Hitchhiker ID

[johnyboy]

Hey guys,

It seems that I have some type of polyp that hitchhiked into my tank. Can anyone ID this for me? It's taking over the rock work like star polyps and I want to get rid of them before they take over everything. Any methods of getting rid of this ?

Looks like clauvularia or anthelia...but I'm not sure on eradication...sorry
