There's something growing on my fish....

Hi! My fish has a yellow fuzz ball growing on his "wiskers". Today is the first time I've seen it. He's still very active and and eating like normal. I change his water once a week and feed him twice a day. He builds nests and actually has a great one right now! I don't know if this is something that normally happens or if he's getting sick. :( Has anyone seen this before? What should I do?

nice pic of it but i cant even come close to telling you what it is. I can tell you what it is not from what i know about fresh water fish its not Fungus becase if it was the fish would not be acting like his normal self. Might be Ichthyosporidium but i don't think it is becase you would have seen the fish move slower and its belly would get bigger. Now is this the only fish in the tank if so dont worry if there are other fish there get him in a sick tank just in case so nothing spreads. But i realy think you have nothing to worry about.
