After you have watched the video above come back here and post what you would put in this tank. Freshwater only since it is salt in the video. Would you do thousands of community fish or monsters? This is what I'd do.
20 Airapaima
20 Black Pacu
15 Red Tailed Catfish
50 Fire Eels
30 ID Sharks
30 Arowana(different species)
5 Plecos
10 Datnoids
15 Oscars
20 Peacock Bass
40 Fresh water sting rays of different species.
10 Clown Knife fish
100 Silver Dollars
50 Bala Sharks
100 Angels
10 BGK
And there are probably others I can't think off.
