I would hatch them in a separate tank and sell them on Aquabids. Is your snail a mystery snail? Congrats if so you got a female xD. I know a lot of people who go for mystery snails over some other breeds since they are more colorful and can be breed for some very cool shades like magenta.
Do you have a pic of your apple snail? Who knows, she might have been fertilized by a colorful male.
I think their eggs need to hatch out of water though.. contact @silverfang @tikibirds and @djembekah (possibly others) because I know for a fact these three have hatched snails.
