I have the opposite problem. I wish I could get my snails to reproduce! I feed them to my puffer and try to get them to breed in my other tanks but they wont.

My water must be way too clean!
My Apple Snails usually wont breed in the main tank. Either they are hypersensitive to water quality or they don't get enough food or they don't like getting nipped at. They hide in the shell and only eat enough to stay alive. Doing the deed leaves them exposed to attack.
And while they can adapt and survive to some level of salt, they do not like it.
I breed them in a 10 gal with no salt and a variety of food. Spinach, lettuce, duck weed. Any vegetable that is soft enough. Sometimes potato or cooked carrots and peas.
As long as they like the water and don't have to hide from predators and have food, they are very active. They grow fast and are always hooking up and making babies. Females lay eggs in batches of hundreds every few weeks. Less in winter more in spring.
Also they do not need heated water but if it is too cool their metabolism slows down. While this causes them to live longer, they don't do much.
My little snail tank is sitting in a window. They are active but don't live long enough to grow out to max size. Mine are more like Ping Pong Ball snails, if that. I have never had a giant.
And a separate tank will allow you to use very hard water (I toss in all my used egg shells, chicken that is) and feed calcium rich foods (spinach)so they can grow their shell faster than it dissolves.
A bucket with space above water for eggs and a lid to keep them in and foam/air filter in a warm place would do.
This all would apply to "wet" layers and live asexual breeders. But if they lay eggs under water you might remove those for hatching before they are eaten. As well as small live birthed babies as those may also be eaten by adults.
As always survival comes before breeding. Make life easy for them.
