Pop Eye Help!

[Bigdaddypuff]

Hey, I currently have an tiger Oscar (hes only 3 inch) with pop eye. I bought Pimafix antifungal Fish remedy for it, Will that help him? I have a 55 Gallon tank right now.

"Pop eye" can have several causes and the treatment for each is different, apparently.

Are both his eyes looking infected, or just one?
