Hm, does she show any interest when you offer food? Are you feeding live or f/t? She should be pretty well settled in by now. As long as she isn't losing weight, it's nothing to worry about if she isn't eating for the time being. When she is hungry, she will let you know when you go to feed her the next time around.

You could try feeding her in a different tub if you wanted to, and completely covering it up to see if she will take it that way.
