UPDATE:

-I'll post the pics next time I'm at my girlfriends.
-The tank is actually like 33 gallons or something? It's 3ftX1ftX1.5ft. I was told it was 50 but on second thought its probably a 30
-I wrapped insulation board around the tank. I also changed his hides to smaller ones since the other two where pretty big and I noticed he was always going into a paper roll tube I put in there.( can they get stuck in those?)
-The temp is like 80/92. But My thermometer on hot side, above the UTH and just a bit above the ground so I'm not sure if I'm suppose to factor in the UTH or something??? I'd love if someone could clarify that for me.

So, yea hopefully he will eat soon. I want to feed him live since he was fed live before but I don't want/can't keep a live rat if he won't eat it. So I will probably try frozen.
