Does anyone know the name?

Ok, these guys were hitch hikers on some live rock I bought a while back. I was wondering if anyone might know the name of them?

These are very accurate color representations of these guys. They are large, about nickle size if you include the skirts, but don't act like palys (they don't feed like my palys do). They are also quite prolific.

Whatever they are, they really light up a tank!
