Sundial snail???

[Nick862]

I have got loads of these and They seem to be breeding rapidly, iv had a sundial snail before and these don't look like one, plus I never see them on corals, any one got a ID on these? One looks like it's attacking my turbo snail

yup. those look like sundials to me.
there is one in this "pot o gold" i got out of a zoa shipment from indo...see him?

Oh dear!! Thanks

 

[mr_X]

wait..they are not shaped like turbos...they are sort of flat. if those resemble turbo snails but are very tiny, they are not sundials, but collonista(sp?) snails, and are harmless.

They look like collonista, I don't know what it's doing to my bigger snail? I'll keep an eye on everything, added a few more picture of these snails. thanks for the reply, great help like always
