I've got a mat type coral. It has a red base with bright green polyps. I noticed a few white, cotton looking things about the size of a pea on it while I was doing a water change. Normally, one wouldn't be able to see the things but all the polyps retracted and there they were. I knocked one off rather easily, so I know it wasn't attached. It floated around. Should I be concerned?
