Need help with ID please.

Hello, I've recently started a 25g nano with some live rock from an already established reef tank. I've had quite a few hitchhikers including this, which I'd appreciate some help with identification. There are about 8-9 polyps growing on one of the rocks. They started out as nothing and in two weeks have grown to about 4mm.
My best uneducated guess would be some kind of clove type coral.

They look kind of like those dreaded blue clove polyps IMO. They start out as a harmless little patch, but after a few months under the right conditions they'll be popping up everywhere in your tank. Be careful.
