Common name: Rough Sponge

General information

The Rough Sponge, scientifically known as Axinella verrucosa, is a species of marine sponge found in various parts of the world's oceans. This sponge is characterized by its rough texture and branching, tree-like structure. It exhibits a range of colors, typically yellow to orange, and can add a unique aesthetic to any reef aquarium.

Care

Caring for Axinella verrucosa requires a well-established aquarium with stable water conditions. It thrives in moderate to strong water flow, which facilitates feeding as it filters microorganisms and organic particles from the water. Adequate lighting is also necessary, although Axinella verrucosa is not as light-dependent as photosynthetic corals. Regular water changes and maintaining proper nutrient levels are crucial for the health of this sponge.

Reproduction

Reproduction in Axinella verrucosa can occur both sexually and asexually. Sexual reproduction involves the release of gametes into the water column, where fertilization occurs. Asexually, it can reproduce through budding, where a part of the sponge breaks off and develops into a new individual. In the aquarium, asexual reproduction is more commonly observed.

Symbiosis

While Axinella verrucosa does not have the same type of symbiotic relationships as some corals and anemones, it does play a role in the reef ecosystem by providing microhabitats for various small organisms. Its structure offers shelter and a surface for other invertebrates and microfauna to settle and thrive.

Habitat

In the wild, Axinella verrucosa is typically found on rocky substrates, reef slopes, and overhangs in the ocean. It can be found at various depths, often ranging from shallow waters to deeper regions of the reef. This adaptability makes it a versatile species for different types of saltwater aquarium setups.
