Hi, I have a 29 gallon aquarium. It's been doing pretty well so far, up to now. No diseases have ever been introduced (except ick, which I got rid of very quickly), and the fish all seem healthy. However, One of my Black skirt tetras seems to have an eye problem. The fish's eye seems to "pop out", and it's bulging like crazy. The weird part is that only one eye is that way.
Other fish also seems to have bigger eyes than usual, but nothing compared to this. Anyway to solve this problem?
