Good question....lots of contenders, most aggressive i have had experience with has to be 2.5ft Mystus wyckii, asian catfish reputited to be "the most aggressive freshwater fish" there is!!!! Ours grabbed a heater and pulled it out of the socket!!! They will attack anything that is put in with them, if they cant eat it outright they will dismember it..nice fish

well the most aggressive fish iv kept would have to be a 5.5" Chinese algae eater. My Jewels, Green Terror and firemouths are little angels compared to him. The CAE went after my Senegalus the most. They look so harmless in the LFS.

i only had one for a few weeks, but i'd also go with mystus wycki as the boss. these fish are aggressive with everything, including yourself.
also some other categories worth a mention are (males in particular for cichlids)
general cichlids, butifekeri
tangs, tretocephalus or petrochromis.
malawis, fueliborni or petrotilapia.
and finally and unusually for small corydoras type armoured catfish.
corydoras (or whatever the current genus is) barbatus males when kept together.

Schleropages Jardini or Australian arowana, Flowerhorn - both best kept solo in a tank.

Anything this small that takes on anything this big gets my vote!

the most aggressive fish i've ever had was without doubt a red line snakehead (chana micropeltes)
a very interesting fish to keep, but an absolute lunatic
he ate numerous amounts of fish on me

i was only keeping fish for a short time at this stage and had a rekord 120, hugely overstocked with tetra's of one sort or another, i had a bit of a fascination with them at the time
the snakehead was about 2", it was a decision between him or a kuhli loach if i remember correctly
he was a little more expensive but a lot cooler looking
so i bought him completely oblivious to the species, temperament, potential size, growth rate, etc. etc.

so to cut a long story short, about a week later, half the tetra had been eaten
i had to choose between the remaining tetra or the snakehead, as cold as might sound, i have to admit that i chose the latter
he was about 16" when i moved him on, he broke heaters, thermometers, ornaments and he almost smashed his way through the tank a few times
i've had loads of different snakeheads since, currently have 4 (in much bigger tanks)but none have come close to him
a great charactor, a great learning experience but not very feasible to keep

i have or have had a nice few predators over the years, an african tiger fish, 2 arowana's, a wolfe fish, gars,
needle fish, bichirs, a monster fish, perch, a stonefish, arrowhead crabs (marine), marbled gobies, big catfish, big cichlids, big knife fish but again nothing has come close to the micropeltes

i used to have an arrowhead puffer, his tank sprung a leak one day and i had to move him into the community tank, nothing in it small enough to fit in his mouth so i thought it would be alright. the next morning he had the stomachs bitten off 2 tiger barbs and 2 big moonlight gouramis. The little bugger was only 2 inch long at that time:laugh: .

a green teror he was a right messer always attackin the other fish....

my channa marulius

I remember working in Fish Antics about 10 years ago,we had a jaguar cichlid close to 18" and my first assignement was to clean the tank of it's algae...
That thing wouldn't tolerate the sponge OR my hand in the tank!!!
A 4foot tank:took me a while to get that done:laugh:
also I have to agree with Des,those Channa are some character alright,eat anything,even too big to swallow...
But when you look at the little shell dwellers like Neolamprologus brevis I think they're pretty aggressive little things
they're little Mike Tyson in a tank:laugh:

The most aggresive fish Ive kept was a male Green Terror. An absolute lunatic of a fish but an awesome specimen. He would attack fish twice his size and generally win too. I eventually had to move him on because the two Oscars in with him eventually turned on him and would have killed him. I gave him to a mate and the little git killed one of his Oscars a few days later. I believe he has been rehoused again .

I agree on the chinese algae eater i have one which is about 6" and has killed a few of my fish. He is a head banger of a fish, ive seen him ram fish even did it to a reflection of himself. He has been removed and is in his own tank.

tiger shovel nose cat fish not really agressive during the day but after lights out total anti christ

we had a tilapia butokofrei that came from the bray aquarium. the maddest fish I've ever kept. Just went mental everytime you even walked by the tank. I've seen smaller ones take on fish 5 times their own size and come out teh better.I guess if we are talking about the most aggressive it would be hard to say..I mean there are predatory fish that just cant be measured as aggressive as they are doing what comes natural (eating fish) but if it's outside their normal feeding times or they are full or if the other fish are the wrong kind of prey then they aren't aggressive??? so I guess I wouldn't call them such. Stuff like larger cichlids seem to be the real winner here to me anyways. males and females in breeding condition take the biscuit, all you have to do is look at a pair of little covicts bashing everything into one corner..they will take all commers. Tricky one to answer I guess.

If the question is any aggressive fish towards humans except piranhas it would be arowanas esp when hungry. One time my silver took a bite of my thumb and it's teeth scratched deep into my fingernails
