Cool. I noticed one of those in my tank a couple years ago. Now they're all over, and even start growing on the glass and power heads! Very nice.
When we got our first piece of live rock, there were two feather dusters on it. One was a tiny red one, with a white tube growing on the side of the rock, the other was striped brown and white,with it's tube inside the rock. Coraline grew over the red one, but the brown and white one is still there, now about the size of a nickel. I really like them, so I'm glad to find this new one too.
