Common name: Hymedesmiidae Sponges

Hymedesmiidae is a family of sponges within the order Poecilosclerida. These sponges are known for their encrusting growth forms and can be found in a variety of marine environments. They often display a range of colors and can add a unique aesthetic to a reef aquarium. Hymedesmiidae sponges are filter feeders, playing a role in nutrient cycling by consuming dissolved organic matter and bacteria. They require stable water conditions and moderate to strong water flow to thrive in captivity. It's important to ensure they are not smothered by algae or outcompeted by faster-growing sessile organisms.
