Large bunch of Hornwort, Ceratophyllum demersum, at least 5 10" stems. This easy to care for, attractive, fast growing plant can be grown like a stem plant or it can be left as a floating plant. Great nitrate remover, as it grows quickly as is easy to harvest. Great for shrimp and fry tanks! It can also be added to a tub pond, serving to help oxygenate your pond and provide hiding places for fry.
