i keep my z's & p's in the bottom 1/3 of the tank but use strong lights, that picture is in a 34 cube with a 250w halide (i can grow many species of SPS on the floor of that tank as well. The fruitloops are now under LEDs in a different tank and getting a lot more actinic lighting than previously and they are really taking off, starting to grow on the underside of the plug (getting little to no light). As long as they are getting the appropriate amount of par.
