Common name: branching sponge

General information

The Mediterranean Sponge, Axinella dissimilis, is a species of sponge found primarily in the Mediterranean Sea. It is known for its branching structure and yellow to orange coloration, which adds a vibrant touch to any reef aquarium. This sponge is a filter feeder, drawing in water to extract nutrients, and is an excellent indicator of water quality in the tank.

Care

Mediterranean Sponges require a well-established aquarium with stable water conditions. They thrive in areas with moderate to strong water flow, which facilitates their filter-feeding behavior. It is crucial to maintain high water quality, as sponges are sensitive to elevated levels of nitrates and pollutants. They do not require additional feeding if the water contains enough dissolved organic matter.

Reproduction

Reproduction in Axinella dissimilis occurs both sexually and asexually. In the aquarium, asexual reproduction is more common, with the sponge growing new branches from its base. Sexual reproduction involves the release of gametes into the water column, but this is less likely to occur in a home aquarium setting.

Symbiosis

While not known for any specific symbiotic relationships, sponges like Axinella dissimilis play a crucial role in the ecosystem by providing microhabitats for a variety of small organisms and contributing to the overall biodiversity of the reef.

Habitat

Mediterranean Sponges are typically found in rocky substrates and on the walls of caves at various depths in the Mediterranean Sea. They can adapt to different light conditions but do not require direct lighting in the aquarium, making them versatile for placement in different areas of the tank.
