Hi everyone I am new! So my bf and I got our very first Ball Python yesterday. He seems to be a male who I am assuming is 3-4 months old. We purchased him from Reptmart (I know they're not ideal).

Anyways he is very stressed. He is constantly climbing trying to escape. His UTH is regulated with Jumpstart and it's at 88 degrees I have it set to 90. He is cool side is at 80, and his humidity levels at 55.

I know one reason he is stressed is his tank is far too big for him right now. We were going to adopt an adult but it didn't end up working out. He is in a 40 gallon.
If I buy like another hide and some fake plants, and try to clutter up his enclosure do you think he will chill out a bit?

Also could it be I don't have enough substrate in the tank causing it to be too warm? I put enough to cover everything but it can be easily pushed to the side to expose the glass underneath. I use eco earth mixed with forest floor.

We tried to feed him yesterday, but he was too stressed to eat. So we're gonna put that off for a few days.
