What are these?

[Wanda65]

Any idea as to what these are? Good/not so good? Found them in this “empty “ shell on the sand bed. Seem like snail. Thanks

Maybe a species of pyramid snail? Idk though, the shell shape doesn't look correct based on your picture. Have a Google for "pyramid snail reef tank" and see what you think.

 

[Wanda65]

Thanks for that idea, but they don’t have that shape. They are more rounded on the ends.

Pictures are blurry, but many baby snails look like that. Those could be baby nassarius snails or likely many others.

If they are in the water or on the glass you may be able to identify them easier, they’re all retracted there. Maybe put them in a small container with tank water and take more pictures.

 

[Wanda65]

Thanks. I’ve never seen them on the glass. I’ll keep looking and try for better pictures

I found a bunch of these feasting on a snail that was on the sand bed, so I scooped them up. They can actually move fairly quick. Any ideas, or where I should l look?
Hope you all are weathering the storm ok!

I still can't tell because you've got them out of the water, but they seem to have a siphone and shell shape consistent with nassarius snails. Behaviorally, if you saw a group of them scavenging a dead snail, that also matches up.

If you can get a picture of them on the glass/sandbed there will likely be easier to confirm the anatomy.

Looks like some species of marginella or olive snail to me by the shape hard to tell

You can send the pics to John at reef cleaners and he’s usually quick to ID them for you

Thanks for your responses. They are so small I don’t think I can get a picture of them on the sand bed. Glad that no one is saying they are some super bad critter. I’ll keep at it. Happy reefing!

I second olive snail.
