    Description
    Hornwort (Ceratophyllum demersum) is a highly versatile and exceptionally fast-growing aquatic plant, making it an essential addition to beginner aquariums, breeding tanks, and coldwater ponds. Known for its fluffy, needle-like green foliage, this resilient plant thrives across a vast array of water conditions.
    One of the greatest benefits of Hornwort is its powerful natural filtration. As a rapid grower, it aggressively absorbs excess nutrients such as nitrates and ammonia directly from the water column, effectively outcompeting nuisance algae. It also acts as a fantastic oxygenator, releasing vital oxygen to support fish and beneficial bacteria.
    The dense, feathery structure provides a perfect natural refuge, creating a safe haven for shrimp, livebearer fry, and shy fish species to hide from predators or use as a spawning site.
    Hornwort is remarkably forgiving and easy to care for. As a rootless plant, it can be left to float freely at the water surface for shade, or gently anchored into the substrate to create a lush background bush. Regular pruning will help maintain its shape and encourage fresh lateral shoots.
    Important Care Notes:

    Hornwort is a true aquatic plant that grows exclusively underwater. It is normal for the plant to shed some needles when first introduced to a new environment as it acclimates to your water parameters. Simply remove any dropped needles and allow the plant time to settle — it will quickly bounce back with vigorous new growth.
