Found these with some zoos

[pweissma]

I bought a fairly large colony of zoos on auction at the Brooklyn Aquarium Society meeting tonight and found several of these on the rocks and shells attached to the zoos. Central disk, 6 arms, 3 big, 3 small. Haven't yet put them in my tank. What is it? Thanks.

Thought it may be a serpent star. At least that's what mine looked like.
