How small are sundial snails?

[mcfa2403]

I just noticed several small snails in my tank. I have tried taking pictures but the pictures just aren't turning out. Each snail is about 1mm in length and appears to have a circular flat shell. I have yet to notice any zoas missing but I am now worried.

Sundials are pretty small but they have a very defined pattern on their shell. When in doubt, just pull them out. You can dip your zoas and take a close look at them if you are worried.

Yeah, you can ID thim with that little appendage they call a rattlesnake tail which you can see in MikeandNicole' s link above.

They aren't sundials as far as I can tell. Thanks for the help. I will probably go ahead and do a coral dip to be safe. They were mostly just hanging out on the LR. I can't seem to find what they are and they only come out in the dark.

Could be colonista snails. Mine only come out at night and kind of have a stripped pattern on their shells and they are pretty small. I have no idea where mine came from there were none and then one day there they were.

google collonista snail & see if that's it.

You don't need to dip the zoas if the snails aren't on them.
