Common name: Red Beard Sponge

Hymeniacidon is a genus of sea sponges known for their striking red coloration and beard-like growth patterns. These sponges are filter feeders, playing a crucial role in maintaining water quality by removing bacteria and organic particles. They are relatively hardy and can be a unique addition to a reef aquarium, adding both color and function. Hymeniacidon species typically thrive in moderate to strong water flow and require good lighting to support their symbiotic algae, which provide nutrients through photosynthesis.
