They aren't tubifex, those aren't thick and dorsoventrally flattened like in that second pic. This is some species of freshwater ribbon worm. Easiest way to get rid of them is to just remove them yourself when you see them unfortunately, even if not incredibly effective. Not much info out there...
They do indeed feed on snails. Ramshorns are among their favs too. They are great parents, carrying the young on their bellies, so you can potentially end up with quite a few.
