Its like a clear ricordia?

[Tom S.]

I have searched for every word I can think of to describe this and I'm not finding anything close. It looks like a clear ricordia mushroom. It's a circle in shape. It was floating around earlier. I though maybe a coral shed some polyps or something. Now it seems to have perched in the corner of the tank. Anyone have any ideas? Should I pull it out?

Do you have images under white light (ex. with a flashlight)? Might be snail eggs (though these usually stay attached to solid surfaces).

Is this better? I could adjust the color on the tank if that'll help.

Snail eggs? I would imagine I should leave them if that's the case. Any chance these could be bad for the tank?

What snails/other invertebrates do you have?

Nassarius snail, certh snail, pin cushion urchin, conch, Mexican turbo snail, cleaner shrimp.

Looks like eggs to me but who knows I'm definitely not an expert.

I'm thinking this is it.

Looks to be it! Didn't initially guess cerith since I've only had them lay egg chains that look like this. I almost forgot different cerith snail species lay different patterns of eggs.
Nassarius snails lay eggs in flat sheets, urchins and Turbo snails release clouds of their eggs and sperm into the water column, conchs lay stringy egg masses, and cleaner shrimps carry their eggs underneath their bodies.
BTW, I have had decent success with cerith eggs growing up to become adults, more than with Collonista snails though not quite as much as I have with dove and Stomatella snails.
