Also, I'd suggest watching out for your ball python's size and ability to fit through the hole of that dark snake cave hide. The 2 piece one with the hole in the top right beside your bag of substrate in the first picture. I think its an awesome hide yes, I'm using an exoterra version of it for my 250g guy too, but the moment the hole gets fitting for him, I'd remove it. They're known to be deathtraps as balls too big for it get stuck half way, I read an article on it and freaked out so yeah being very careful just note down the space he has left whenever he crawls in and out of it. And depending on the growth rate of your ball, it could be pretty soon. Some gain a few hundred grams in merely a few months.
