My black aro out-grew [IMO] its 5'x2'x2' in just over two years. It went from 6" to 24" (was just touching front to back) on a diet of mainly pellets and some meaty food (no feeders!). I think you'd want something AT LEAST 3' wide for it to be comfortable for life. 6'x3'x2' would be the bare minimum IMO, and an 8'+ would be better.
Just remember they're not lazy like a 2' snakehead or something, they like to swim, and can swim fast too! I cam home late/drunk one night and flicked the light on, the poor fish panicked and hit either end of the tank half a dozen times in a matter of seconds!!
