Hornwort

Hornwort (Ceratophyllum demersum) is a species of submerged aquatic plant that is native to North America, Europe, and Asia.

It has a unique appearance, with long, branching stems that are covered in tiny, needle-like leaves. The leaves are arranged in whorls around the stem and give the plant a bushy appearance.

The plant is a popular choice for aquariums and ponds because it is easy to care for and helps to oxygenate the water. It is also used in natural water filtration systems to remove excess nutrients and pollutants from the water.

Hornwort can tolerate a wide range of water conditions, from acidic to alkaline and from soft to hard water. It prefers bright light but can also grow in partial shade.

Because of its ability to quickly grow and absorb excess nutrients from the water, Hornwort is sometimes considered a nuisance species in natural water bodies and is regulated in some areas.
