when i set him up and finally took a step back, i actually realized the food dish i was given with him was full of molded food; i couldn't tell until i picked it up and inspected it. idk how long it had been since he had fresh food.

he probably saw the fresh food and gorged himself.
i've read it's best to handle them frequently and regularly, and that the "grace period" before handling new reptiles doesn't really apply to these guys.
he's in my bathroom so he sees and hears me every day, and i make a point when i get home after work to check on him and talk to him and just observe him. i'm going to start handling every other day or so.
i'm going to keep him on paper towel until i get a better idea of when he poops and pees, so i know how often to check and clean. until i'm more comfortable with my knowledge of care for these guys, i'll keep the substrate as simple as i can. i'd love to go bioactive eventually.
that's a good point about not changing things in the enclosure for a bit, so they can pick where they want to be and get comfy.
pun intended?
thank you so much for all of your input and advice; it's nice to have someone to talk and learn with.
i can't wait to see my guy relaxed and jumping like Smeagol. i hope i can get him to trust me to jump to my hands!!!
