In the new aquarium room and more specifically in my 360 gallon tank I have decided to put my Black Arowana with a school of Payara. I think it is going to be wicked. Their are a couple of Oscars, a school of Red Hooks, and some larger catfish in the tank as well. When the bigger 500-700 tank I'm working towards happens I'm going to add one or two more Black Arowanas or maybe one or two high shine Silver Arowanas. Or one of each. Anyways what do you think about a Black Arowana and a school of Payara?
