how long does it take to lay the snails?

Answer 1

I'm not sure I understand your question. Are you asking how long it takes snails to lay eggs? In apple snails it can be done in a few hours to a few days, depending on how many eggs are laid in each clutch. A female can store sperm from one mating and can continue to produce fertile eggs for several months. Eggs can hatch in 1-2 weeks, depending on the temperature.

Not all snails are egg layers though. The Malaysian trumpet snails give live birth.
