General information

Xenia elongata, commonly known as Pulsing Xenia, is a species of soft coral highly sought after by reef aquarium hobbyists for its unique pulsing behavior. This coral is characterized by its elongated polyps and the rhythmic, pulsating movement of its tentacles, which resembles a gentle pumping or waving motion. This movement is not only mesmerizing but also aids in the circulation of water and nutrients across the coral's surface.

Care

Pulsing Xenia is considered one of the easier corals to keep, making it a good choice for beginners. It thrives in moderate lighting and water flow conditions. While it can obtain nutrients through photosynthesis, supplemental feeding with fine particulate foods can promote growth and health. It is known for its rapid growth rate and can quickly spread across rockwork, so it's important to manage its placement to prevent it from overgrowing other corals.

Symbiosis

While Xenia elongata does not have any specific symbiotic relationships like those seen in clownfish and anemones, its pulsing action can benefit neighboring corals by enhancing water flow and nutrient distribution in the aquarium.

Habitat

Xenia elongata is found in the Indo-Pacific region, typically in shallow, sheltered reefs with moderate water movement. It often forms dense colonies that can cover large areas, providing a dynamic and attractive display in both natural and artificial reef environments.
