Contortion Vallisneria (Vallisneria tortifolia) is a species of aquatic plant that is commonly used in aquascaping. It is also known as Twisted Vallisneria, Corkscrew Vallisneria, or simply Contortion Val.
This plant is native to South Asia, including countries such as India, Sri Lanka, and Bangladesh. It typically grows in freshwater streams, rivers, and ponds, and can tolerate a wide range of water parameters.
Contortion Val has long, thin leaves that can grow up to 2-3 feet in length, and are only a few millimeters wide. The leaves are twisted and contorted, hence the name, and have a dark green coloration. The twisted leaves create a unique and visually striking appearance, making it a popular choice in aquascaping.
The plant is generally undemanding in terms of water parameters and can tolerate a wide range of temperatures between 60-82ﾡF (15-28ﾡC). It prefers moderately soft to hard water with a pH between 6.5 and 8.0, but can adapt to a variety of conditions.
Contortion Val is a rooted plant that is typically planted in the substrate of an aquarium. It can also be planted in sand or gravel substrates, as long as it has enough nutrients and light to thrive. The plant propagates through runners, which are horizontal stems that produce new shoots and roots.
When grown under ideal conditions, Contortion Val can grow quite quickly and form dense stands in the aquarium. It is best suited for larger aquariums with plenty of space to accommodate its size, and can be used as a background or midground plant.
Overall, Contortion Vallisneria is a visually striking and easy-to-care-for aquatic plant that can add a unique touch to any aquascape. Its twisted leaves and undemanding nature make it a great choice for both novice and experienced aquascapers alike.
