I guess a vampire tetra would fall into this category then. basically peaceful until hungry - and then i've heard stories of it slaughtering fish twice it's size.

Yeah it can happen. with alot of fish..
but if you were to take any fish, put them in a 240g tank with a divider in the middle.. let them acclimate for a few days, then remove the divider.. Who would win?
Only Cichlids and Channa have the mindset and mentality to instantly wage war.. puffers, characins, sharks are all passive predatory.. not even territorial.
I have to say wild caught male doviis are,they have that territoral lifestyle,and killing instinct.I read a article where a guy said he was collecting fry scuba diving and was attacked by one.
This is and always will be an interesting debate as fish vary, but for me and my experience, (I repeat my expericence 
) I would have to say the cichlids because of there territorial nature. Fish like the Dovii or Umbee due to the shear size not to mention bad attitudes. They are the pitbulls and rotwielliers of the fish world. I have have owned wolf fish (not really territorial but man when its dinner time look out, a true beast), pirahna (only red bellies though, skiddish and boring until feeding time) and giant snakeheads (can live well with other fish unless they can fit in their mouth). I hate to say it but when I moved to a larger house many years ago, I had to put a bunch of fish together (not proud of this ) and my 18in snakehead killed two of my (wifes) 8in pirahna's, and eat them up to the head. I think she is still mad about this to this day. lol So I moved him to a 125gal holding tank with a 12in butterkofri and a 14in dovii and within a few hours of trying to get things moved, the dovii had taken plugs out of him, almost left him dead. There is something about a fish that will attack the largest fish in the tank to get rid of him. That's what makes fish like the Dovii and Umbees I think the meanest. In fact with Umbee your lucky if you can house a female with a male sometimes. And lastly , many year ago after trying to breed Umbee's, I bought a proven breeding pair from a guy that had two pairs. The male was around 16 and the female was around 12in. Brought them home to a 300 gallon that was divided with a mating pair of dovii's, male about 13in female about 8in. Things were fine for about three day, but then the males starting attacking the divider and eventually made way to get to each other. Thank God I was home as a fight started with the males. Now I actually let them go at it for at least 5min just out of curisoty. What I noticed was though the umbee was much thicker and longer than the dovii and would drive him back if they locked, the dovii was presistant at attacking the umbee. Even when it looked as if the umbee wanted to stop the dovii was running rampant trying to get at him. After I seperated them again, the umbee didn't show much aggression at the divider but the dovii was still acting like a rabid dog or something. So again I think there is one thing to be a nipper like a puffer fish, or eat agressive like the wolf fish or snakeheads, but to attack the largest fish just becsaue says something in itself.
