I know everyones probably going to yell at me here, but I dont have a thermostat on any of my Zoo Med UTH heaters. So I was just wondering how hot is too hot? If it was too hot for them, wouldnt they just move over to the cool side? I have shelf liner as my "substrate" in 4 aquariums, and sand in another (I know its controversial, and I am careful with feeding). So if there is something sheilding them from the hot glass, how can they get burned? Is 110 too hot for inside the hot hide?
