I have a 6" blueface angel that I noticed to have a white mark on each eye a few days ago, and tonight I noticed that it is not getting better but getting somewhat worse. One eye is getting a bit cloudy. I have had angels in the past that have had eye issues (5 years ago), but I have had a majestic for 2 years that I recently traded that had no eye issues at all. No other fish in the tank has any eye issues that I can see. I do not see the angel scraping its eyes on the liverock either. Any thoughts would be appreciated.
