Please Help Me Identify These Dots

I'm starting to see a few of these appear every day.
They're about 2mm diameter.
They have a pretty solid grip on the rock and are hard to break. I use metal tweezers to crack and scrape them off the rock.
I have softies, LPS and SPS, but I don't see them on any corals. They're only on the rocks.
They must move very slowly or only at night, because I've never seen them move.
They appear grayish in the shade, like in the pic below, or white if brightly lit.
Anyone have any idea what these are? Thanks!

Those are nerite snail eggs. Harmless

They will fall off on their own eventually.

Makes sense.
I recently got Nerites from Reef Cleaners. Then eggs started appearing.
Mystery solved.
I hope I get more Nerites in the tank.
Thanks guys!
