I currently an a bit over the top with the fish thing.
I maintain 500 gallons in 7 tanks.

A few notes.

the cheapest way to do it is to build your own stand and canopy for a 55 gallon tank, then  light it with a 4 foot shop light from the hardware store.  This gives you a sleek 4 foot tank that doesn't protrude into the room and enough light to grow real plants.  The stands you can buy are usually either over priced, clunky or both so I suggest you build your own.  Plywood & paint work extremely well just make sure that you follow one of the designs online.

Other things: spray paint the back of the tank a solid color (black works really well, but any dark color that will match your decor works) and use a decomposed granite or aquatic plant soil on the bottom instead of expensive aquarium gravel.  It looks better, plants grow better and it saves you 70-95% of the cost.

lastly, use a canister filter that you can hide underneath the tank and a black submersible heater to keep all the unsightly cables and tubes at bay.
