About this item
Shaving Brush (Christmas Tree) Macroalgae
Shaving Brush macroalgae (Penicillus spp.) is a distinctive calcareous green macroalgae recognized for its single upright stalk topped with a dense brush-like crown of fine green filaments. This species grows from the substrate as an individual plant and adds a unique natural reef aesthetic to aquascapes.
Because of its unusual shape and vibrant coloration, Shaving Brush macroalgae is often used as a focal plant in reef aquariums and lagoon-style aquascapes.

Special Considerations
Shaving Brush macroalgae is a calcareous species that incorporates calcium carbonate into its structure. Because of this, the plant consumes both calcium and alkalinity as it grows. Maintaining stable reef chemistry supports healthier growth and long-term stability.
🌱 Propagation
Shaving Brush macroalgae is typically not propagated by cuttings like many other macroalgae. In aquariums, propagation is most often associated with sporulation or natural basal expansion over time.
- Not a frag/cutting species: trimming the “brush” or stalk usually does not create a new plant
- Sporulation (natural reproduction): mature plants may release reproductive cells in stable systems
- Basal growth: healthy specimens may slowly thicken or expand from the base under good conditions
- Best expectation: purchase as a complete plant rather than planning for fast propagation
