I've had a large Regal Blue Tang (6-7 inches) in my 30 gal quarantine tank for about a week now. Things seem to be going OK so far, but he seems to be developing one cloudy eye. The other seems fine, just his right eye is cloudy. He eats great and is very active in the tank. What might this be and do I need to do anything about it?
