I'm about to buy a 1200 gram ball python, and I just bought a 30 qt tub for him. Is the size good enough, or should it be bigger/smaller?

I also noticed that if I have 2 hides in the tub, he gets very little space outside the hides (what I mean is that the hides covers much of the space). Could I have only 1 hide on the warm side, so he can have some space to move on the cool side?

That's basically it, some answers would be awesome !
