The The loss of 50 gallons and almost half the height is not worth an extra 6 inches in width. I'm guessing that the tank was a frag grow out tank were the depth isn't needed.
Wide, but I am a ray guy and love wide tanks, they are super nice for large fish but with an arrow you need some height, Bass and arrow both need space. But a 220 works as well, its wide enough, if it was 72x30x24 that would be perfect, For your fish the bass and arrow the taller tank will probably be better. Arrow at top, bass middle to bottom mixed to top. So stay with what you have unless you can have BOTH !!
Thanks for the advice guys. I think I'm just going to stick with my 220. Once I eventually get my Arowana and Bass I think the extra height will benefit more than 6" more of width as you guys said. And besides, the 220 is just a grow out until I build my pond or purchase a large stock tank.
