Fish Crazy
I would definitely put some rays and other large exotic fish - then I would call myself an aquarium and charge admission (all fees going to the huge maintenance costs, of course )
maybe 10x altum angels
200x congo tetras
200x dwarf neon rainbows
200x rummy nose tetra's
200x cories
handful of nice fancy plecs
Sounds cool! Though, I would also heavilly plant it; loads of bogwood! Make it into an Amazonian Biotope (though, you'll have to ditch the rainbows and Congos!)
im quite surprised how many ppl would stick with small fish in a huge tank like this! each to there own i suppose
