Neurymenia fraxinifolia

Neurymenia fraxinifolia (Saw Blade)
Known as “Saw Blade,” this striking red macroalgae features long, serrated fronds with a crisp, rigid texture that sets it apart from softer macros. Its bold structure makes it a standout for aquascaping, adding dramatic texture and movement to planted marine tanks. While not as palatable to herbivores as some other species, it still contributes to nutrient export and a balanced ecosystem.
