Recently I purchased a 30 gallon aquarium for Sage to upgrade her from a 10 gallon. The new larger tank holds much more substrate and I've probably put more than necessary into the tank so that it is fairly deep. I've been noticing now that at night, instead of going into her favorite hide like she used to do every night, she burrows into the bedding. This morning I actually thought she escaped because she was completely submerged and had to dig a little to find her. Has anyone else noticed changes like this when changing enclosures, or have snake that do this? Just curious how many people have snakes that burrow vs. going into hides.
