Bill is a great guy. I bought many of my first darts from him at Lee Watson's Swap Meets. My auratus would go through phases where one would be real bold, then it would hide for a while, then be bold again. So hopefully yours stay comfortable and bold in their environment. I had three from him at first, and then one magically disappeared and I never saw it again. I think it was due to the corkbark that I used, it might have hidden behind it and never eaten and died. Or is used it as a ladder to escape through the lid (if possible). Now I think that I have two females, but they are so active. Rarely do they ever hide. Good luck with yours! Great Choice for a first frog.
