It will take a while to figure out the quirks in your ball's personality...but usually, a healthy and stress-free ball python will hide all day and then come out at night to explore. As I like to put it, a hiding ball python is a happy ball python! Roaming too much around the enclosure could be a sign of stress.

When your ball slithers around while out of her enclosure and flicks her tongue regularly, she's just being inquisitive. Unless she is thrashing and obviously trying to flee when she's out, you shouldn't worry. (:

Keep in mind that ball pythons don't particularly enjoy being handled frequently, and too much of it could cause some discomfort. Some can tolerate being held more than others. You'll just need to spend some time studying her to figure out how much handling is best for her.

Just give it a while and you'll figure her out. Best of luck, and cheers!
