Süsswassertang (Lomariopsis lineata)

Süsswassertang is a unique and highly popular freshwater fern-like plant prized for its soft, bright green, branching structure. Despite its name, it is not a true moss or algae, but a rare fern gametophyte that thrives in a wide range of aquarium conditions.

Its loose, flowing growth makes it ideal for shrimp tanks, breeding setups, and natural-style aquascapes. Süsswassertang can be left free-floating, attached to hardscape, or gently tucked into crevices, where it will naturally anchor itself over time.

Exceptionally hardy and undemanding, this plant grows well in low light and does not require CO₂, making it perfect for beginners and low-tech aquariums.
