About this item

Scarlet Serrata Macroalgae

Scarlet Serrata Macroalgae (Neurymenia sp.) is a rare and visually extraordinary Australian red macroalgae that brings something genuinely different to the reef aquascape. Its defining feature is immediately unmistakable — broad, flat fronds edged with dramatically serrated, jagged margins in a vivid scarlet red that fans outward in an open, architectural structure from a single rock base. Under reef lighting, the intense red-orange tones glow with a depth and richness that makes it one of the most visually arresting macroalgae you can place in a display tank.

Unlike the dense or bushy growth habits of more common red macroalgae, Scarlet Serrata grows in an open, upright fan — each individual frond clearly defined and separated, creating layered visual depth and texture that photographs beautifully and commands attention in person. The serrated frond edges catch flow and light in a way that adds constant subtle movement to the display without the algae ever becoming unruly.

Sourced from Australian waters, this species is rarely seen in the hobby outside of specialist collections — making it a genuine conversation piece and a standout addition to any serious macroalgae or reef display system.

Special Considerations

Scarlet Serrata performs best in stable, established systems with consistent water parameters and moderate flow. Avoid strong direct flow which can damage the delicate frond margins over time. Keep away from aggressive herbivores including urchins and large tangs that may graze on the fronds. As with all display macroalgae, handle gently during placement to avoid tearing the fronds at their base.
