I have a problem with my goldfish, he has a weird "worm like" growth out of his side, it looks like the scales are moved and a thin white 'wormy" thing is growing out of his side, this is the second time I have seen this and it is one of my favorite orandas. Anyone have any ideas??? I need help, I don't wanna loose him, I lost the last one, does it sound like a parasite? or a cancer?
