Common name: Gracilaria

Gracilaria is a genus of red algae notable for its economic importance and its role in marine ecosystems. Hobbyists appreciate these algae for their ability to absorb excess nutrients, which helps control algae blooms and maintain water quality. Gracilaria species are also cultivated for their agar content. In the aquarium, they provide a natural food source for herbivorous fish and invertebrates, and their bushy, branching structures offer shelter and breeding grounds for small marine organisms.
