I have a tiny little fishtank in my room, only 10 gallons. I have 7 fish in it, 4 white clouds, 2 miny catfish, and 1 pleko (algae eater). Well last night i discovered there was some white fuzz on the back of one of my catfish (where he had a fin) and one of his fins was eaten away down to the bone. He was swimming funny and looked like he was dying. So i get home this morning, all of his fins are eaten away by some kinda fuzz and he's barely living... WTF happened? Anyone know of some kinda fish disease that does this? He's been fine up until I guess last night.
