My roomate and I just bought two torts. Her tort seems much more lively than my turtle and it is really worrying me. The pet store worker said that they are probably a few months old. (But what does he know, especially since he seemed very incompetent)

I'm not sure what to do, I have soaked him for a while, and he eats only occasionally; when he does eat he goes right back into hiding underneath this log I bought for them.

WHAT DO I DO?? Could he be sick? Its not very humid in the tank, is that the problem? And what can I do to make it more humid?

--Thank you!
