Mushroom tumbleweed.

So yesterday I added some new coral to the tank. I was cleaning the glass and noticed one of my blue stripy mushrooms kinda just floating around in the tank with the current. I didn't but the rock they are on or anything. What would cause one to "let go" and go for a swim? All the rest of the colony seems fine. Today it is still just kinda floating around in there. Any thoughts?

My superman shrooms do the same thing. Matter of fact I've got one floating around now too-they don't like where they're at so they'll let go and find somewhere else to settle in :)

Not sure if its a common happening or if it fell off, but I would definitly get it under control. Hate to have it blow onto one of your nicer corals and slome it to death. Mushrooms pack a good punch.
