[Koresample]

I purchased what i thought was a Curley Que anemone, but after looking it up on the web, what i have doesnt look like one. Can anyone identify it? It is about 7" in diameter when it is open. Will i have concerns when putting other corals in my tank with this? I know i should have done more research now before i bought it. I also have something growing out of my live rock (also pictured below). The picture isnt all that clear, but at first i thought it was algae and when i went to pluck it out, it pulled itself back into the crack in the rock. it seems to be reddy brown in color, and the arms of it are about a quarter inch and growing.
