Birdsnest bleached

[mike007]

I have two large colonies of birdsnest corals. They have been thriving for several months and now one of them has turned completly white like overnight. Water parameters are good and everything else is doing great. I am puzzled why it turned white so quickly. Has anyone have any ideas?

I took a frag from home and put it in my work tank. Great like crazy for a good about 7-8 weeks then one day just started bleaching like crazy. All other sps pieces are 100% and unfazed. My parameters are spot on too. Wish I had an answer. My piece was so bright pink and great polyp extension too.

Not from what i saw. Steady at 8. Everything else has been doing just fine, growing with polyps out each day

Samething happened to my pink milli and red planet. I didnt even have an alk swing. They turned white over night. No other sps were affected. I still dont know why.
