She seems to be doing okay. She has been hiding a lot more than usual, but she is still eating. I just fed them a few minutes ago and she munched happily on some mealworms. The wound seems to be okay as well, although I don't really know what I am supposed to be looking for! It is still very pink but seems to be closing in. I might be getting a rack system this weekend, so they would have been seperated anyway. If I don't get it, I will get a heater for a spare tank I have. I think moving her out would be the best option over all. Thanks for the advice. It still makes me sad to look at her little stump.
