Hitchhiker?

[myersb33]

I added this colony today and noticed whatever this seems to be opening and closing on my coral. Anyone able to ID this?

The video doesn't show up for me. If it had it's thumb out, that's usually a sure sign it's a hitchhiker.

Bivalve most likely

That's what I was thinking. Possible scallop? Doesn't look like an electric or flame though.

Not likely. Common bivalve tend to anchor in one place. Scallops move around

Yep bivalve or a small clam/scallop from what I can see. Nothing to worry about really. You can always glue it shut. The Zoa’s will grow over it. I have a clam hitchhiker and my Zoa’s killed it for me...lol.
