Spots on shells, sides of tank

[Lilxxwojo1]

Found these white dots on some snails, the back wall, and some of my live rock. Anyone know what they are?

I believe those are snail eggs.

Haha they look very happy since they are smiling at you!

Snail eggs are laid in a rather specific pattern, and are usually smaller. Hard to be absolutely sure from this picture, but those could be pineapple sponge, tiny limpets...
