Ok so today starts day 3 for my regal tang in my DT. Friday she was good. Saturday I did a water change and thought that stressed her out and was immediately thinking she was dying. Yesterday she was good, actually started to come to the front of the tank to eat. And now today she has a white spot on the side of her body just in front of the black stripe. She ate well and seems to be swimming fine. However I can't tell if her breathing is labored or if that is how she normally breathes. Her gills are opening and closing faster than my 2 clowns but I don't know if that is typical. I started treating her food with Metronidazole and Focus. If I can get a picture of the white spot I will post it as soon as possible.
