Where should I place my returns? - Arowana

Depends on how big a sump you want to use. I would place the returns so that the top of your water level is just above the top of of your return outlet. That way you minimise backflow going back to the sump from the tank when the pump is off. Also this will create surface agitation of the water for oxygenation. Why two returns ? are you using two pumps?
I think your design looks like a big space waster especially in a 3' wide tank.
Why have the returns plumbed in on the inside of the tanks ?
If you like that design, why not do it on the back of the tank where it will look much more tidy and less intrusive.

this was designed to be in the middle of the room as a room divider. i want to be able to walk around and see the other side and minimizing seeing all the piping. the sides where the overflows are will be covered with the same type of wood as the stand and canopy.
i put two returns because i figure it would have a better even flow. I also figured the water flow will not be so pressurized like a garden hose and nozzle. is it not necessary or not recommended? I think I will be running only one pump but was thinking of splitting it and using some valves to adjust the pressure on each side.

That design takes away 12" of a 72" tank. Doing this, you now have a tank that is too small to sustain the arowana in the long run !
I have an idea that will gain you back your 12" and still be able to have as a room divider.
Can you run piping on the outside of the tank in the same position as you have in the drawing ? Can you spare 6" on one side externally ?.

I agree,
6 foot is awfully short swim space for a 30"+ black aro and your cutting out a foot of that. So basically the tank will only be twice as long as the aro when it matures. Really should shoot for at least a tank length 3 times the length of the aro as a minimum.
i get exactly what your thinking. that would be great but the area that im temporary putting cannot exceed 72". it would block the bedroom door. it's either lose 12" of space or not be able to see through the tank. temporary but long term until we move it to my parents house years from now.
if i move the overflow to the back i would lose only 6" of the 36". which is better, two overflows at the back corner or one long one at the back?
anybody tried to plumb under the tank? maybe have the return and drain on the bottom with no overflows.

put the overflow in the center, or in 1 corner, it doesnt have to be ginourmous just enough to let the flow in. I bet a 4x4" will be PLENTY
Only way I can see by having the return on the bottom and be maintenance and headache free, would be to plumb a single 1" return from the bottom though a bulkhead and 1" pipe running directly up towards the surface where you would just put a 90 degree bend or similar so that flows across the surface of the water. Inlet would be a single 1 1/4"-1.5" standpipe which would draw form the surface. (sizes I used for the pipes are minimum as not to create bottleneck for the volume of water you have and flow) You can enclose them like your drawing or have them open in the tank. If I had to do it this way i would put them in the centre on one side of the tank next to each other so as not to obstuct viewing.
Put one overflow box in the middle of the tank. Here's a picture from Midwest Custom Aquariums gallery:
