I've had my 6 ivory mystery snails for about a month now. I'm assuming they are now comfortable because the males have constanly been breeding. I'm sure I at least have 2 breeding pairs. They've been mating 1-2 times a day for the past 5 days. When should the females lay eggs after mating? In a week? In a a few days? I've heard they can store up sperm for weeks...but what's the average gestation period? Thanks.
