The floor temp is actually cooler than the ambient because I have the tank raised above the uth right now. I haven't been able to get a reptile uth and thermostat yet, but I'm working on it.
I soaked him on Thursday because ALL of his shed was stuck. (he's had bad sheds his entire life since he's never been taken care of correctly). He wouldn't let me touch his head or neck so I'm going to try again tomorrow, just didn't want to stress him out more than the bath already had.
His hide seems like a good size to me. When he curls up in it the sides touch him pretty snug. But he definitely has room to grow into it still.
