He's usually pretty chill about changes to the tank, after sniffing around he went back to his hide (right after the change). Woke up this morning and he is in his hide again. I think he was still coming down from the stress of being bagged fast Saturday and having a bunch of strangers' scents in the house. plus the temperature thing. Haven't checked the temps this morning yet, but the couple of times I did yesterday and last night it seemed like my temporary fix has them adjusted. Though I'm still gonna switch out the UTH heating system to a new one on Thursday so I can run a couple of tests on the old one to make sure it didn't malfunction for my peace of mind.
