Pest snails (ponds and rams) are hermaphroditic, so they'll keep reproducing after mating once, even if another mate isn't available.
Mysteries, trapdoors, nerites, and assassins are specifically male or female, so you need one of each gender for them to reproduce. If I remember correctly, not even baby assassins are safe from adults.
Also, useless trivia, assassins are actually a freshwater whelks, not snails.
