I got this pretty acan last weekend. The blue was really this blue! The blue has since turned greyish brown and the red is beginning to brown as well.
It is sitting on the sand bed with a par rating of about 200. I'm not sure what to do. Should I move it up for more light? Maybe less light? I have other areas of the sand bed with 160par (due to rock structure). I just don't know which way to move it.
My lighting is 2 x 250w 20k, with 2 blue+ t5s, and 2 purple plus t5s.
