater for their tank. Don’t make the mistake that so many others do and go without one! A heater can be critical to the health and longevity of your pet fish. Why do you need an aquarium fish tank heater? Most aquarium fish come from warm waters and need to be above room temperature. Typically, those colorful little fish you got at the pet store are found in the Caribbean, the South Pacific and other warm waters. If they are used to warmer water, they’ll need the same thing in your home aquarium. People sometimes wonder why a healthy looking fish suddenly died and sometimes, temperature is the issue.

Aquarium heaters are inexpensive and keep temperatures stable no matter what it's like outside. Did you know that fish don’t produce their own body heat? Its true. So, you’ll need to produce it for them. Fish also don’t enjoy changing temperatures and water conditions. These little guys are sensitive creatures!

Pet Mountain has two types of fish tank heaters: fully submersible heaters, and heaters that go in your canister filter, power filter or sump. Either will get the job done, so make your decision based on what you like and what you can afford. Be sure that you have a working thermometer as well.
