Sorry, I'm pretty sure I said this but he already has a thermostat and it works just fine! I got him a bigger tank since he is a bit bigger than a baby. Not too much, but enough that a ten gallon just seemed way too small for him. He seems to like it. He seems to like climbing a lot so I got him some climbing decorations that double as hides. He seems to love them. He also has a new cave shaped hide on the cooler side of his tank which he loves. I also added some fake plants. He's not climbing and pushing on the top of his tank anymore, he just seems to be climbing and resting on his climbing trees, so I think he just wanted a little more space. I also got an actual reptile tank instead of a normal one. This one has a sliding lid, so I'm not worried about him escaping anymore
Thanks guys for all your help! And I would imagine he is a little stressed, but that's due to the fact that i JUST got him two days ago. I'm just being a worry wart. Though, he ate perfectly fine today and seems content with the new tank. So for now, I think I figured it out. Thank you all so much for your help!!
