I have I believe what is an Anthelia coral in a tank that I have adopted. It was doing really well and thriving and growing and spreading. It all of the sudden seems to be withering and dieing and falling apart. We've had a few cold snaps after a heating elemen malfunction, but that's since been stabilized. The chemical levels appear to be good. I'm doing a water change tonight as I missed my usual one last weekend to see if that helps. But would there be any other reason that I should look into what's happening???
