Omigosh, everyone is overthinking this way too much.
If the temperatures are off by 5 degrees in the upward direction, that isn't the problem, really. It's a problem, but not THE problem.
In truth, Tobias is a 2 year old male snake, and it's the middle of winter.
He's also described as being very active.
He probably won't eat until spring.
Work out all of the husbandry kinks, sure, but as for food--offer him a smaller than usual prey item every 10 days, and don't stress when he doesn't take it.
He's more interested in girls right now than food. Assuming this is a healthy snake, and the enclosure is as described, then chances are pretty high that this is nothing more than a male snake that is off food for the breeding season. I have 3 mature males in my collection that are eating, right, now, the rest have been refusing since late November.
