Ok so outside the tub is what I will do. I'm just wondering if I should use cocofiber or just some paper towel for substrate. Thing is my ball is still young and don't want to change too many things and stress her out, she's doin great right now, very good eater and just had her first perfect shed the other day. I will be using 1 of the same hides, she outgrew her other hide so I'll need to find a new one. These tubs are not totally clear, they are kinda fogged out. Should I still be using 2 hides? Iv herd others say u don't need any when using tubs but I just want to make sure.
