Piranhas. They don't get any more aggressive than that.
Or you could get some sharks with frickin' lasers attached to their heads.

Piranha, Pacu and Oscars are all out of the question for a 29 gallon tank, they all get way too large. Besides, Pacu and Piranha are not aggressive. You need a fish that doesn't get over about 6" tops for a tank that size. Sticking 2 aggressive fish in a tank that small is only going to result in fighting until one dies.
If you want one aggressive fish to put in there go for a 2 spot pike cichlid. They don't get too big but are aggressive and only eat other fish, which make them pretty cool to watch at feeding time.

A male beta fish. Often called Siamese fighting fish, or at least that's what I've heard them called by a lot of people. Put two males together and they will fight to the death.............Put a male and a female together, and I think they will mate then fight, but I've only ever tried putting two males together.........As for putting two aggressive fish in a 29 gallon aquarium, I'll say that if you like fights then put a male beta in it with any other fish, because the betas will try to kill anything. But betas are almost too aggressive to share a tank, and a 29 gallon is too big for just one. I don't know a whole heck of a lot about fish, but I've had a few fish before and there is one fish that I've only seen once in an exotic specialty pet shop that would be perfect. But I hardly even remember what it looked like, let alone what it's called.....

Get a tank full of Bucktooth tetras, they are super mean and nasty.
I would not get a pacu or an oscars in anything less than a 75g tank. I speak from experience, a nasty salesman as at pet store years ago sold me 3 fish, 2 2" oscars and a pacu the same size. I was 10, and happy to have those neat fish and put them in a 35g tank they quickly outgrew. They also ate most of the other fish I had.

I am just guessing, but many people when they say aggressive they are referring to their feeding behavior.
Assuming this I would say cichlids. I have a Red Devil that I recently moved from my 75 gallon to a 30 gallon because he was chasing everything - nipping fins and quite literally trying to eat any fish smaller than him! He voraciously attacks the feeder fish swallowing them whole. It is really neat to watch, but often I feel really bad...
I agree with the other posts, it is really not fun to have a tank with an aggressive fish picking on everything else. Slowly but surely, the bully will kill the others and bring disease along as well. I enjoy my red devil more now that he is alone in his tank.
There are also a number of other cichlids that would be great, some get big like my devil while others stay small and are like dynamite in small packages.

ya want an aggressive fish? I bred tropical brachisk and fresh water fish over 20 yrs. Pacus, are aggressive. they attack everything, I had a magueneses of equal size and they ate it in half in one bite. They look and act like piranas cuz they are kissing cousins of them. One can fool the typical person that they are and teach people to keep hands out of tank. they have hard visible teeth, and spash half the 50 gal tank out in no time. They grow big and fast. Make a meal in no time lol. Though they are tetra family, the act like the pirana of south america. GL Keep hands out
also an electric cat fish is another real shocker for ya, some people have died from shocks, also lion fish of salt water, fins are deadly poisonous. Rock fish is too for salties.

chichlids and bettas are quite eggresive.
although with bettas u can only have 1 male by himself
it is best not to have tank mates with the males as they may attack other fish. but what u can do is either get a 20g tank with a bunch of female bettas they would still be aggresive so u would need to add alot of caves and plants if u try this get 6 or more to lower the fighting.
i dont know that much about chichlids but i do know u will need alot of them so they dont try and start staking out territories. if u choose bettas u can go to a betta forum for alot of answers you will neeed.....ultimatebettas.com is a great forumthey have alot of information on bettas and other fish too!!!!
im not sure but i think fighting bettas is ilegal in the us
as they can and most likely kill each other.

When you have fish, it won't matter if they're aggressive or not, because they won't be aggressive toward each other. If you have fish that ACT aggressive, then they are not being taken good care of, or they are with inconpatible tankmates. (which pretty much amounts to the same thing)
If you want aggressive fish, buy cichlids. The goood thing about them is that you can put a lot of them together, and they are brightly colored. If you take good care of them, though, they will not act aggressive.
Temperament is kind of a strange quality to buy a fish for, unless you are trying to match what you already have. You should buy a fish based on it's level of difficulty to care for.

How about a reed fish?Some people say that they are not aggressive but I had a reed fish and they are not peaceful unless kept with fish with great sizes.Mine had killed 2 eels-1 striped peacock and 1 fire,a small Oscar of size 6'',a parrot child and once I put a goldfish of 5 1/2'' and the next day I found it dead.The reed fish tore its stomach and it had no internal organs visible!!!!Very aggressive....When it swims, it looks way cool.You can't get any cooler than that!!!And you can have 2 of them......

ok, feeder fish = diseased puppy. a good thank you to be certain a gradual loss of life for an Oscar or lionfish is to feed it goldfish. do not do it. There are not any fish like what you're describing that may stay in a tank as small as 32 gal. maximum of your greater aggressive predatory fish desire fifty 5 gal minimum.

I kept red-belly piranhas for a while. Easy to feed, fresh water. Make sure if you get two or more that they are the same size, otherwise they'll start disappearing...
They will, however, eat any other type of fish you put in the tank.
