Ball Python Behavior?

[Cina]

Hello, I just got my first ball python about three weeks ago. At first, I had him in a tub, but the humidity became too high. (I wasnt expecting my house's humidity to be 42%). So, I switched him over to a glass aquarium. In both the tub and tank he does what I pictured below. He slides his belly up against the glass and keeps doing it for about a half an hour to an hour at a time. He'll fall over and do it again. His warm side of the tank has an under tank heating mat. The probe directly under the heating mat reads 92 farenheit. The one that I use to check the tank usually reads about 87 to 88 farenheit under a little bit of substrate. His cool side is a steady 76 farenheit. His humidity in the tank usually goes from about 60% to 77%. I tried putting a towel over the top and sides, thinking maybe the glass was confusing/stressing him out, but he still does it. The tub was 30 gallons and the tank is 29, so theres not much of a difference. He tolerates handling very well. And hes on a regular feeding schedule every Monday and thursday and never has a problem eating. (Hes almost 2 months old, but only 91 grams. The breeder I got him from was only feeding him every 8 to 10 days, and most places said that 91 grams is a little underweight for a 2 month old ball python). I havent seen anyone talk about ball pythons being this active. Not to mention when I first got him, he spent a lot of time in his hide. Now hes constantly roaming around and climbing. He also seems to like to lay on top of the vines on the cool side of his tank or on top of his climbing pole on the warm side. I'm just wondering if this is normal? Is he trying to get out? Is he not comfortable? Is there something I'm doing wrong? I've been looking everywhere, but I cant seem to find anyone else who has an extremely active, (maybe curious?) ball python like mine. Or one that enjoys being out in the open, closer to the top of the cage rather than the ground, instead of in their hide. I attached pictures of his behavior and his tank setup (minus the towel obviously) to see if anyone has any suggestions or sees any problems? Just for note, his water dish is just big enough for him to soak in, I do use reptisafe for his water and eco earth for his substrate. I just want my ball python to be as happy and healthy as possible. Thank you!

He has also never balled up on me or anyone else in the house, nor has he ever bitten. I know that all of those are signs of stress, but he doesn't show those behaviors, so I'm not sure if he's stressed or not.

What size mouse are you feeding him, and what weight is the mouse? How often do you feed him?
What are the dimensions of your tank in inches?

We had our juvenile doing the same thing when we first got him. (We got him when he was around 2 months.)
At this point, I wouldn't move him again. Your humidity sounds OK, but try to keep it in the 50s and 60s.
For temperature, I recommend getting an infrared heat gun at your local reptile store and using that to verify temperatures.

Once you have verified that the husbandry is correct, start looking at your hides. We have somewhat of a similar set up to you. We have the same tree on our cold side, and a half log on our hot side. In the center, we have a humidity hide. This is not ideal for hides, as you want the same hide on the hot and the cold side so the snake doesnt have to sacrifice security for thermoregulation. For us, our humidity hide temps as a cool hide, and seeing as he has had a lot of change in his environment recently, we are waiting to upgrade his hides until a few sheds from now. Half logs are not good. You don't seem to have any suitable hides at all. This could be the reason why he is stressed out. I recommend getting proper hides that have only one opening of an appropriate size. You need two, one for the cold side and one for the hot side.

So, long story short, he may not feel like he has a good hide at the right temperature, and he is trying to get out to go find something better.

He's also a wild animal, so all other things being correct, he could just be testing his environment. Our little derp stopped doing that as soon as we were feeding him correctly and had his temperature and humidity dialed in.
