I have a PB Tang that had what I thought was ich but now I am not so sure. The small white spots that had developed on him now have, for a lack of better words, small streamers coming off of them. While looking at the PBT I notice a nasty looking spot on a Yellow Tang. Both of these fish are in a 220 FOWLR tank. I can get them out but it will mean pulling the 240lbs of LR out first. There are currently 11 fish in the 220 and all I have for a QT is a 55. Can anyone tell me what I have and a course of treatment?
