Aside from everything already said in this thread...native fish take up more water and in my experience are pretty boring. They aren't usually very colorful and normally don't do much besides find a place to hang out and stay there....until it's time to eat. Then they come out, get food and go back to their spot. I've kept small catfish, bass, bluegill, crappie, etc...all the same. About the most amusing I've seen them was when I temporarily house a couple of bluegill for a few days in a tank on my back deck and that was probably only because the tank was empty and there was nothing for them to hide behind.
Good post but they are what he likes.
