Coral Banded shrimp eggs?

[MGM_]

I notice emerald green patch of bubbles at base of my rock? They are perfectly round so don't think it is bubble algae. It is a small cluster of translucent emerald green. I have cleaner shrimp and coral banded shrimp. Also have perc and a Melanarus but they have only been in tank 2 days. I also have some coral (frogspawn, blasto, some Zoe's). Only one banded shrimp but from the description could this be eggs or is their something sinister I should look for? Tried a pic but you can't see anything as the too small..

Bubble algae can be perfectly round, all of mine is when it's small. Shrimp carry their eggs on them.

Grr..Thanks..Did find some pics of various bubble algae and does look very close..Small patch at base of my rock. Going to try to cover with sand and see if that kills it off.
