I recently added an elegance coral to my reef thinking it was a hardy species ... for the first two weeks this coral was beautiful,expanding even more fully than when I first saw it.Now it has become withdrawn with short stubby tentacles.After much research I learn that APPARENTLY this is common lately,some people believe that they are being collected deeper / farther out and some people say it is a bacteria that should be cured by dipping the coral in antibiotics.Lemme know what you think .
