Genus
Common name: Hymedesmia Sponges
Scientific name: Hymedesmia
Hymedesmia is a genus of sponges in the family Hymedesmiidae, known for their encrusting growth form and ability to blend into their surroundings. They are filter feeders, drawing water through their porous bodies to extract nutrients. In reef aquariums, they can serve as natural water cleaners and provide a unique aesthetic. They are non-aggressive and can coexist with a variety of tank mates. Hymedesmia species typically require moderate to strong water flow and good water quality to thrive.
