These are apple snail eggs, but dried up, because they were too far from the water. If the eggs aren't any good they are white. If they are pink then they are ok and will hach. When it first happend for me 7 years ago I freaked, and untill few years ago I never got small baby snails, what i made was, make a glass cover 2 inch(5cm) above the water, and since then milions :duh: .
