Common name: Gracilariales

Gracilariales is an order of red algae primarily found in marine environments. Members of this order, such as the well-known genus Gracilaria, are often used in reef aquariums for nutrient export and as a natural food source for herbivorous fish and invertebrates. These algae are valued for their ability to absorb excess nutrients like nitrates and phosphates, helping to maintain water quality. They come in various forms, from bushy tufts to flat, leaf-like structures, and can add a diverse range of textures and colors to an aquarium setup.
