pea green coral?

[PsiStar]

This is one of the last hitch hikers to ID on the live rock. It is ~3/8" dia. Would like to know what it is if for no other reason than to sound like I at least have interest .. and fain knowledge.

It could be a green button polyp, or a aptasia kinda hard to tell when it closes does it suck into the rock or does it close its head leaving the stock exposed?

 

[PsiStar]

It closes its head leaving the stalk exposed

I googled "green button polyp" and the pictures that produced look very much like what I see during the day. That is good, right?

Yes, it's a good guy!

+1. That's a green button for sure.

I have a whole colony of these, very easy coral, spreads quite nicely.
