| Care Description | Xenia are one of the few corals that have a constant pulsing motion. It makes them one of the most eye-catching corals in a reef tank. The purpose of their pulsing behavior is not well understood but the prevailing sentiment is the corals pulse to increase flow around the colony and maximize surface area for photosynthesis. Xenia are also one of the fastest growing soft corals making them a great coral for beginners on one hand but opening up the possibility of rapid infestation on the other. Despite their growth rate issues, they remain one of the most popular corals amongst reef aquarists in the hobby. Please see below for additional care tips for Xenia. |

General Description
Xenia corals, known for their constant pulsing motion, stand out in reef tanks due to their captivating behavior. This pulsing action, believed to enhance flow around the colony and maximize surface area for photosynthesis, adds to their allure. Xenia are rapid growers, making them appealing to beginners but potentially leading to quick infestation if not managed carefully, yet they remain highly favored among reef aquarists.
Demands and Hardiness (Setup)
Xenia, with their unique pulsing behavior, require careful consideration in tank placement to maintain their distinctive motion. As they feed on Phytoplankton and Zooplankton, liquid and powdery foods are crucial for their nutrition. These corals passively absorb dissolved organics from the water, relying significantly on their zooxanthellae for energy. To avoid overwhelming rockwork, thicker-stalked varieties like the Red Xenia are recommended. Providing low to high lighting is suitable, with acclimation suggested for corals introduced to intense lighting environments.
Lighting
Xenia demonstrate adaptability to various lighting conditions, making them versatile additions to reef tanks. Regulating light exposure, especially for corals initially placed in high-intensity lighting regions, is advised to facilitate proper adjustment and growth.
Water Flow
Maintaining low water movement is vital for Xenia corals, as their pulsing motion serves as a mechanism for water circulation. Excessive water flow can hinder their natural pulsing behavior, affecting their energy production sourced from zooxanthellae.
Feeding
Xenia's diet primarily consists of Phytoplankton and Zooplankton, necessitating the provision of appropriate liquid and powdery foods. These corals passively absorb nutrients from the water column and rely on products produced by zooxanthellae for sustenance.
Propagation
Xenia species, extensively propagated in captivity, present a promising opportunity for aquaculture endeavors. With ongoing efforts, sustainable harvesting practices can be achieved over time, contributing to the conservation and cultivation of these corals.
Localization & Habitat
Originating from the Indo-Pacific, Xenia species are native to islands such as Fiji, Tonga, the Solomon Islands, and the Great Barrier Reef. These corals thrive in specific regions of the Indo-Pacific, showcasing their natural habitat preferences.
