The chocolate fish is a confectionery from New Zealand, dating back to at least 1966.They are fish-shaped, 5 to 8 inches in length, and are made of pink or white marshmallow covered in a thin layer of milk chocolate with the ripples or (scales) on the fish created simply by the fish moving under a blower; this slides the unset chocolate back, creating the illusion of scales on the fish. Several companies make the fish, but the most well recognised is Cadbury.
