Just as a follow up on this, I started seeing less and less problems over the course of a few months, and eventually no problem at all.
I consulted some of the very large fish farmers i know and they said i could either spend a bunch of money on antibiotics or just let it run it course, and they were correct.
Over the last 6-7 years, this problem has not come back, so to anyone else that sees this on theirs, there is hope and time does heal.
