Ive had these 2 pieces of over a year now and they are starting to bleach. I dont know if its beacuse, i came down to the tank this morning and my turbo snail knocked all the rocks over causing the 2 corals to be flipped upside down for who knows how long over then night; or is it the fact that i moved them up higher in the tank to quick? All my parameters are fine as well. But i do have one question ive had a tiny temperature swing which, does anyone think could cause this problem? All my other SPS and other corals are perfect where they are and show no signs of bleaching....does anyone know the answer to help me out beacuse im stumped....:bounce2:
