I'm afraid that the news on that front isn't very good. Most treatments call for
euthanizing all fish who have been in the same tank with the infected fish, and
using bleach and alcohol on the plants. By the way, humans can catch it too
(fish handler's disease; siphoning water out of the tank is not recommended), so
be careful with open sores.

There is a very well researched article on the disease here:


I had to euthanize and tear down a planted 55 gallon aquarium a few years back
when I put in a Melanotania species that was just in from Europe. Unless you
raise the fish from eggs, a lengthy quarantine for rainbows is in order.
