It looks like bubble algea, not good. It can take over the tank. Just make sure you dont remove while the rock is in the tank because when you burst the bubbles thats how they reproduce

1. Valonia ventricosa, also known as "bubble algae" and "sailors' eyeballs"...

I have a butt load of these. Brought emerald crabs to try to get rid of them. Unfortunately, the ones I brought do not touch them. One of the emerald crabs must of molted numerous times because he has gotten big. I call him Hulk. LOL.

But I digress. Yes, these "sailors eyes" are very annoying. They ended up growing in between my 80+ head hammer coral and started splitting the branches.

Yep bubble algae......if your tank is big enough get a foxface.
