I got a young Greek tortoise five days ago (about 8months old, or so I was told), we put him up in a nice place with half cocofibre half sand, and it looks to me like he sometimes bites into the substrate. (In the half that is cocofibre). I am firstly not sure whether he is eating it or whether he is doing something else, secondly Im not sure if (and how) bad it would be if he is. We started out with a 100% sandbase, but it seemed that he was doing the same thing there.
Should I worry?
