Symptoms and Treatment

When did you start noticing the symptoms? Two months ago
Have you started treating your fish? If so, how? Most recent treatment was with Maracyn II.
Does your fish have any history of being ill?
Yes, upon initial appearance of fin rot I mistakenly used bettafix with caused him to become increasingly lethargic. I cut that out, did a water change an he seemed to be doing better. His fin rot began again, despite normal water changes so I started doing aquarium salt treatment. Did that for 10 days with daily 100% changes and he seemed to be doing better with a little regrowth, but it again got worse.
How old is your fish (approximately)?
I got him about four months ago.
Here you can see the extent of his fin rot. Dorsal fin is really, really tattered. Anal fin also deteriorating. Both have a little regrowth due to maracyn II treatment.
Here are his eyes. Now, when I first got him they were like that (hence his name - Steve Buscemi). Due to his reoccuring sickness, I'm now wondering if this is pop eye?
