Tang broke out in what I thought was ich. I was torn between treating the whole tank with cupramine or hypo'ing the whole thing. After a few days I decided on hypo, and spend the time making tons of RO and trying to catch the fire shrimp in the tank. After finally doing so and moving them into my almost ready 75, I moved all the corals over and dropped the salinity. At this time, I realized that this was not ich and instead was a bad case of flukes. I turned off the lights and easily caught AT with a net and did a 5.5 minute RO dip. It cleared up most of the flukes. I think that the RO bath was not as effective as it could have been because he is coming out of hypo water already and the difference in osmolarity was not great enough to take care of all flukes. I can still see a fluke on his eye and maybe on his snout but most are gone and he doesnt shake his head anymore (for now).
Not being sarcastic or condescending but this is the reason why I prefer to QT all new arrivals. Prazi-pro, hypo and RO dips stress this fish....I understand you have no alternative but you now have to treat and also stress your other livestock. I hope everything turns positive for you...
