Common name: Gelidium Seaweed

Gelidium is a genus of red algae commonly found in marine environments around the world. It is known for its stiff, cartilaginous texture, which makes it an excellent candidate for refugiums in reef aquariums. Gelidium species help with nutrient export by absorbing excess nitrates and phosphates, and they provide a natural food source for herbivorous fish and invertebrates. This genus also plays a role in the natural habitat by contributing to the structure of algal beds, which offer shelter and breeding grounds for various marine organisms.
