Considering your 46 bowfront is a pretty awesome planted tank, why not go ahead and do a hardscape (no plants and a lot of wood and rocks) with some bigger, more imposing fish in the 55. If it's where I think it is (right behind your dinnertable), some larger cichlids (chiefly the Geophagus types due to their peaceful nature), silver dollars, and clown loaches would look pretty cool.
