snail reproduction?

[Just5398]

How big or old can a snail be before it can reproduce? Apples, ponds or ramshorn specifically.

apple species reach sexual maturity at about dime sized (1 inch)I believe. Ponds and common rams reproduce readily from a very small size, not sure on the specifics. I notice ramshorn (common) eggs in my tanks when they are just larger than pea sized.
