Newbie mistake here! Shortly after I setup my tank I aquired a small piece of star polyps. I am sure you all know where this is going. Well heck yeah it spread! It is covering one of my really large base rocks that I really can't take out. It's on the bottom with several rocks on top. I am sure I could remove it but that would mean a lot of reshifting of all hte rocks and disturbing other corals in the process. Is this a dominate coral that will crowd out other corals? Can it be gotten off the rock? Should I let nature take it's course? -Rachel
