I have these small white spots all over a number of my rocks near the top of the tank. Each one is about 1/16" and are oval-shaped. I actually pulled one rock out to examine and they can be scraped off with the tip of a knife and they seem to be hollow. They are almost like little seeds stuck to the rock.
Look at the rock the red Zoa frag is sitting on
