Probably ammonia burns. Do you know what kind of care she had before she came to you?
If you have API Stress Coat, add a double dose in now. That should help her. The medication I would recommend for her is Seachem Kanaplex but it's hard to find it in stores and usually has to be ordered. I've gotten it from www.kensfish.com
but recently www.drsfostersmith.com
has begun to carry it as well. The next best bet would be API Furan-2.
