HI, I hope someone can help me. I have a tank with several bluegills who have had no issues or illnesses for as long as I've had them , about 2 years. I introduced a couple of green Sunfish to the tank without quarantining them, yes, major mistake, and now my bluegills have white fuzzy patches growing on them. The new fish don't. It's not ich. It's only on the body, not the fins but I've never seen it before. I am treating with Waterlife Protozin, White Spot and fungus cure and on day 5 there is no improvement. I was thinking of trying Melafix or Paraguard next. I'm going out of town Thursday and leaving my sister in charge and I need to get this under control or I'll be worrying the whole time. Any ideas what this is?
