"Uh-oh, I think I might have AEFW..." I saw this statement several years ago. I wasn't too concerned, and thought it wasn't a big deal. Later, I discovered my favorite SPS coral was fading fast, the color literally leaving the coral more and more daily. Staring at the coral, nothing looked wrong with it other than it being faded. It was polyped out, and seemed to grow at the regular pace. Still, I was concerned.
