Chestnut Turban snails are amoung the hardiest of the "turbo" snails. We collect these wonderful snails from the tropical waters around the Florida Keys. They will consume filamentous algae, green slime and diatoms. These snails vary in size from the size of a BB to about the size of a marble. They will get as large as a large marble. They are young and growing, so they will eat a ton of algae. This is the best time to get these snails.
