All Glass Aquariums is one of the leading aquarium manufactuers around. In fact, they're so good, they're the only aquarium we carry at where I work. We've a few Oceanics in now and again, but those you're going to be spending a whole lot of money on.
If you can't find a tank already made to the specifications that you want, you may want to enlist the help of your local contractor, who may be able to put you in touch with a glass smith that could custom make it for you.
Hight does matter, because whe you think of the weight of water, you don't want your tank to become too top-heavy.
