Hornwort Aquatic Plant (Ceratophyllum demersum)
Hornwort is one of the hardiest and fastest-growing aquatic plants available, making it a favorite for beginners and experienced aquarists alike. Its soft, feathery green foliage creates a lush, natural appearance while providing excellent cover for fish, shrimp, and fry. Whether used as a floating plant or anchored in the substrate, Hornwort is highly effective at absorbing excess nutrients, improving water quality, and helping to reduce algae growth in freshwater aquariums.
Native to freshwater lakes, ponds, rivers, and streams throughout much of the world, Hornwort is an incredibly adaptable plant that thrives in a wide range of water conditions. It can be floated freely, where it forms dense mats near the surface, or loosely anchored in the substrate without burying the stem. Its rapid growth and versatility make it ideal for planted aquariums, breeding tanks, goldfish aquariums, and outdoor ponds.
Hornwort grows quickly under low to high lighting and does not require CO₂ supplementation. While it benefits from regular fertilization, it readily absorbs nutrients directly from the water column, making it an excellent natural filter. Frequent trimming helps maintain its shape and encourages healthy new growth.
This versatile plant pairs beautifully with Amazon Swords, Vallisneria, Anubias, Cryptocorynes, Java Fern, and a wide variety of other aquatic plants. Its dense foliage provides shelter for fry, shrimp, and timid fish while creating a natural spawning environment for many egg-laying species.
