I would definitely take off gars and pbass off the list. They are only preditory. Isn't this the same w/ African tigerfish?
It is hard to say what is most aggressive when I don't have experience w/ a lot of fish on the list. My experience w/ cichlids is that they are usually only aggressive w/ other cichlids as that would be thier main cometion.
African cichlids are supposed to be very aggressive and I am surprised no one has mentioned them.
I've seen videos of dorados and common wolfs and they would get my votes.
Another I'd like to add are c
Chinese algae eaters. They can be really nasty when full grown and males will ram other fish w/ their horns and suck on the sides of other fish.
 
The most aggressive fish I have ever kept is my 15 inch male dovii. He is in a 200 gallon alone @ 8 inches he ripped his mates upper lip competely off. If you get within 5 feet of his tank he slams the glass and splashes water across the room. He also splashes water when he wants attention he is definately the smartest cichlid I have ever had. His son who is now about 6 inches is just like him just with a little different color cause his mom is gold and dad is blue.

Are we doing predatory/aggressive or just aggressiveness? Most of the fish we are naming are more predatory then aggressive but still some what aggressive. Where do we draw the line between predatory and aggressive? Seems like a pretty blur line.
