ID help, good or bad?

[Ionclad]

I found these in my tank a couple days ago (72 gallon). They are very small, about the size of a pin head. I added 2 frags 3 weeks ago, but these appeared on the other side of the tank. They open and close throughout the day. Any ideas?

Can you get a closer and clearer pic?

I don't think I can get it any better than that. I had to use a magnifying glass to be able to get that shot. They are very small, like I said, about the size of a pin head. There are about 20 of them in a 1 inch area at the base of a rock.

Probably a zoa or paly

Thanks, I will keep an eye on them for awhile.

No idea if I were you I would observe them and if they do not seem to be a problem then I would let them live i love the small things that live in my tank.

I enjoy checking out new stuff also, but this is a 2 year old tank and the only new stuff in 9 months is 2 sps frags that went in 3 weeks ago. Time will tell and the enjoyment goes on.

Yep, it look like, just can't see the flesh connection between them, and isn't shown what's around this polyps.
Can you take shot of the area where this are, and what's around them ?
