I have a gauge in his tank right now as well as a probe thermometer and an infrared digital that I use to check the temps daily. Thanks everyone!!!

Iv I’ve heard of a thermostat and rheostat for lamps, but I didn’t know they had them for UTH. That, I definitely will be getting tomorrow. I’m looking for a larger tank for him, but I wanted to see how he would do 1. In a new home, 2. In an environment bigger than the small 12” x 4” tub he arrived in.
