Cerith Snail Eggs

[BigA]

I woke up this morning to a mass of zigzagging eggs on one of the side panels of my aquarium. Through some research, I have determined that my cerith snails have laid eggs. What are the chances that they will hatch and survive? Is this a fairly good indication that my tank is progressing along well? Is it possible to raise the snail eggs and have a breeding population?

This is not my tank, but is exactly what my eggs look like too
