You may think that, but with Piranhas, 6 months is like if you had them for a week, they take a whole lot of patience for them to act normal.
pirahna are over rated.

I've never seen a pack of them do enough decent damage to make me think anything great. Some might like them but I know a certain pair of R. Dev./Trimac, male and female that when breeding, don't care how big would certainly pummel them before any disembowlment occured. Those two made me bleed plenty of times when I would do something as silly and quick as move a rock....not to mention cleaning the tank. They weren't even bother by nets trying to catch them, that was just something else to tare up for them. They were a healthy 8 in. plus though 
That's what I heard.eL ChiNo LoCo said:

eer..
anyway..
They had a shoal of 'em and it took over a year for their P's to even eat durring day light hours in front of them. After that, they where more active and agressive then ever.
spawning pairs of cichlids, centrarchids, and other mid-sized nest guarders.
When not in breeding mode, there ain't any. There really isn't any one specie of fish out there that's guaranteed to be mean. Alot of people like to say the Asian Redtailed Catfish (http://www.fishbase.org/Summary/SpeciesSummary.cfm?genusname=Hemibagrus&speciesname=nemurus) is the worst, and I've heard plenty of morbid anecdotes in regards to them, but then I also hear reports of them getting beat down by regular old channel cats.
your question is frequently asked, and there really isn't a valid answer to it. You could always ask what the top 5 meanest fish are in YOUR EXPERIENCE.. but then that's hardly an absolute reference that anyone could use and expect to get reliable results from
jardini, dovii, smallmouth bass, undulated triggerfish, bowfin, red snakeheads, poecellids, green sunfish, trimacs, chipokae, H. fasciatus, beani, fahaka puffers, festae, damselfish... the list could go on a looong ways.
Do you know how many of the above fish I mentioned have an Undefeated record, out of all the accounts I've heard on all of them? None.
Some species of fish are definitely more aggressive than others, but when you're looking for the cream of the crop or whatnot, it depends on a given fish's individual personality, not the fish's specie
Alot of people regard the Texas cichlid to be a fairly unexceptional fish in the aggression department, and my own experiences correlate with this.
But then...
I don't know of any fish that would voraciously-- some would say suicidally-- attack a creature 100 times its own size.

you threw a dead piece of smelt in there and they ate it, I don't see what that proves, other than that they have impeccable jaws. Notice how the pleco looks fine and dandy and has probably been with them for months already, for example.
not to take anything away from you because you do sound like you know what your on about having owned some exellant fish. But Piranha's sould never be bought because of there reputation of aggression. I have a breading pair of piranhas and have had them for some time if you only have the one piranha it's end of story you shouldn't ever keep piranhas on ther own keep them in pairs or more they are social creatures if you have more than one and you dont feel they are acting as they should be try getting a bigger tank as piranhas can get very depressed that maybe a reason why they are not acting aggressive as you would put it. Also should your fish be depressed (let's hope they ain't) make two water changes a week doing water changes stimulates the fish and hopefully it may perk them back up again. I hope you find the answers to your problem and if you didn't allready know what i have told you i hope it helps.
