I have a bannerfish with bulging eyes. They don't appear cloudy, but they both are definitely severely swollen. It is also pretty obvious the fish has reduced eyesight and isn't able to eat much, if at all. Thinking it was popeye, I have been treating with Furan-2 and Epsom salt, as recommended in other threads, for the last 3 days. However, there doesn't seem to be much, if any, improvement. Any thoughts on what it might be or if I need to try another treatment? Thanks in advance!
