Can someone please help

[Durango]

I bought this live rock yesterday and I can't figure out what are this little plants are??

Hard to see but it looks like star polyps

 

[Durango]

Are they good or bad I'm not really sure?

 

[Rscomia]

They are not bad in the right conditions they will spread like a weed so you might have to keep them trimmed back if you dont want that many

IMO Aiptasia or some kind of anthelia, google a little to see which guys you have. I can't tell very well from the picture
