Help what is this?

Hello,

I'm new so I hope I've put this in the right place!

I've got this pink creature that came with my polyp rock. It has grown considrebly over the few months I've had it. Every night it moves arorund the rock and yesterday it ventured off the rock onto the glass. I never actually see it move it seems to do it when we have all gone to bed.

I originally thought it was an anemone but after it moved i had a better view it seems to have a pink body with ternticles coming out of it's back. It has green/yellow tips to the tenticles.

I've asked the place I bought the polyp rock but they don't know.

Has anyone got any ideas? If you do is it harmfull!!!

I've attached some pictures.

Also any idea what the thing on the glass in this pic is?

I want to say aiptasia but it looks really weird... whatever it is it seems to be multiplying judging the little guy on the glass.

Looks like aptasia on the glass the one on the rock looks a lil different . But definantly a pest dont try to scrape it it will spread like a wild fire. Gl.
