Common name: Azure Vase Sponge

General Information

The Azure Vase Sponge, scientifically known as Callyspongia plicifera, is a visually striking species renowned for its vibrant blue to purple coloration and intricate vase-like structure. Found primarily in the Caribbean Sea, this sponge is a favorite among aquarists for its unique appearance and the aesthetic appeal it adds to marine aquariums.

While not as commonly kept as some other marine species, the Azure Vase Sponge is appreciated for its natural filtration capabilities, as it helps maintain water quality by filtering out small particles and organic matter. Its presence in an aquarium can be both a functional and decorative addition, offering a glimpse into the complex ecosystems of coral reefs.

Care

Caring for the Azure Vase Sponge requires attention to water quality and flow. These sponges thrive in well-established aquariums with stable water parameters. They prefer moderate to strong water flow, which helps them filter nutrients effectively. As they are sensitive to changes in water conditions, maintaining consistent salinity, temperature, and pH is crucial.

Azure Vase Sponges do not require direct feeding as they obtain nutrients by filtering plankton and organic particles from the water. However, ensuring a nutrient-rich environment will support their health and growth. Regular monitoring of water quality and avoiding the use of copper-based medications is important, as these can be harmful to sponges.

Reproduction

Reproduction in Callyspongia plicifera occurs both sexually and asexually. In sexual reproduction, the sponge releases sperm into the water column, which is then captured by other sponges, where internal fertilization takes place. Larvae are later released into the water and settle on a substrate to grow into new sponges. Asexual reproduction occurs through budding, where a small part of the sponge breaks off and grows into a new individual. In reef tanks, reproduction is rare and challenging, but a healthy sponge may occasionally produce new growths under ideal conditions.

Symbiosis

While not typically involved in symbiotic relationships like some other marine species, the Azure Vase Sponge can provide habitat and shelter for small marine organisms, such as shrimp and small fish. Its structure offers protection and a place for these creatures to hide from predators, contributing to the biodiversity of the aquarium.

Health and Common Issues

The Azure Vase Sponge can be sensitive to poor water quality and abrupt changes in tank conditions. Ensuring stable water parameters and avoiding exposure to air during water changes are key to maintaining their health. If a sponge becomes damaged or begins to deteriorate, it can release toxins into the water, which may affect other tank inhabitants.

To prevent health issues, maintain a regular schedule of water changes and monitor the sponge for signs of stress, such as color fading or tissue degradation. Promptly address any water quality issues to prevent further deterioration.

Habitat

Naturally, the Azure Vase Sponge is found in the warm waters of the Caribbean Sea, often inhabiting coral reefs and rocky substrates. They are typically found at depths ranging from 10 to 30 meters (30 to 100 feet), where they attach to solid surfaces and thrive in the nutrient-rich currents of their environment.
