Common name: Sargassum

The Sargassaceae family, commonly known as Sargassum or Gulfweed, includes marine brown algae that are often found floating in tropical and subtropical oceans. These algae form dense mats on the surface of the water, creating unique ecosystems. Sargassum is notable for its complex structure with leaf-like fronds, berry-like gas-filled bladders that aid in flotation, and small branches with reproductive structures. In the aquarium, Sargassum species can be used to create natural refugia, providing habitat for microfauna and a natural method for nutrient export. They require moderate lighting and water flow to thrive.
