Ceratophyllum demersum (Hornwort)

Hornwort, also known as Coontail, has sturdy, layered hair-like foliage that helps oxygenate and clarify the water as well as keep algae growth to a minimum. It is found free-floating worldwide, in moving and still waters, or loosely anchored in muddy bottoms.

Hornwort leaves are dark green and grow from a 1/2 to 1-1/2 inches long on stems that can reach 24 inches in length. They may be potted or just left to float in the aquarium.
