How do Mystery, Apple and Ramshorn Snails reproduce? I kno MTS are livebearing, but do they need another snail to fertilize them? In other words, which snails are asexual?

the mystery/apple snails need both male and female to reproduce. they will lay eggs just like the ramshorn/pest/pond snails. well, not *just* like them, but they all lay eggs of some sort

So if you only have 1 of any snail, you wont get any offspring?

if you have only one apple or mystery snail, you will never have baby snails, and probably only rarely see any eggs. the ramshorn/pest snails, on the other hand, will reproduce like crazy without another snail around.

apple/mystery snails need 2 snails to reproduce generally male and female but there are a few rare cases of certain applesnail species changing their gender. Most of these snails lay eggs above the water line so even if you have 2 just scrape the eggs off. There is also the giant ramshorn which is an applesnail and needs 2 snails to reproduce but lays it's eggs underwater. Also known as Marisas. You might get eggs from a female applesnail but without a male they won't hatch so remove them before they rot. If your water is all the way to the top even with a male and female you probably won't get any eggs(except marisas). The small ramshorns(non applesnails) and various pest snails lay their eggs underwater and 1 can equal 100 quite quickly.

Hi, some of the apple snails will hold their eggs for some time so if you just got one it is possible for it to lay eggs even though a male is not currently in the tank with it. I use this site as a reference alot.
