On to day 2.
I am happy with my customized tub set up. He seems to have settled in nicely. Early this morning he was perched on top of the wood branch and he is currently in his hide. I hope that is because he is comfortably regulating his temperature. Thank you to El-Ziggy for the specifics on the tub and Gio for his permanent enclosure.
Last night when the kids and my wife got home we found him squeezed into the top wall of the tub like a rock climber. Pretty cool. I did have to open the enclosure for the kids, not what I wanted to do, as I want him to rest for the week. But, I gave them one chance as they were so curious.
Side note, he is a quick mover! My only personal experience with something similar would be a southern black racer that we find outside here occasionally. Similar size and speed. Definitely not going to set him down next to me on a chair like I do the BPs!
