Thing I like about ball pythons is that that aren't a very good display snake, but you can always take them out and handle them if someone wants to see them/ you want to show off without really worrying about them being aggressive. I love my rack, and it saves tons of space. I use white paper towels as substrate and it looks fine to me. No need to fix up a tub unless you want to. But you could make a tub look great and I've done it before but with multiple snakes I like simplicity. But I do pay attention to my snakes and how they eat, act, etc. and I've noticed my simple setup of paper towels, water bowl, and 2 hides works great, it's very efficient, and my snakes seem happy.
