To be honest, I think the tank itself is awesome but could be more interestingly decorated and could have more interesting fish. Pacu and iridescent sharks are just so...available at Wal-mart. It's cool to see fish that really need that much space get exactly what they need, but I definitely think it would be much, much cooler to have a huge mixed community. Schools of hundreds of black neons, cardinals, danios of all sorts...hatchet fish schools up at the surface, huge shoals of cories and loaches along the bottom. Heck, I bet if you put a big enough lunker in there, say a 4 ft arowana, it wouldn't really even bother with something as small as a neon and even if it did, well, you've got hundreds more! The baltimore aquarium has tanks of similar size, both marine and freshwater, where huge schools of tiny fish are kept with massive lunkers. One big marine display had tons of cardinals, neon gobies, surgeons, wrasses, clowns, everything you'd expect to see in a big reef display, plus about a 5 foot grouper. So I just *know* something like that is possible for freshwater.
