i recently bought a Japanese Trapdoor Snail. later that day, i noticed a baby snail crawling about. i put him in a floating breeding trap. later the next day, i found another baby, and put him in as well. im wondering where did they come from? there were no eggs, and no signs of the snail giving birth (i dont know if trapdoor snails are live bearers or egg layers). did they hitch a rid? if so, how? they couldnt have been on his shell because i clean it repeatedly with my finger and they couldnt have come in the bag because i only pulled him out of the bag.
