I was looking for info on rams horn snails and ran into this thread. I didn't find much as for what I was looking for but wanted to let everyone know my experience with the mystery snails. They do lay their eggs above water level but if you ever have a entire egg sack survive you will have so many of them that you be giving them away so if your object is to keep snail population down get rid of all the egg sacks you find. One or two of these snails are cute as pets but it's not so cute when you have like sixty of them
