We recently moved ours into tubs. 300-400 gram snakes into 41 QT steralites, with two reptile basic hides. The move was flawless. They were all established snakes here. We left them be for 3 days until feed day. Everyone ate without hesitation. Week later, 3 out of 5 in shed. Bumped humidity, perfect sheds. You would never know they made a transition.
