Large bunch of Brazilian Pennywort, Hydrocotyle leucocephala. This easy to care for 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. It has flat, lilypad like leaves that will grow up and along the surface of your tank, and it can also be added to a tub pond, where it can grow over the edge of the container as a decorative "spiller" plant, while also serving to help oxygenate your pond and provide hiding places for fry.
