Floating Aquarium Thermometer

Keep your tank’s water temperature on point and your aquatic friends comfortable with this simple, reliable floating thermometer. It features a dual-scale (°C and °F) display for easy reading and a built-in “safe zone” indicator — handy if you care about maintaining ideal conditions for tropical fish. The thermometer floats vertically for quick, obvious readings and also includes a suction cup for optional attachment to the side of your tank, so you never have to fish it out to check the temp. Compatible with both freshwater and saltwater aquariums, and requiring no batteries or complicated setup — ideal for everything from nano-tanks to larger systems.
