Common name: row pore rope sponge

General information

The Row Pore Rope Sponge, Aplysina cauliformis, is a fascinating marine sponge species known for its unique rope-like branches and vibrant coloration, which can range from yellow to purple. This sponge is not only a visually striking addition to the reef aquarium but also plays a role in the natural filtration of the tank's water by processing dissolved organic matter.

Care

Caring for Aplysina cauliformis requires a well-established aquarium with stable water conditions. It thrives in moderate to strong water flow, which facilitates its feeding process. Lighting should be moderate as well, mimicking its natural habitat in the reef environment. It's important to note that sponges should never be exposed to air, as trapped air bubbles can be fatal.

Reproduction

Reproduction in Aplysina cauliformis is both sexual and asexual. Sexual reproduction occurs through the release of gametes into the water column, while asexual reproduction happens through budding. In the aquarium, asexual reproduction is more common, allowing hobbyists to propagate the sponge by carefully cutting a piece of it and attaching it to a rock or another surface in the tank.

Symbiosis

While Aplysina cauliformis does not have the same type of symbiotic relationships as corals or anemones with fish, it does host a variety of microorganisms within its tissues. These microorganisms, including bacteria and cyanobacteria, are thought to contribute to the sponge's nutrition and defense mechanisms.

Habitat

In the wild, Aplysina cauliformis is typically found in the Caribbean Sea and the Gulf of Mexico, where it inhabits coral reefs and adjacent habitats. It often grows in areas with strong currents, which provide a steady supply of planktonic food.
