Hydroid Jellyfish?

[shoreliner11]

I saw this guy on my glass today and wasn't sure exactly what it was. I was thinking it was a hydroid jellyfish but I'm not sure. Can someone confirm or deny the id? It does have a bell shape, common of many jellyfish on the opposite side. Any related info on hydroid jellyfish(if it is) would be appreciated. Thanks

Almost looks like a baby brittle star. I had a bunch on my glass but my yellow tang got most of them. Does it move?
