An anemone, but those are inverts. Higher chance of a wild caught clown to host an anemone than tank raised. Mine (tank raised) has hosted a torch and elegance regardless of having an anemone a couple inches away. I wish it didn't b/c it seems it just agitated it. Some host hammers or mushrooms. Many things.
