Burrfish update and really need advice!

I am still trying to figure out if she has internal parasites. I had thought she had ich but it turned out to be bubbles stuck on her from the airstone in her QT. I had just started hypo (only got to 1.022) but stopped when I realized it was not ich. So she has not had a spot of ich for two weeks now, which is great news.

But the IP is confusing me. I couldn't tell if she had them or not. She ate well, was very active, colorful, breathing well, feces were normal, just no signs of IP except she was not really putting on weight. She did put on a little weight during the first week and a half but I felt it was not much and decided to start treating with Prazi-pro 2 days ago. I did a huge water change and dosed the exact amount. She did not eat the first night. She did not eat the next day. She still has not eaten and its been 2 1/2 days. Since starting the treatment she swims frantically most of the time, looks skinnier than ever and is very, very dark colored. He breathing is terrible at times. I am monitoring nitrates and they are quite low. Im using an ammonia remover to make sure they stay at 0.

I am having a very hard time watching her like this. She was doing so well in QT without the prazi, which is suppose to be so easy on the fish! She is EXTREMELY stressed.

Any ideas????
