Popeye and white spot...

I moved my tank about a week ago and my fish obviously hated it but they are
OK now in general.

Except my Coral Beauty who has popeye. He has had it for about 3 days now -
any ideas what to do to get rid of it. He seems a bit skittish at the
moment but is still feeding.

My regal tang was rubbing its tummy on the rocks a few days ago and had some
ich on him as well so I have been dosing with Myxiazin which seems to have
worked on the tang - the ich is 90% gone now but he is still rubbing
occasionally and is also skittish although feeding quite happily.

Any ideas on what to do from here? I want to stop with the medication from
today as I have doesed for 3 days now.

Thanks,
Mike
