I would just get the large RB hides for 548g snake. I used the large ones for my girl when she was about 500g and she grew into them fine. And yes, they move stuff around a lot when they are hungry. My girl will knock over her Acurite temp thing and then flatten it into the aspen plus push both hides around and shove aspen all over into piles whenever she is hungry. Get used to it lol.
