Common name: Red Sponge

General information

The Red Sponge, scientifically known as Spirastrella cunctatrix, is a species of marine sponge found in various reef environments. This sponge is recognized for its vibrant red to maroon coloration and its irregular, encrusting growth form that can add a splash of color and texture to the reef aquarium.

Care

Red Sponges are filter feeders and require a well-established aquarium with stable water conditions and moderate to strong water flow to thrive. They absorb nutrients directly from the water column, so maintaining high water quality is essential. It's important to note that sponges should never be exposed to air, as trapped air bubbles can be fatal.

Reproduction

Sponges like Spirastrella cunctatrix reproduce both sexually and asexually. In the aquarium, they often propagate through budding, where a part of the sponge breaks off and grows into a new individual. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other sponges.

Symbiosis

While not hosting symbiotic relationships as complex as those seen in corals and anemones, sponges can still play a role in the reef ecosystem by providing microhabitats for various small organisms and contributing to the overall biodiversity.

Habitat

Spirastrella cunctatrix is typically found in shallow waters of tropical and subtropical regions, often in shaded areas or under overhangs where it can avoid direct sunlight while still receiving adequate water flow for feeding.
