Hornwort Live Aquarium Plant

Hornwort (Ceratophyllum demersum) – Fast-Growing Aquarium Plant

Hornwort is a hardy, fast-growing freshwater aquarium plant ideal for beginners and experienced aquarists alike. Its feathery, needle-like leaves provide excellent cover for fish and fry while helping control excess nutrients and algae in your tank.

Care and Growth

Hornwort is highly adaptable and can grow floating or planted in your aquarium substrate. It thrives in a wide range of water conditions, tolerating soft to hard water and acidic to alkaline pH. As a tropical plant, it prefers temperatures between 18–28°C (64–82°F).

Hornwort grows quickly and can help absorb excess nitrates, making it a natural tank cleaner and oxygenator. Regular trimming may be needed to keep it from overtaking your tank.
