A 500g? Cool, 8'x3' footprint? Now you need to decide if you want a mixed origin tank or one that everything comes from the same area. You can go as big as arowanas or stick with several very nice midsized (12-18") predators, Also do you like beefy fish or narrow bodied. If you answer these questions I will have a better idea of the kind of mix of fishes you might enjoy. In a mixed origin tank you might consider an arowana, a mottled eel (Anguilla marmotus), a lima catfish, a red snook (Petinia splendida), a pike cichlid of some kind, and 3 tinfoil barbs as dithers, or a golden perch (macquaria ambigua). Only the last would be hard to find.
