you have three options basically
1) ceiling. Never looks that great to just have everything hanging from the ceiling unless you maybe have the "hood" go from the top of the tank all the way up to the ceiling, making the tank seem more of a pillar.
2) An encasement stand. Something that supports the tank, as well as having bookshelves or something similiar along the sides, like spinman suggested
3) drilling the bottom of the tank and putting a tube from the bottom of the tank to the top to pass plumbing and electrical from underneath. IMO
, this is the "neatest" option. It will make your tank appear to be a free standing and disconnected tank. with a good hood on top to enclose everything, you will only see the stand, tank and hood in the middle of the room.
