I got this as a 3/4 sized frag grew for one year to 2 1/2 inches. All of a sudden it started bleaching all other corals are doing great. And I never moved it since day one in the tank until it started to bleach so I moved it to my 72 gal. Some eyes are still green but 85% bleached. Levels of ammonia nitrite and nitrate are zero and calc at 400, phosphates are good as well
