Depends on the size tub and type and the snake you have in it. My baby rack doesn't have hides the tub is small enough to offer that secure feeling they look for. If your tubs are clear as mine are, then hides just offer a dark place to hide. if you us an ARS tub their gray and dark so the animal feels secure. It all depends. But most people that use tubs and not a rack will offer two hides just like in a VIV set-up..Originally Posted by AkivaSmith
