Amen to that! And it's really hard to hold a miniscule snail with
fingers, tweezers, or anything else I've tried. I can't trap them with
food, the fish would get rid of it first. I can't use chemicals because
of the live plants. And I don't have room for a loach.

I wonder if there's something you can dip in the water safely that's
sticky?
