Genus
Common name: Spongia
Scientific name: Spongia
Spongia is a genus of demosponges, commonly known as commercial sponges, found in warm sea waters. They are known for their high commercial value and have been harvested for bathing and cleaning purposes for centuries. In reef aquariums, they can serve as natural filtration systems, absorbing dissolved organic compounds. Spongia species typically have a tough, fibrous texture and require moderate to strong water flow and good water quality to thrive. They are filter feeders and need a supply of planktonic food. They are non-aggressive and can coexist with most reef inhabitants.
