The Red Sea Pulsing Xenia are also known as Pumping Xenia Coral, Pulse Coral, or Waving Hand Corals. They are colonial animals with multiple individual polyps attached to a piece of solid substrate. They form stalks as they grow, and to reproduce. The eight-tentacled polyps can pump, or pulse, and many scientists believe the pumping action of the polyps slowly opening and closing is designed to dispose of gasses and waste. However, it is still unknown why these coral do pulse, and there are many water, lighting and nutrient factors involved. It is not necessarily a sign of ill health if they do cease to pulse.
Aquacultured Xenia are hardier than wild-caught species and tend to reproduce quickly. Therefore, provide adequate space between them and sessile animals, especially other types of soft corals. They require a low to moderate light level combined with a medium to strong water movement within the aquarium. For continued good health, they will require the addition of iodine and other trace elements to the water.
They contain the symbiotic algae zooxanthellae from which they receive the majority of their nutritional requirements. Additional weekly feedings of micro-plankton or foods designed for filter feeding invertebrates are also needed.
This coral will come attached to a rock, shell or frag plug.
