Over and above that, can I use a fish tank thermometer to take my temperature?

A tool that is used to measure temperature. As you have probably guessed by now, an aquarium thermometer allows you to accurately check the temperature inside your tank. This small device is an essential piece of aquarium equipment – if you own a fish tank, then you need an aquarium thermometer. It's that simple!

Secondly, where should the thermometer be placed in a fish tank? The placement of the thermometer needs to be above the gravel line so it can get an accurate reading of the water. Floating and standing thermometers go inside the aquarium on the opposite side of the heater. A thermometer close to the heater might read higher than the actual temperature.

Next, how accurate are stick on aquarium thermometers?

Stick On Thermometer They aren't bad although they aren't the most accurate of options either. They sometimes can also be a bit difficult to read. Sticker thermometers work via a liquid crystal display that changes color with the temperature.

How do I know if my thermometer is accurate?

Add a little clean water until the glass is full and stir. Wait for about three minutes before inserting the sensor on the thermometer into the ice-filled water. Wait for about thirty seconds and check that the thermometer reads 32°F. If it does, then it is accurate, but if not, it requires calibration.
