i hate it when anything shrivels up -- especially when it's a coral frag I procured from a well-known public aquarium. The xenia I've had since this fall have been shriveling up and dying, one colony at a time. My largest (and last) colony is on it's way out. I had hoped that better flow and lights and more religious water changes and dosing various good stuff would help, but no dice. The xenia shrivels and the main stalk becomes white and bumpy-looking in texture. Any ideas of what's going on and how I can fix it?
All of the other corals and critters in the tank are doing just fine, thank goodness.
