I acquired this creature from an LFS for free (who just wanted to get rid of it), dubbed "the mushroom of death" because it has killed and consumed everything it has comes in contact with (several fish 2"-3" fish, a large feather duster and was even seen expelling a plumb-sized (and digested) sea urchin. I think it produced a casualty or two in the original owner's tank (who had acquired it from another source, he received it when he ordered a bulb tipped anemone, which this thing is not and gave it to the second LFS).
It's believed to be a mushroom of some type with strong anemone qualities or some sort of species which falls between mushrooms and anemones and is in excess of 4 inches in diameter (the 'stalk' is at least 3" thick) and packs a powerful sting. It is stationary and wasn't mobile during its month stay at the 2nd LFS. Any idea on what this "mushroom of death" actually is? (I'm keeping it in a 20gal containing excess anthelia and a couple of hermit crabs):
