Still continuing salt and metro, and I have bumped up the water changes to 75% a day from 60%. Not sure if she will make it - I hope this us just a phase and not a turn for the worse. Still have at least another week of treatment. I'm not sure what else I can do and am feeling frustrated.
On a positive note, the original fish who was showing symptoms looks 100%, and I swear he is bigger now than he was 2 weeks ago. Looking at him you would never know he was sick.
