Need help fast....

If it is Marine Velvet. Cupramine is probably one of the only ways to get rid of it. Be sure to move your fish out of your display though and into a quarantine tank. You don't want residual copper in your tank whatsoever.

If it is ich and your fish are still eating, I would just let it run its course. As long as the fish are eating, they will generally fend it off. The time I had ich, I added Garlic puree to their food to help boost their immune system.
