I am new to snakes and rescued a ball off from craigslist. I've had him a month and I am REALLY excited to work with him(her?) and hope to collect more in the future, I am hooked for sure! With that being said, read below.

History: I've had my snake for a month. He took a live mouse the first time we fed him (48hrs of him being "home"). He's had one shed and eaten 2-3 mice at a time each week. He seems incredibly healthy and I don't care what anybody says, he likes being handled. If my wife or I have him out and set him on our bed he immediately climbs back onto our arms and seems quite content to hang out on our shoulder (straight neck, no hissing and I almost have to wrestle him into his tank). The tank is where I have my issue. It is a 20gallon long tank with aspen and an UTH under his rock hide (bought it at PetSmart and he seems to love it). I have a thermostat with a probe under his hide and typically kept it at 82-85 degrees. I noticed the cage would drop to 75-80 ambient even with a towel over the top. I figured I should turn up his UTH to raise the temps, we have a heat lamp but only want to use it when we NEED to use it.

Issue/Question: I wanted to turn up the UTH but I didn't want him to be uncomfortable. I purchased an identical hide last night. I went so far as to inspect the inside to make sure the texture was the same. I have an UTH under the one and the other is just ambient. When I got home from work a few minutes ago I noticed the UTH had his warm hide at 91.7 and I am concerned as my wife said it was that temp all day. Should he have moved from there to his other hide? Is it too warm? Am I just worrying because I am new to this? Below is the picture of his home, his warm side is on the right.

Tonight we'll be getting some of that spray on window frosting and covering 3/4 of the glass panels to keep him happier. Sometimes he gets jumpy if I change web pages at night as the screen is just to the right in the picture.
