Nitella Flexilis Aquatic Pond Plant – Stonewort

Nitella flexilis, commonly known as Flexible Hornwort, is a freshwater plant species that belongs to the Characeae family. Here is a detailed description and care guide for Nitella flexilis:

Description:

Nitella flexilis is an aquatic plant that is typically found in slow-moving or stagnant freshwater habitats such as ponds, lakes, and streams. It has a unique appearance with long, flexible, and branching stems. The stems can grow up to 60 cm (24 inches) in length and are covered in fine, thread-like branches. The plant is dark green in colour, and the branches have a delicate and feathery appearance. Nitella flexilis is a submerged plant, and it doesn’t have true roots. Instead, it anchors itself to the substrate using rhizoids.

Care Guide:

Lighting: Nitella flexilis can tolerate a wide range of lighting conditions.
It can thrive in low to moderate light levels. If grown in an aquarium, provide 1-2 watts per gallon of full-spectrum light for optimal growth.

Water Parameters: Maintain a water temperature between 15-25C (59-77F). The pH level should be slightly acidic to neutral, ranging from 6.0-7.5. Nitella flexilis can tolerate a wide range of water hardness.

Substrate and Anchoring: Nitella flexilis can be anchored to the substrate or allowed to float freely in the water. If anchoring to the substrate, use a fine-grained substrate like sand or gravel. Ensure that the substrate is not too compact, as it can impede the growth of the plant.

Nutrient Requirements: Nitella flexilis can absorb nutrients directly from the water column but can benefit from supplemental fertilization. Regularly add a liquid fertilizer or root tabs rich in macro and micronutrients to support its growth.

Water Flow and Oxygenation:
Provide moderate water flow to prevent stagnation and promote oxygenation. This can be achieved through the use of a gentle water pump or by positioning the plant near the filter outlet.

Propagation: Nitella flexilis can propagate vegetatively through fragmentation. Simply divide healthy portions of the plant and replant them in the desired areas. Over time, new shoots will grow from the fragments, establishing new plants.

Compatibility:
Nitella flexilis is a versatile plant that can be used in various aquarium setups. It provides shelter and grazing areas for small fish and invertebrates. It can also serve as a nutrient absorber, helping to maintain water quality. Overall, Nitella flexilis (Flexible Hornwort) is a visually appealing and easy-to-care-for aquatic plant. It adds a natural and lush look to freshwater aquariums while providing additional benefits such as oxygenation and nutrient absorption. With proper care and suitable water conditions, Nitella flexilis can thrive and enhance the overall aesthetics of your aquatic environment.
