Strange White Deposits on Live Rock

bg3489 · 03/13/2007, 09:17 PM

I noticed several of these strange white sesame seed shaped deposits on the live rock. Anybody have a clue of what they are? I posted several pictures along with new tank shots! Thanks.

snail eggs?

I dont know if they are snail eggs? But they ar snails. Is you tank relativly new? I had them on my tank when I first set it up, And I would just slowly knock them off when I cuold and nothing realy ever came from it. If I remember what the name of the snails are i will reply again.

They are called vermatid snails

Spelling correction: Vermetid snails

I don't think they are vermetids. Can you get a closeup shot of one or two of them? Really hard to see the definition. My first thought was flatworms, but the color isn't right.

those are either Nerite snail eggs or some kind of Foraminifera AKA Forams. cant really tell from the pics. its possible they are spirorbid worms but i dont see any spiral in the pics.

I have seen small narsarissus snails runnin around but I wasn't sure if these were the ones I added or if they could be babies. I can't get a better picture I apologize. If they are eggs of some sort any chance at seeing them hatch? Or notcing they have?

If so I was told they are nerite snail eggs.

Mine appear a little smaller and more sesame seed shaped. They are also not raised up too far off the rock.
