you should put the tank where you want it.
Putting the tank in a high traffic area just because its a high traffic area is bad resoning. Some fish are extremly sensitive to stress and having such fish in a high traffic area with people walking by all the time with room lights going on/off all the time, etc can cause undue stress on the system.
About a year ago a member whom I dont think is active any more had problems with is fish and disease after many months of no problems at all. What he figured out was all his health issues started very soon after his wife started doing some inhome daycare. The extra noise/activity of the kids in the house and specificly in the room with the tank where stressing the fish.
