Can ball pythons safely climb branches thinner then them?

Do you have bioactive enclosures?
When I go on youtube and search for bioactive set ups and someone asks how do you clean the tank, they always say you don't clean it when it's bioactive since the isopods are there.
And I have seen many keepers with bioactive ball python enclosures which also have wood in there setups.

No, & honestly, I have zero interest in doing bioactive enclosures. Seems like an awful big hassle, & there's only so much the "little critters" can dispose of- you still need to pick some up. I've also heard of people having trouble keeping their plants alive. Personally, I love growing plants & insects...in my YARD! I strongly suspect that your impression that bioactive set-ups are somehow "easier" are very misleading at best. I've been keeping many snakes for a very long time- & what I do works well for me. If it "ain't broke, I don't fix it".
