Forgot the name ... please help recognising this (I think) LPS

Hi, I almost have my l(small) list of inhabitants complete, but forgot the name of this (I think) LPS, see picture. Does somebody recognises it?

GSP otherwise known as Green Star Polyps.

It looks like green star polyp, a soft coral.

I don't think it's galaxia coral given the lack of a noticeable skeleton and a differing number of tentacles around the polyps (which don't have that mouth-type formation from the picture).

GSP, or Green star polyps as posted above. A soft coral, and what many would consider a weed.

I tore my biocube down and nuked the rock due to GSP.

Thanks for the quick replies @homer1475 and @brawthy ! It's in my tank for a year and hasn't grown substantially, maybe because surrounded by sand...

That’s a green pipe organ coral...which is a soft coral

 

[ameerun]

Funny, we now have different opinions. Looking at pictures from both suggested answered, I'm inclined to think it's the green star polyp ... but how to be sure?

 

[James M]

Pipe organs are not fast growers like gsp.

Is there a soft mat that it's growing on, or a skeleton?

Pretty sure its a pipe organ coral. Green star polyps Ive never seen in that shade of green and also gsp has purple stems and mat.
