Okay. I think part of my problem is that I have her in too big a tank. Would it be safe to put her in a small tub INSIDE the tank? Should I close it up? Tupperware style would work all right for this?

As to live food, I'm not sure where I'd acquire it. The pet store people said she was eating frozen thawed mice, so I imagine she WILL eat them, but I'm not sure.

Thank you so much for your help. It's much appreciated.
