Are these round green things eggs?

I noticed these round green things a couple of weeks ago only in this one spot up high in the tank. Are they eggs of some sort or a green algae? I have seen a little bit of green round algae that looks like glass (bubble..just put in two emerald crabs) but this is dull and more round. Any ideas?
Water tests perfect.

they look like closed up zoas to me

Can you get a better picture?

 

[stormystormy11]

I can't seem to get a better picture but there is more of them now and they are attached by a small stem. If I poke them, they are soft. I have a lot of zoa's and so I know that is not what they are. Any other ideas?

I think it's algae. I'd pull it out if I were you.

 

[WooA]

From the pic, are they above the zoa colony than? Almost looks like an infection in that part of the colony..?

yep above the zoe's. I found out it was grape algae. Can overtake a tank. I pulled it out after letting it grow for a couple of weeks.
