Temperatures are fixed already.

He has been in the same tank for his entire life. This is the first issue. i am afraid that if I do take it down, the reduction in size will do the stressing. He is out every night and quite active in there.

I will move him to the spare bedroom for less traffic. I think us being in the room almost nightly may be contributing. I also keep the food in the same room as the snake. I have two 10 gallon tanks with rats in them that sit in the same room. Wondering if that is also a factor.

If the move and the heat does not fix it, I will reduce tank size.
