I had a 32" Arowana..in only a 240 gallon tank about 30 years ago now. This man is doing what I wished I could have done,give it a proper sized aquarium. I stand up and applaud him. I think the South American Arowana as the king of Aquarium fish..sure the Asian has got it beat on color,but the S.A. just hypnotizes you with grace and some do have reddish edged scales. Mine did.
