Ask Finn

Brilliant scarlet-red, blade-shaped macroalgae — one of the most visually striking species for display refugia. Provides excellent colour contrast and nutrient export. More delicate than Chaeto; requires moderate flow and consistent light. Popular with collectors and stunning under reef lighting.
