My week old elegance coral is closing up and not opening open to ideas? I got it March 22nd and it was doing fine but then it started to slowly degrading.
Elegance Coral, Catalaphyllia jardinei, is a LPS that is very beautiful easy and is one of my favorite LPS. Since early 2000, it was well known by reefers that Elegance coral is easy to care for, unless it contracted Elegance Coral Syndrome (ECS), a universally fatal disease with no known cure...
Sorry to hear you lost it. For future reference, that doesn't look like ECS IMO. I've only seen pale colouration and retracted flesh like that when the coral is getting too much light. I've been ramping my lights for over a year now and my elegance still kicks off every so often. I dial the lights back a few percent and it's out again a few days later.
