Review on Aquarium Thermometer Accurate Temperature Amphibians by Cynthia Broederdorf

I have a betta in a 5 gallon aquarium. I already have a hanging thermometer, but I wanted to find something I could attach to the outside of the tank for easy and accurate temperature readings. It's perfect for that. You just stick it to the side of the tank (I stick it to the top edge, just below the waterline) and then press on the bottom where the 'on' symbol is to read the temp. The analog numbers are large and neon green, and the temperature is accurate to the decimal place. It mates with other thermometers (hanging and meat thermometers) so I know it's very accurate. Very easy to use and hygienic as there is no contact with aquarium water. I recommend to all fish owners, especially tropical fish that need stable warm water temperatures.
