Hornwort Live Aquarium Plant - Ceratophyllum Demersum Floating Oxygenating for Fish Tank & Pond

Hornwort (Ceratophyllum demersum) is a versatile, fast-growing aquatic plant that floats freely in the water, making it an excellent choice for both freshwater aquariums and outdoor ponds. Its feathery, dark green foliage provides a natural, lush appearance while offering valuable cover for fish fry and small aquatic life. As a floating oxygenating plant, hornwort helps improve water quality by absorbing excess nutrients and releasing oxygen during the day.

Whether you're setting up a new tank or adding to an established pond, hornwort is an easy-to-grow plant that requires no substrate. It can be left floating or gently anchored, and it adapts well to a range of water conditions. Its rapid growth helps control algae by competing for nutrients, making it a practical and attractive addition to any aquatic environment.

Planting & Care

Hornwort does not require planting in substrate; simply float it in the aquarium or pond. If you prefer to anchor it, you can tie it to a small rock or driftwood, but avoid burying the stems. It thrives in a wide range of water conditions and benefits from moderate lighting. Regular pruning helps control its rapid growth and keeps it from shading other plants.

Maintain clean water and avoid extreme temperatures. Hornwort can absorb nutrients directly from the water column, so no additional fertilizers are typically needed. It may shed needles if water parameters change suddenly, but it usually recovers quickly. Remove any dead or decaying portions to keep the plant healthy and prevent water quality issues.
