Willow Moss
BeginnerFontinalis antipyretica
Epiphytic moss that attaches to driftwood and rocks. Perfect shrimp shelter. No CO2 needed, beginner-friendly.
About
Willow moss is a collective trade name for aquatic mosses — the name originally belongs to Fontinalis antipyretica, and species such as Taxiphyllum are also sold under it — that attach to driftwood, rocks, and other hard surfaces in the aquarium. Their soft, branching fronds sway gracefully in water currents, creating a naturalistic atmosphere that is central to Nature Aquarium and biotope layouts alike. Attachment is achieved by tying with fishing line; the moss adheres firmly within one to two months. It grows well under low to moderate light without CO2 supplementation, although CO2 injection encourages denser, more lush growth. The intricate structure provides excellent cover for breeding shrimp and fry, increasing its popularity in community tanks. Regular trimming of older portions maintains a tidy, attractive appearance.

Water Temperature & Quality
Aim for 20–28°C. It serves as a breeding site for shrimp and a refuge for fry, so it is easy to manage in community tanks.
Substrate & Attachment
Wrap it onto driftwood or rock with fishing line and it attaches within one to two months. Do not plant it in the substrate.
Trimming & Propagation

Cautions
Algae tangles in it easily, so prevent it with water changes and cut back overly thick parts to keep water flowing through.
