Round thing, looks like sesame seeds

[125mph]

These strange round things started to appear on my rocks.. Even my snail shells have them.. what is it? They look very small, multiple of them, and look like sesame seeds:

It’s hard to tell from your picture but I’m guessing either a species of coralline algae or eggs of some kind. Are they soft? Do they move in the current? Did they just appear? If so, then probably eggs. If they are hard, you have to scrape them to get them off and are a light purple/white color then they are a form of coralline algae. I have them in my tank. If neither, then I’m out of ideas.

Ahh I see.. it must be a form of coraline algae.. I never had this before until now.. strange.

I can’t see from the picture what looks like Sesame seeds. Do they move? Could they be pods

No they dont move. They are hard, not soft.. The picture is hard to see.. I can scrape it off and it just falls to the bottom. They look like sesame seeds that you eat on tuna!

Maybe calcium spots. I’m assuming they are white. I’m sure someone with more knowledge then me will be around.
Can’t you get a picture with less blue light.

Your name sounds fun and interesting

Are they spirobid worms?

Are they spirobid worms?

I can't tell from the picture but when you said on the snails that was my first thought as well.

Probably Nerite snail eggs!! But hard to tell with the blue lights on.

This is what I’m thinking, my last tank had them all over the rock and any dark place overflow and sump.

Wow i think this could be it.. I just brought a huge pack of snails and cleaners from reefcleaners, and in the pack was 26 nerites.. This was just a month ago.. Before this, I never seen these things before.. And I never had nerites before.

So they will hatch and I will get more snails?

Definitely Nerite snails eggs then. I honestly have never seen them actually produce more snails as my other fish pick at the rocks and eat them. So I cannot speak on this.
