its very tolerable to different levels of light. compared to my reef tank i would say its under medium light right now. for flow i would recommend low to medium, direct current may cause it to tear. if nutrients get too low its may not fluoresce as much, this is it under 0pmm phosphate ( my limiting nutrient), and between 3 and 7 ppm nitrate. so you can see that you would have to have extremely low nitrate to lose color.

also if its in really low light it will dim a little bit, but even the frag in the back corner of my tank ( pretty low light) is still orange and fluorescing.
