Yes - sorry, I've confused the words "thermostat" and "thermometer" since I was little, lol

Thank you! I've been dealing with some misinformation since I got him ("experts" at my local pet store who've told me that as long as humidity is above 55%, it can be up to 90% and be fine).

I'll look for some substrate, as well as a new hide. I'll also try to find some new fake plants (they're so unreasonably expensive!), and will move the water bowl for sure. Thank you so much! I'm going to try to post some updates to a new thread once I get on top of this more.
