Common name: Ircinia Sponge

Ircinia is a genus of sponges found in various marine environments, known for their tough, fibrous texture and potential to produce bioactive compounds. In reef aquariums, they can serve as natural filtration systems, absorbing dissolved organic compounds and providing habitat for beneficial microorganisms. Ircinia species often display a range of colors from dark brown to greenish hues, adding a unique aesthetic to the tank. They require moderate water flow and some feeding with dissolved organic matter, but are generally low-maintenance.
