Small but deadly, the freshwater puffer. In order of aggressivness:
Freshwater puffer
Oscar
Betta

And at the top of that list will be an odo when i get it!!!!!! :D :D :D :D

If you like those guys just wait until you leave the non-aggressive section!
 
my recent tourmenter is my clown trigger... picking on clownfish...
 
My Amphilophus Chancho male. He has killed numerous fish in the 220 gallon tank he is in. I came home one day and found he had bitten part of his mates head off! He is by far the most aggressive CA cichlid I've kept, and I've kept them all!

My Chuco Micropthalmus is still my most aggressive fish by far. He's been housed alone for several years now and I will probably never house him with any other cichlid. At this point he's way to rare for me to risk having anything happen to him not that it would anyway lol.
 
This guy...

hands down i think its the dovii male. my 12" dovii was too aggressive. i put an oscar and a red tail catfish in a black bag to hold them. i placed the bag in the dovii tank to maintain water temperature. i stepped out to the store and when i came back the hole was ripped open and both fishes were torn in pieces... =(
 
my 4" red devil, at this size and all alone in a 55g he is bashs his head on the glass if i get 2' from his tank and then if i touch the side of the tank he goes crazy.
