Yep the heating pad is on the side! I do mist the tank regularly and I even have some plastic wrap loosely on top of the lid to trap moisture and slow down evaporation. I haven't changed the substrate in a while, maybe 2 months. I usually don't wait that long but since he hasn't been eating he hasn't really produced much waste to dirty it up and breed too much bacteria I would think. I did just get some new soil though and I'm strongly considering doing a change within the week. He doesn't have any artificial lighting right now. He used to for a brief period when I got him but then based on my research apparently they don't really need it and an overhead light can actually hurt their eyes. So I read at the time. However I'm in the room often and I'm always flipping on the light and there's a big window in the room for some natural sunlight plus the residual light from my bearded dragon and garter snake tanks across the room. And yes for sure I'm going to give him the pedialyte bath now and I think a little honey is a nice touch!
