sundial snails or look alike?

[smallreef]

I have many snails that reproduced at a very quick amount, now there are hundred+. they are very small and come out only at night. They have the similar patterns as sundial snail however they dont have that strange pointy thing on the bottom. They have a regular flat area that closes when they close up.

Are there snails that are similiar to the sundials that arent harmful?

Sounds like it, I have a bunch of those, good algae eaters

I did a search, they are exactly what you had said, I thought they were sundials because some of my zoos are detaching from the rocks but they are definately not.

Thanks

Do you have any pics? I found a sundial (I think)yesterday on a frag of my zoos, I fed him to my fish only tanks.
