I have a glass lizard that needs a fairly deep substrate to burrow in. At first, I was using a deep, round water bowl that sat directly on the bottom of the tank, but I decided to switch to a broad, shallow one so she could soak if she wanted to. The substrate is too deep for this water bowl to sit directly on the bottom, so the lizard tunnels under it and hides there. Is that dangerous? Could it crush her somehow?
