Answer
Hi Gary,
Thanx for your question.  Basically, yes, this is about all you can do until the fish recovers.  What I would do change the water every day so the water is fairly clean and the chances of infection are reduced.  There is also a product you can buy at most nurseries that have a watergarden specialty which assists the fish in building up the slime (necessary for them to fight off diseases) on the fish's body.  I don't recall the name but if it looks like the fish isn't healing naturally you might want to check into the slime medication.  I hope this helps.
