I already have a pretty big cork log (hollow) in my tank for my bp on his cool side.
He loves it. Well, I don't know if he "loves" it but, he finds it very cozy.
However, I regret buying him it because once he is in it, it is impossible for me to get him out. I have to wait until he gets out on his own. And let's face it sometimes that can be awhile. :cool: ahahha
