I agree with hondatech. Sorry, I didn't mean to say that vitamins and supplements will cure the virus, but help the fish through more easily.
I would leave him in your display and keep an eye on water quality. Moving him to another aquarium will probably just stress him out.
With regards to micro bubbles, it's not such a good idea to have them in your display tank. Do you have a skimmer and flow pumps?
In terms of vitamins - I use bright well aquatics vitamarin-m and c. Basically you've gotta wait it out and provide your fish the best water conditions and nutrition.
