I followed your tips, but he ended up dying the next day ): I guess he was sick or hadn't even eaten at the pet store in a while. I tried putting him in a separate tank with crickets in case he wasnt able to find them, but that didnt work either.

I plan to get another in the future but I'm waiting until my "reptile room" is finished so I don't stress the new one out too much with moving stuff around and whatnot. I bought a new tank as well so I'll be setting it up soon so it's ready.
