Is this algae?

Sorry, noob question: what is this greenish thing with a yellow lined circle in the middle? They seem to spawn in the last 2 days. Thanks!

Looks like some kind of cup coral. Was that live rock?

They look like barnacles to me.

Colonial tunicate.

Tunicate.

Thanks all! Did some google search , I don’t see any live tentacles or things inside the circle, so it seems more likely to be tunicates. I will keep an eye on how it develops.
