Need help id'ing little white bumps


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

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.
