Common name: Axinella Polypoides

General information

Axinella Polypoides, commonly known as the Branching Sponge, is a species of sponge found in the Mediterranean Sea. It is known for its distinctive tree-like structure and yellow to orange coloration. This sponge is not commonly kept in home aquariums but can be an interesting addition for advanced hobbyists looking to diversify their reef tank with non-coral invertebrates.

Care

Caring for Axinella Polypoides requires a well-established aquarium with stable water conditions. They are filter feeders and need a constant supply of planktonic food to thrive. Good water flow is essential to deliver food and remove waste. They do not tolerate high nitrate or phosphate levels well, so efficient filtration and regular water changes are crucial.

Reproduction

Axinella Polypoides reproduces both sexually and asexually. Sexual reproduction occurs through the release of gametes into the water column, while asexual reproduction happens through budding or fragmentation. In the aquarium, asexual reproduction is more common, allowing the sponge to slowly spread over rocks and surfaces.

Habitat

In the wild, Axinella Polypoides is typically found on rocky substrates and overhangs in the Mediterranean Sea, often at depths ranging from 10 to 40 meters. They prefer areas with moderate to strong currents which facilitate their filter-feeding lifestyle.
