Strange White Deposits on Live Rock

I noticed several of these strange white sesame seed shaped deposits on the live rock. Anybody have a clue of what they are? I posted several pictures along with new tank shots! Thanks.

Do you have any snails in your tank? They might be Nerite snail eggs.

I have turbos and narsariuss snails

Those my friend are snail eggs. I have them as well and given time, you'll also be finding them all over your glass as well. Even though I have a constant supply of these on my tank walls, I don't see any huge population explosion of snails. I can't pinpoint exactly which snails these are from, as I have several species in my tank.

yep, snail eggs. If you look at the tank in the middle of the night, you will notice hundreds og baby snails covering the rock (eventually). it's pretty cool!

They look like they could be limpets to me. Take a razor and scrape one off. If it has a hard shell on top and is fleshy beneath it is probably some variety of limpet. If it is basically soft all the way through they are probably eggs of some sort.

what's a limpet?

A limpet is a mollusc. Check out this article by Dr. Ron Shimek.

The little white sesame seed shaped things in the photographs are snail eggs. That much is not in doubt. I thought maybe they were Nerite eggs but if there are no Nerite snails in the tank, then I guess they must be from some other snail.
