I purchased a couple mystery snails a yellow shelled and blue from petco. They had a clutch of babies that are amber shelled and blue footed. I have a few of them left. Now my white snail is having yellow shelled white foot snails on its own. There is also some eggs waiting to hatch. I can do 3 babie snails for a dollar. The more you buy the better the deals. They will grow as big as a silver dollar coin. They are usually $3.99 or more at the store. The golden, blue foot are a mix of my two snails.
