Another feather duster question

[Ms_Jerk]

I sat down the other day and was just looking at my tank. I noticed that there were a few feather dusters and then I realized there were 7 (all on a rock except for one, in the sand). How big do you think they will get? Can I remove them from the rock? They aren't very big right now.

They are good to have. They come in all sizes and the ones you see are probably full size and won't get any bigger. My tank probably has a hundred little ones in it, some no bigger than 1/8 of an inch. No you can't really remove them.
