Thank you guys for letting me know this is normal. I totally agree with Zincubus, I don't think he was fully relaxed yet. He always balled as deep into his log hide as he could, pressed against the glass. I noticed yesterday that he is now comfortably in the middle of the log and actually peaks out more. I had to do some adjustments to his tank and the whole time he didn't hiss (and he's a hissy baby) and actually poked his head out a bit to see what I was doing. I have a thermostat now! His hot side was wwaaayyyy too hot, but everything is perfect now. But it used to be I'd open his tank and he'd tense up and squish himself deep into his log. I feel bad that I may have caused a bit more stress unintentionally. But he seems to have settled in now and I'm super happy about it.
