As much as I love Discus and Angelfish, you can't, can't beat a nicely planted tank with large schools of Tetras and Rasboras in it. With that sized aquarium, you could also go area specific and get schools of fish from a particular part of the world ( say Amazon, Asia, Australia, etc) and put a collection of assorted fish from that area that won't eat each other. Just an idea
With that size, you could also make a dynamite Saltwater tank as I did in a pet store I worked in. We used large pieces of corals and rocks to make the tank look like the edge of a reef on one side (where all the reef dwellers stayed) and there was plenty of room for the schooling fish (such as tangs and Moorish Idols) which they enjoyed using. It was a nice comparison tank to see what fish used what type of cover to stay in.
Just some thoughts...
