What Is The Most Agressive Fish?

If it was just aggressive 'things in a fish tank' I would say my Long-armed shrimp, easily.

Fish... I agree with Chishnfips, a friend of mine had a Fahaka Puffer that went off its food so he fed it live food to get it back on track, from that day on it was an absolute Psycho.

Who do you recon would win dominant species in a tank half and half, Tiger Barbs and Convicts? (Not that I'm considering it... but theoretically)
 
Holy crap! Look at that Snakehead! Hell, he looks incredibly deadly!


As a Guy who doesn't like snakes(only the poisonous ones)are snakeheads like snakes? And are they poisonous?
 
Fahaka puffers are described as exceptionally aggressive. Mine isn't too bad, but last night he did try and eat the back of my head during my dinner.


What exactly were you doing to let it eat the back of your head. lol???? :blink: :p

The dinner table is infront of the tank. i wasn't antagonising him or anything of that nature. I was sat with my back to the tank and he was trying to attack it through the glass.
 
Years ago a friend of mine kept a large snakehead he eventually had to give it to a lfs when it outgrew his tank. It was a very interesting fish with tons of personality. Those eyes had an kinda spooky quality about them, like it was figuring out if it could eat you or not. It was a killing machine!

The absolute most aggressive freshwater fish in the world is the Asian Redtailed Catfish Hemibagrus wyckioids http://www.planetcatfish.com/catelog/speci...p?species_id=19 At an adult size of over 3 feet they are the top predator in their range and anything that they see is food, if its too big it will just be dismantled bite by bite and if theyre not hungry they seemingly kill just for fun.

Red snakeheads come a close second but are only really really aggressive when they have fry to protect, during which time they have been known to attack and kill people by catching them in the neck with their teeth when leaping from the water.
 
I would have to agree with CFC on Hemibagrus wyckioids as the most aggressive FW fish. The most aggressive fish that I have ever owned is my Black Mask Elong Piranha (Serraslamus Elongatus). This fish is a finger chaser (it literally chases people when they walk by the tank) and it's the only piranha tank (and I have plenty of piranha tanks) that I own and I worry about putting my hands in. One time I had a cube of frozen food in my hand and when I went to drop it into the tank the piranha shot out like a torpedo and landed on my chest. Almost sh*t myself when that happened.

LOL, I had to ask , I had images of your head in the tank with a snorkel on. ha ha ha
 
I've seen a Midas cichlid, full grown just about, lunge at the glass when someone put their hand near it. Pretty crazy.

Posts like these make me so proud of my little guy :wub:

Some of the users here may know that I once had a 12'' Hemibagrus wyckioids. He was too big for the tank so I sold him for $150 to a guy with an indoor pond. Now I think I could have gotten more for him... :blink: but then I remember that he is probably ecstatic to get a pond to himself.

In the tank with him, I also had a pair of 9'' Oscars that regularly spawned. Unfortunately, whenever they spawned, the catfish would viciously attack the Oscars, tearing scales, ripping fins, and eventually breaking the jaw of the male. He would then consume the eggs. The Oscars were good parents, and they would occasionally threaten the catfish, only to have him seemingly "growl" at the Oscars, sending them into a frenzied dash to the nearest corner.

I eventually resorted to leaving the light on all night long so the catfish wouldn't prowl. If the light got shut off for some reason, I would end up turning it on and seeing petrified, beaten Oscars and a torn-up Plec and Tinfoil Barb. :crazy:

I will get another one someday. They are incredible cool :wub: I also love snakeheads, but they seem really "jittery" and buying a "jittery" fish makes me nervous...
