Digital Stick On Thermometer

It’s been about two weeks, and my 6 ottos are eating well and looking quite happy in their 30 gallon planted tank.

Simple and clean look to the tank. I personally try to put as little things as possible into the tanks, and I know the suction cups for glass thermometers almost always fail. This is a great solution. Granted, keep it away from vents or windows as the air temperature may affect the reading. Another thing is that it shows degrees in single digit increments as green. But if it falls between two, you won't see the green... you will see two blues. It took me a few days to get accustomed to that and to figure out how to read it. Seems to be consistent, plants haven't died yet... so that's a promising sign.

I like this product I can see the temperature easily when I am near the tank.
