Could I add another arowana to my silver duo

A healthy tank would survive an hour long power outage.
 
The tank size determines it all!
 
What is the size of your current tank? Two silvers going to take a big space... and if you get another, it's going to need even more. Do you have that big space or are you intending to get that big needed space??
