Looking through your posts she was 600g a month ago. At that size I wouldn't worry about it at all. I have a 380g female that stopped taking f/t when I got her. I fed her live for a little bit but I'm tired of driving to the pet store every 5-7 days. So she hasn't eaten since January 10 but she hasn't lost ANY weight, so I'm just holding out until she goes back to f/t. If you really get worried though I'd try a live rat to see if that works.
