Hello everyone!

I just got my first Ball Python last night, I bought the 20g tank that they sell at pet smart from Zoo Med. I also bought a night light and a little thermostat with the humitidy reader.
My question is why is he moving so much, I don't think I have seen him in a ball. My roommate also got another bp but his is always in a ball and hiding.

oh and also he pooped in the glass last night I tried cleaning this morning but is really stuck in there... any ideas of how to clean the glass?

Thank you for help!
