I have an amazingly healthy tank of ornamental rams horn snails. We have red foot and blue foot, pink, blue, leopard and many variations. We feed minerals and supplements, none have cracks or shell blemishes. They are very pretty. Help keep the tank clean, by cleaning up over feeding of fish, and algae clean up. Come and get 10-15 for your aquarium, your choice of colors for $5 or if you want to use them for feed, 1/4 cup full of little ones, no color choice for $10
