Stomatella snails - or maybe something different?

[kyley]

Hi All,
I've long been a fan of Stomatella snails, but I have a small zoa colony that's been closed up lately. I picked it up and found these guys huddled up under it. Are they something different? Harming my zoas?

Thanks,
--Kyle

Not the cause of your zoa issues. You look correct in your id. Have any pics of the zoas?
