Common name: Crambe Sponge

General information

The Crambe Sponge, scientifically known as Crambe crambe, is a species of marine sponge notable for its bright red to orange coloration and encrusting growth form. It is a member of the family Crambeidae and is found in the Mediterranean Sea and adjacent Atlantic areas. This sponge is not commonly kept in the home aquarium due to its specific requirements and slow growth rate, but it can be an interesting addition for advanced hobbyists seeking to create a biotope aquarium.

Care

Crambe crambe requires a stable, mature aquarium with excellent water quality. It thrives in low to moderate light conditions and prefers strong water movement to facilitate feeding on dissolved organic matter and plankton. This sponge is non-photosynthetic and relies on filtering water to obtain nutrients. It is sensitive to high nitrate and phosphate levels, so regular water changes and efficient filtration are essential.

Reproduction

Reproduction in Crambe crambe occurs both sexually and asexually. Sexual reproduction involves the release of gametes into the water column, while asexual reproduction can occur through budding or fragmentation. In the aquarium, asexual reproduction is more commonly observed.

Symbiosis

While Crambe crambe does not have notable symbiotic relationships like those seen in anemones or corals, it does contribute to the overall health of the reef ecosystem by filtering water and providing a surface for other organisms, such as certain types of microfauna, to inhabit.

Habitat

The natural habitat of the Crambe Sponge includes rocky substrates and overhangs in the Mediterranean Sea, typically at depths ranging from shallow waters to about 30 meters. It often grows in areas with strong currents which aid in its feeding process.
