So I have both and undertank Heater and a heat lamp. The temperature is right around 90, maybe a little hotter because the outside temperature is higher. Before he started burrowing he would hide all day and come out at night, but when he does burrow now (usually on the cool side by by the way) he gets under the screen that I use the separate the drainage layer and the substrate in the tank. I also am a little worried about that because I’m not 100% sure if he can find his way out. Like, he probably can but just in case I take him out from the ground at least once a day and set him on the surface to drink or whatever else. The only reasons I can think of that he would start doing this is because it has gotten a bit hotter and he is in shed and likes to be more hidden. If there’s anything else you can think of be sure to respond.
