majano anemone. bad, VERY BAD. They will take over your tank if you let them and they will sting and destroy any coral that they touch. They're easy to remove, try joe's juice, boiling water, lemon juice or aiptasia-x and inject it into the center in their oral disc. SMOTHER THEM and you should be good.
