i think backgrounds are totally down to where the tank is situated. me mate has no background on his, but is been put between two desks in his spare room so you can see it either side you sit on. all the plants and rocks are well positioned too, so you dont feel like there is a certain side to sit.
On my tank, i do have a background. its only a deepish blue, so nothing special, but it helps the fish stand out more. that, and the wall behind it is manky! lol
it's also placed in the bedroom too. opposite side to the bed so it cant be heard when the heater comes on. really nice atmosphere too when the main light in the room isnt on, and its only the tank light on.
i think ures looks pretty cool just where it is. just hope you dont knock it over if the bed is in use? lol
your tank could use a background
