Hi, I have a Kole tang who today shows about 5 white spots. 2 on one side and 3 on left pectoral fin. I had this fish in QT for just under 4 weeks with 4 mollys for observance and to make sure the tang ate readily. 2 days ago, I moved all 5 fish into display. Yesterday, everybody ate well, kinda got along with other 3. Not sure if I should put him back in the QT and treat with copper or just make sure he doesn't get worse. I also have a 25 watt aqua UV on this tank.
Please give advise.
