General Description
Drepanocladus aduncus, commonly known as Kneiff's Hook-moss, is an aquatic moss found in bogs and distributed worldwide, particularly in Central Europe. It thrives on the edges of ponds, riverbanks, lakeshores, wetlands, and fens, often forming dark green cushions in shallow water. Its sickle-like shoots grow above water, with submerged shoots exhibiting upright growth. Under sufficient light, it branches profusely; otherwise, it appears less dense, easily resembling "Stringy Moss."
Aquarium Suitability
With a rating of "very easy" in terms of difficulty, D. aduncus is suitable for aquariums, particularly those with cold- or warm-water conditions. It is versatile and grows well in low-tech tanks with native plants, making it ideal for various tank setups. It can be bound to rocks or driftwood using fishing line and does not attach itself to the substrate. Under strong lighting and CO2 supplementation, it releases abundant oxygen bubbles, but if not securely attached, it may float. It can form a dense mat if allowed to grow at the water's surface.
Demands and Hardiness
See table for specific details. D. aduncus is known for thriving in colder temperatures and can tolerate a range of water parameters from carbon dioxide levels to light intensity. It is a fast grower and can become weedy under favorable conditions.
Aquascaping & Usage
In aquariums, D. aduncus can be utilized similarly to "Stringy Moss" but with a more robust and ramified appearance. Its distinctive sickle-like leaves and curved shoots set it apart, adding visual interest to the aquascape. It is suitable for midground or foreground placement, especially in nano tanks, groups, or as a spawning plant.
Propagation
Propagation of D. aduncus is achieved through splitting and cutting off daughter plants, making it easy to multiply for aquarium or garden pond settings.
Habitat and Distribution
This species thrives in a variety of aquatic habitats, including ponds, riverbanks, lakeshores, wetlands, and fens. D. aduncus is commonly found in Central Europe but has a global distribution.
