I live in a tropical country, and snakeheads are legal here, but since they're banned in the U.S. I don't know where else to buy. So I want to buy a fish which is similar to your stereotypical snakead - breathes air, voracious appetite, quick breeder e.t.c. I'd like a fish with those characterists. As well as those above, I'd like the fish to: -Be decently priced. -Have sharp teeth. -Be aggressive -Grow to about 2 feet long or more. Any fish come to mind?
