What are these fuzzy things....

That's pretty much the best way I can describe them. They are on my liverock and in my overflow...best pic I could get is the ones in the overflow against the nice black background, but even they didn't come out too clear. They are white, fuzzy looking, squishy feeling , don't move as far as I can tell, and about the size of a fingernail. There is an almost transparent small little "tube" that extends out the top just a little bit. Is this something I should be concerned about.

+1 They are called Q-Tip sponges and are a great filter feeder in your tank, most of the time they all die off as the tanks gets more established.
