  • LCD Stick-on Thermometers

The only time installation may be complicated will be if you already have the fish in the tank and do not have a separate tank to put them in while installing. Most of the best aquarium thermometers will have an easy-to-read display, however, not all of them come with this feature. If you get one that only reads by color then it may not be as easy.
