Pearl looking balls next to Zoa

they are fairly hard when touching. Any idea what the little grey shiny balls are?

Bubble Algae??

 

[Ptinetti]

Are they bad? I thought maybe eggs at first, but everything I have in tank is very small.

I've never delt with it myself. It's a nuisance algae. Be careful when you move it it can spread quick. See the below listed thread.

Looks like bubble algae to me. Try to pull the rock and gently pull them off of the rock. You don't want to pop them.

I wouldn't worry about popping them, I have before and never had it spread. I would just try to pull them off and toss them in the trash.
