Pyramid snail or baby cerith snail?

[Mike N]

I have about 6 adult cerith snails in the tank. I've seen a couple of these tiny white snails that are shaped like ceriths. However, they also look like they could be pyramid snails.

What do you think?

I don't think they're pyrams.

Did you add a cuc recently? Can you maybe pull a couple out for a picture? I'm wondering if they're rissoids.

Great news!

The only think I added was the cerith snails, everthing else hitched a ride. I only see the one so far. I'll see if I can get a better picture when I get back to my office.

I think you're right about the Rissoid. It does seem to match the coloration and texture of the shell.
Thanks again.

@Lionfish Lair This guy has been riding on a cerith snail for a couple days now. Just want to make sure its a rissoid and not something else:

If you stick a couple between some duct tape, throw it in an envelope and mail it to me, I'll be able to tell for sure.
