Which needs more light? Acro...milli.

i just bought a blue tort acro....a pink and blue milli.,and a green with blue tip milli.

should the tort be closer to the top..or does it matter?
 
What type of lighting do you have? Also, most acros need a lot of waterflow movement. If you have MH, you should be able to put the corals midrange to top.
