well my xenia has been slowly dying off, colonies falling off daily. I dont know why and have been trying to research why but everyone has the same problem and no real solutions. I have it high with moderate flow. Its a pulsing xenia. everything else in my tank is doing great, i dont want to lose it. Any ideas, Someone posted earlier on another form saying theve been known to die for no reason. Then i was told it was a great beginner coral.
