I noticed when I bought my Powder Blue Gourami, that he had part of his fin missing, and it seemed to be haeling very well. Today I looked at him and noticed that he has a fuzzy ball on him, about the size of half a pea. It is not totally attched to him, so I am able to pull it off. I haven't yet, and I was wanting to get some help off of here before I do anything. If it is Ich/Ick, what are good treatments?
