I've had this coral for about 9 months and its growth has been really good and color excellent. I've fragged it a couple of time with no ill effect. But in that last 2 days, 50% of the coral has bleached. The only change to the system is I added a copperband butterfly and one spot rabbitfish last Thursday. I have no issue with any other corals. There was an emerald crab living under the center ridge and even he has moved out. Maybe a coincidence? I don't know.
Params
Ca 420
dKH 10.9
Mg 1550
Sal 36 ppt
Nitrate 5
Phos .09
Temp 79
I've kept these parameters fairly stable for the past year. Any ideas?
