jbetti, these fish are in your display tank, correct? I recommended the hypo because you already used copper in the tank and hypo will not harm a tank. There really is nothing else that can be done in a display tank. Antibiotics could have been tried, but not in the display.
You will need to get a QT up and going, if not now, then in the future. You just can not treat fish with meds in the display.
