Orange Acan turning green

[MDKMR2]

I have a really nice Orange Acan with dark orange (almost maroon) eyes that is slowly turning green. All the eyes however have remained that maroon color. Some days it seems more green than others so I hope it will not totally change over. Its been on the bottom of my 75 gal with the same T5 bulbs for over a year. The coral is very healthly so just wondering if anyone has has a similar experience and if they were able to prevent the color change. Ironically, I have another orange acan right next to it that has never changed for the past year?

I have one with orange mixed with green and if it is in too high of light the orange turns to green.

Well I would have said its reacting to light and raise it, but if miracles38 says his does the same in high light, then look for a cave or a shaded spot and see if the orange returns.

I guess I will try to find a shaded spot since its already on the sand. I had to the same with another red (rings of fire acan) when I switched to the T5s. It however just lost its bright red color from too much light which I think it more common with the red varieties. It did not change color gradually like this one is. Thanks

Too much light, put is in the shade somewhere.
