I ordered a blue birdsnest frag which was delivered 3 weeks ago. It was a muave purple color skeleton with a half inch bleached white stem from shipping. The other stems are not bleached. I've had it in the tank for 3 weeks but have seen no PE. The bleach part has minimal improvement in color. The vendor already gave credit for the frag. Is there any chance this frag may recover? The skeletal base and branches are still muave colored and there has been no more obvious bleached death signs. I have about 20 SPS frags now that all seem to be growing with nice color. Just wondering if it is worth trying still with this birdsnest frag?
