Heck yeah those are some awesome fish. I had an Argentae male get to 13 inches and the colors were gorgeous. He claimed an 80 gallon all to himself and would not let me keep anything in with him. Mean fish but beutiful. I sold him like a fool then tried to buy him back but the dude said no way. Hartwegi is a lot less agressive and sport some pretty colors. Get a Veija Zonatus if you could find one their colors are incredible. They too are tough guys though.
