Any advice would be appreciated. I've got a flame angel in my 75 gallon tank for about 3 weeks. His right eye has become slightly discolored, almost cloudy. Eating fine, swimming active but the eye is certainly looking different than when I got him a few weeks ago. Only noticed this today so I think it just developed. I don't have a quarantine setup but can throw something together tomorrow if needed. I'm not sure how I would catch this angel with all the rock work. I've got a bunch of soft corals in the tank. Other fish (2 small clowns and 3 chromis) look fine. Any suggestions?
