Clownfish eggs & snails

[cbm369]

Just a quick question;
I have a male/female Black Ice pair that I'm hoping to breed. I have put in a small flower pot, clowns have adopted it and looking after it. But I have a lot of snails that have taken a liking to the pot as well. Should I worry about them eating any clownfish eggs? Or keeping the clowns from laying?

thanks
