yeah they do. Only 25% of the people that start out with small arowana’s actually grow them to the size I have. Bobby La duke can tell you about it. He is a manager at eddies and my arowana is the biggest he has ever seen.
I also have a few red tail catfish, a few tiger shovel nose cats and a few marble sailfin cat’s. All these fish require 700+ gallons to live like they should which Im going to build a 700 gallon pond in my house basement sometime this year. I have already wrote the plans for it and such.
