Green colonial hydroid / zoanthid?

[Paullawr]

Hi all

Noticed other day I have these small green polyps in random places on live rock. Tank been setup since January so these are the latest things to emerge

I have no plans on irradiation unless become problematic but was curious as to what they might be.

Best description under a 6K white light is green with white ring.

Pictures aren't great but then they are about two mm in size.

Look like this.

Nah cannot see any lashes like the above. More solid colour rather than translucent.

May have to wait it out and see if they grow bigger.

Its an algae. Whether same species and will growaege I don't know. Small at moment.
