Yep, it's a habitrail tube alright. Actually, half of one. They seperate into 2 pieces. That way, the T can excavate and burrow as it pleases underneath and still have the shelter on top. I've used them for a few different pedes and several T's as well. They seem to like them pretty good. Usually I cover them with dirt to make it darker for them as well.
I am keeping an eye for a good photo opportunity but I have a feeling that I won't see her out in the open until (if the eggs go full term) the p'lings disperse. *fingers still crossed*
