Snail ID - with picture

[francis]

Hi so these small guys started showing up lately. I have been trying to remove them every time I see them but they keep coming. Oddly enough they are usually in pairs like this one (some aren't though)

Can someone ID them so I can do some research on them?

Looks like a royal gramma to me?

probably collonista snails. why are you trying to remove them?
