It depends on what type of snails you have.
the small snails which appear in tanks will not get much bigger then 1cm.
but if you have an apple snail or other store bought snails they can grow to be quite big.
i have an apple snail which is over 50mm by 50mm.
No.
BIG!
Some snails in Houston can grow to the size of a baseball.

Sea snails are pteropods and are an essential food for bowhead whales. These snails feed on phytoplankton and gather in big groups that discolor the water.
Freshwater snails typically grow to be around 1 to 2 inches in size.
For a giant African land snail it is 5-12 inches (WOW)
There is no parental care amongst snails. As soon as the eggs are laid the baby snails are on there own. Its really no big deal.
