Pulse Xenia Coral

The Pumping Xenia Coral, are also known as 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
