Sundial Snails?

[2ndThief]

I'm afraid I have an incredibly large amount of sundial snails.

I have probably 100 tiny tiny tiny white swirly shells on my rocks and they have arrived within the past few days and I dont know how, I always dip and I am also not sure that they are sundials, I have tried to get a picture and they are two tiny to get in focus on my camera so I do not know what to do, and if they are I do not know how to get rid of them aside from pick them one by one and if I do that then I will miss several because they are so many and so tiny. Please help, and thank you very much

The sundial snail will eat colonies of zoanthids. From your description, chances are that they are harmless snails. I have hundreds of what you're referring to. Small white snails that resemble tiny turbos. Unless they get larger and start to take on the yellow/black pattern, then I wouldn't be concerned.

They do sound like collonistas. Here's another pic from Melevs site. All of the Sundials I've seen/found were all stuck right in the zoanthids and not that numerous.

Ive had these sundials destroy some zoas but leave others alone.
Finally got rid of them
