White spots

[katiethree]

I have these white spots which periodically appear on the rocks, usually 30 or so at a time, clustered together. Sometimes they stay, then get greened over, other times they have disappeared. They are oval, slightly domed and a little less than 1/8" long.

I assume they are someone's eggs, but can't figure out whose. I have 2 tangs, a clownfish, 3 green chromis, a blennie, green dragonet, red leg hermits and various snails. Tank is 9 months old.

2 tangs
a clownfish

and various snails.

rule them out.
the clown doesn't have eggs like that nor does it reproduce asexually
rule out the hermits, as they don't lay eggs the female carries them? right?
rule out the snials because usually they deposit them in a mass or trail ... but who knows. i just think it's likely that they are not the snail eggs.

It's tough to tell by this picture but when you say they appear and disappear I would say these are not eggs but are Moluscs of either the family Patellidae or Fissurellidae commonly called Limpets. These are marvelous algae and diatom eaters.
