Xenia turning white and losing stalks

My Xenia frag is turning white and losing stalks...what could be causing this? Disease, stress....? It has been in my tank for over a month with no problems until the past couple of days.

I would just watch it. As long as nothing in your tank has changed it should be ok. I have a few spots in my tank where pulsating xenia grows and I have had this happen every once in a while, usally when one of my levels goes out of wack. They close up, turn white and look like little bumps on the rock then start growing again. These things are like weeds!!!
