Just noticed my yellow tang pooping while he was devouring a seaweed clip and it was white and got to like 2 full inches before it broke.\n \nDid a little bit of googling and I've heard that this comes from A.) Internal Parasites and B.) Indegestion?\n \nI didn't know fish really got indegestion. But it doesn't seem like a parasite thing, I would think he would be kind of skinny and sunken in at the stomach if that was the problem but this tang's gut is fat and happy.\n \nI also did QT him before it went in the tank. I dunno if copper really kills internal parasites though. He's been in the tank for a few months too, I might've just never noticed or it may have really just started.\n \nAny ideas?
