I don't as of now, think its TB.
The main symptoms of fish tuberculosis are loss of scales, loss of color, lesions on the body, wasting, and skeletal deformities such as curved spines.
I am not seeing any of that - other then the spine thing and I think that may of been a birth defect. The pictures of fish TB I have seen online - they don't really look like her. No missing scales but she does have a rash? I did a round of Furan 2 but I'll get some kanaplex just in case. It might just be her coloring too.
I would think she would also have clamped fins, which she does not. She pretty much acts like a healthy fish
