Are snail populations self-limiting

First, Happy Father's Day to the dads out there.

Now on to my question. I got some plants from and pond snails hitched a ride on my formerly snail-free tank. At first I tried to find all of them and remove them, but I gave up on that. I don't want to use chemicals because they will kill the shrimp, which my kids love. I figured I would get assassin snails or loaches at some point.

My daughter has really started to enjoy the snails. I stopped crushing them/removing them as an experiment. My fear is that the population would explode. With no preditors, I figured that eventually their numbers would reach an intolerable level, but that doesn't seem to have happened. It seems pretty steady.

Do snails "know when to stop" reproducing? If so, that males me feel much better.

If you put loaches in the tank they will eat your shrimp as well.

to controle my snails i use anatome helena (killersnales).
In my opinion you also can control it by reducing the amound of food.

(crushing them and feeding them to shrimps is a win-win situation)

The snail population will go through cycles. When food is abundant they'll multiply like crazy and eventually that will lead to higher competition for resources causes many of,them to die off.
