Hitchicker id help

[Mbodell]

I have two of these guys that I have seen now. They just started showing themselves recently. They are laying small white curly eggs all over that place. They are whitish blue. They seem to be grazing on the live rock and I haven't seen them on any corals yet. Should I try and hunt them down or leave them alone since they aren't really hurting anything. (that I can tell)

stomatella? blurry photo.... but i think...it is

After some googling, I think you are right. It did look like it had a shell and they seem to be grazing. The only thing I am unsure about is the white curly eggs. An article I found says they release them into the water, not onto things.

i've seen stomatella release egg clouds into my tank.... def not curly strands

I am starting to think the spirals might be spirorbid worms

Here's a couple of picks from last night, stomatella snail is correct, harmless and neat, I nicked named mine a rabbit, they can really move. I haven't seen mine for 6 months or better and last night it showed up riding on a another snail and at least 4 times bigger then the last time i saw it. Diversity is good in a tank.

The Reg snail is the one holding on the eggcrate with the red colors, the stomatella is the pinkish hitchhiker on its shell.

stomatella are technically not snail. i don't know how their geneology are broken down but cousins of snails but not really snail despite it having a shell on it's back.
