Placement of aquarium?

prefer to put a aquarium in the living room, its a rectangular shape living room with gates on south east direction sofa is placed on the south and south west of the living room where the fridge is on the north west of the living room basically the NORTH side of the plot of land is 32 degree towards east. just from entrance of the right side is a TV unit ie. east of the living room on the north east there is a opening for dining area. Now we are planing for the aquarium to be placed on south west the corner side of the sofa ie the space from south sofa and west sofa sitting arrangement. kindly advice. is it also possible to put a triangular aquarium
