Tonight I just noticed one of my Blue Reef Chromis with a problem that I have not seen before. I love these little things. I have quite a few of them and i especially like that they will school. It's amazing to watch. Tonight I noticed that one of them has what looks like a shiny bubble above his eye that is displacing his eye laterally and downward. Has anyone ever seen this before and what is the treatment/prognosis for this?
