Christmas Moss
BeginnerVesicularia montagnei
A moss branching in triangle like Christmas tree. Creates more three-dimensional scape than regular moss.
Overview
Christmas Moss (Vesicularia montagnei) is a moss plant in the family Hypnaceae, native to tropical Asia. It takes its name from its branching growth habit, where branches extend in a triangular, drooping pattern resembling a Christmas tree. Its greater three-dimensionality compared to regular Java Moss creates beautifully natural scenery when attached to driftwood. Hardy enough to grow without CO2 under low to medium lighting, it is also ideal shelter for shrimp and fish fry. Increased lighting promotes denser growth, and CO2 addition further accelerates development. Attachment strength is comparable to Java Moss, and it is cultivated by securing it to driftwood or rocks with fishing line or adhesive. Maintaining its triangular silhouette through moderate trimming maximizes its aquascape impact.

CO2 & Fertilizer
Grows without CO2, but injection promotes growth further. It needs almost no fertiliser.
Water Temperature & Quality
A water temperature of 20-28°C is suitable. It provides shelter for shrimp and fry, so it is easy to grow in a tank with livestock.
Substrate & Attachment
Fix it to driftwood or rock with fishing line or glue and let it attach. Its attaching ability is about the same as Java moss.
Trimming & Propagation
Trim moderately to keep its triangular silhouette and it grows attractively. Re-tie the trimmed pieces to propagate it.
