coral is one of the most popular corals and favorite of many reef keepers
all over the world. The xenia form stalks as it grow. The amount of
pulsing will vary with various water parameters but in known that it is
good indicator to its health; .In a healthy xenia, each polyp will "pulse"
meaning, open and close while in a failing xenia the polyps are frozen.

keepers regarding the pulsing action of the xenia coral. Some think
that it is for the filter feeding and some think it is related to oxygen

a small part of its original tissue behind to start a new colony.
