I pulled my assassin snail out of one of my tanks today to put him in my little pond and I saw eggs, two maybe three, on his shell! How'd they get there? Maybe they're not eggs? He's not in with any other snails... I don't think. He hitched a ride on a piece of driftwood and almost got my mystery snails! Jerk. But it's not his fault, so I'm trying to do right by him, lol.
