At the reptile expo, I came home with a new Ball Python who I named Trip, super healthy, beautiful face. Now, I've noticed him rubbing his nose against his tub, started off pretty mild at first and I didn't really think anything of it since all my ball pythons rubbed their first week home. Well, it hasn't stopped, and now I'm freaking out because his nose is starting to look rubbed and I'm extremely worried. I have 3 more Ball Pythons in the SAME EXACT setup (tub setup) that NEVER rub, perfectly happy, yet for some reason Trip just rub rub rubs.

Now, I really need to know how I can help stop this. I don't care if I have to buy him a new tank or whatnot, I'm just extremely worried about him. He is currently in a tub setup, and I think that perhaps it's just too small and boring for him? There's nothing inside but a hide, water bowl and repti bark substrate. I was thinking that perhaps getting him a 20 gallon enclosure with two hides and leaves and more things inside could stop this? Does anyone know how to stop this? I love him with all my heart and seeing him like this is killing me!

Now, problem is, I live in a small house. Trip is quarantined from my other bp, Sam, and has been for two months now. If I move Trip into a bigger tank, I have no choice but to move him into the same room with Sam, as there is literally no room anywhere else. I would never ever do this normally, but I feel it is more dangerous for Trip to continue rubbing for another month. Other than rubbing, Trip seems completely healthy, never refused a meal, zero signs of illness, mites, anything. I got him from a very nice breeder who I personally felt very comfortable with, all their animals seemed very healthy. He has been under quarantine and monitored for two months now....how risky is it to move him into the room with Sam? I don't have a choice really, but I'm still paranoid...thoughts?

Thank you so much...


Here are some visuals. First photo pair is the day I got him and second pair is him now.
I believe the reason it looks so dirty is because he is pushing substrate particles into it as well, I have tried cleaning it but it doesn't do much....I am devastated and so worried about him.....
