The Gist of the story winter pipe organ had been doing good, had fallen off and stopped opening and I had run into some swings and stuff so I assumed it was that. I picked it up today and saw these fuzzy white tube things growing off of it, and previously was the happiest coral in my tank producing new little polyps daily, now out of the whole coral 4 to 5 little polyps will open. What are these things, are they bad, can dip remove them, what to do... Any insight helps! Bonus there is a little brown thing on the flat side of the plug that looks like a microworm, Does anybody know what that is? I see them from time to time.
