Bundle of Hornwort (Ceratophyllum demersum)

Hornwort, scientifically known as Ceratophyllum demersum, is a fast-growing, free-floating aquatic plant found in freshwater environments around the world. It is characterized by its long, dark green, feathery stems covered in whorls of needle-like leaves that resemble horns—hence the name “Hornwort.”

This plant does not develop true roots; instead, it absorbs nutrients directly from the water through its stems and leaves, which makes it an excellent natural filter. It floats freely or can be anchored in the substrate, and it provides excellent cover for fish and fry, as well as a spawning surface for egg-laying species.

Hornwort is incredibly hardy and adaptable, tolerating a wide range of water conditions and temperatures. Its rapid growth helps prevent algae blooms by outcompeting them for nutrients, making it a popular choice for aquariums, ponds, and water gardens.

Low-maintenance and highly beneficial, Hornwort is ideal for both beginners and experienced aquarists looking to enhance the health and balance of their aquatic ecosystems.
