I have a tort frag that turned a beautiful, deep purple color and had great polyp extension for about 3 months. And then it started to bleach very suddenly over a couple of days. I put the coral in a shady area and some reddish color seemed to return. I couldn't tell if it was algae or true actual re-coloration of the flesh. When I look at the frag up close with a magnifying glass, I still see the striations I'm used to seeing on the flesh of an acro. Does that mean the flesh is still there? Or will those striations remain even on dead skeleton? I'm trying to figure out if I should give up on this frag or not.
