Kenya Tree Coral problem

[weemanpow3]

All of a sudden my Kenya Tree Coral has closed up for 2 days and its all scrunched up and wont open. Its been in the same spot for 2 months and its been spreading very fast. I looked for anything that was eating it and still nothing. My water peramitors are right on and its about 4 inches all around when its open.

Please help me.

It could be just having an off day. But in the chance that is not the case, how old are your lights , what are their sizes watts k rating , (sometimes a coral Will crash for no reason by living off their reserves) What are your perameters numbers please . Check spg . Was there anything that may have been sprayed in or around the tank ? Just for added measure you may wish to add some carbon and do a water change ...what are the tanks inhabitints ? That may offer up some clues if something is picking on it or irritating it , any other corals close by that could be irritating it ?
