Thanks a lot to all of you
The stand was chosen because I don't really like how the usual aquarium stands looks. So I picked up an old piece of furniture and converted that into something useful. The guy I bought it from told me that it had been his great grand dads, and he himself was no young man, so I figure it must be at least 100 years old.
@Smatter: The tank is just a regular tank, where I glued in a box in one of the bottom ends, making it into a drop. I then glued on a frame on the bottom, so that the room under the shelf is "invisible".
