sea slug?

[pupeluv]

Today i saw something i think was a sea slug laying eggs just above the water line. I tried to get pics but the thing was too small (about 1/8 inch). I don't have any books on inverts yet. It's cream color with brown feather-type markings. I haven't seen any antennae. The eggs it laid looked like miniature pieces of rice. If you think it's a sea slugs, would they cause damage? I just have live rock and some caulerpa right now. I'm wondering if I should dispose of the eggs or let them hatch. Can anyone recommend a good website to look at sea slugs so I could try to identify it? Thanks in advance for your help.

Never mind. The next night, whatever that was came out of the water and ate its eggs. Problem solved.
