BB size Bubble

[Brian65901]

Can some one tell what this can be. I can't take a good picture of it but on one of my zoa rocks I have what looks like a shiny glass sphere its about the size of a green pea. I just have one for now. I remember seeing them on dive trips in the Caribbean From what I recall they were hard to the touch.

I Pulled the rock put in a container and removed it being careful not to rupture it. I couldn't believe all the pods that came off the rock when I rinsed it. Now I know what my CB is picking on all day
