About 3 weeks ago I had a blue Tang (Paracanthurus hepatus) break out with what looked like Ich. I raised the water temp to 82, fed food soaked in garlic, and did a FW
dip on him. He was looking and doing great until this weekend. He looks horrible white spots all over him maybe even a a white film. I spoke with a guy at my LFS
he told me to do another FW
dip(which I did) and try to manually rub off the film. This morning he looks even worse and is running all over the tank scratching, stopping by the cleaner shrimp etc... The spots this morning look black??? Now to the point: Does there come a point when you have to worry about the safety of the other fish and dispose of the sick fish? I am not set up yet for a quarantine tank as this tank is in my office. It is a FOWLR
and I do not know what to do, any advice you can give would help.
