Something strange happened during the QT process of my Scopas tang. In QT with a small cleaner wrasse, 15 gallon under copper power, about 2.0 ppm (checked with Hanna checker daily). After about 2 weeks, the tang started developing white spots. I have some CP on hand so I made a separate QT, put the tang in there, and has cleared up since. Wrasse showing no signs of disease. Any idea what could have happened?? How could it have developed white spots under copper??
