Need help id'ing little white bumps

[gordongregory]

Can anyone id these little white bumps that are appearing on my live rock? They are about 1/8 inch in size and smooth.

Sorry, I dont know what they are but I have them to. I think they may be some sort of egg sac.

I thought they might be some sort of egg sac, too. I wonder for what sort of animal?

do they move at all? take a picture of the same spot in a couple days... maybe flat worms?

 

[gordongregory]

They don't move but do disappear leaving just the remnant edge like they've hatched or something.

then they prolly are egg sacs... my guess would be some type of snai, (I had nassarius snails that laid egg sacs similar to those, but only on the glass.. (they were semi transparent, and you could see the eggs inside)

Cool. They don't seem to be a problem but I was curious since there are a lot of them and they are mostly on the brightest spots of my rock near the top of the tank, thanks.

no worries! the strong shall survive.. the rest shall become food for the tank.
