Hi everybody! I'm your newest Tortoise Forum member. We got our Russian tortoise just a couple weeks ago. Previous owner said he bought it from PetSmart 3 years ago. I did quite a bit of research before and since getting it. That's how I found this forum, and decided to join. Everything is going well, except for one thing. It paces back and forth in its encloser all day. It is a glass aquarium, but I have put a 5 inch high piece of card board around the bottom of the whole thing. Back and forth all day. Is it going crazy?
