For catfish experts out there. I'm curious what can actually be kept with large predatory catfish? Some people said peacock bass, arowana and etc. I don't know how true if that really works. I bet alligator gar is an obvious way-to-go choice since it's hardy and large enough to not be eaten by any large predatory catfish out there. And by large catfish, I'm talking about at least TSN's size and larger like piraiba or wels. The largest catfish I currently own is a RTC that I've kept for 3 years.
