What's the meanest fish? Most aggressive? Heck, I don't know, but let's make this the place to confine that talk.

Here are the "most aggressive" links I've scrounged up. Continue the discussion here, let's try to keep it civil and intelligent.

And there's plenty that I decided to not include. Kind of a common question, eh?

I vote for the redline snake head for sure. It's the meanest fish I have ever owned by far, thats counting Oscars, Pacus, Pirahnas, and so on and so on. I had a few of them over the years and they are the only fish I was really scared to put my hand in the tank with those bad boys.

As far as fear of putting a hand in a tank it seems like "rhoms" are rather frightening. This includes the risk of severe damage from dental gear!

I'd have to say a mature Jardini Arowana could put quite a few fish to shame. Cichlids are mostly agressive for territorial reasons, Jars are just nasty period. Mine at 17" must be kept by himself and has killed and/or nearly killed his fair share of the "most aggressive" Cichlids out there including Timaculatus and Citrinellums. His name isn't Satan for nothing!

My vote has to go for red snake heads I've kept a little (and sometimes alot) of almost everything and I have never seen anything to match a full grown red

p.s. you probably dont want the list of fish I fed it

hoplias malabaricus - 2
channa micropeltes - 0

to be fair though, I have read plenty of anecdotes of these situations going vice-versa, but the tellers of these anecdotes left no impressive pics by which to remember them.

In the first pic, both specimens WERE about 15" - I'm sure the wolf has grown alot since then, and the snakehead, well...:laugh:

In the 2nd pic, both specimens were about 3-4"

Micropeltes are not "aggressive". Actually none of my snakeheads were aggresive. If they cant fit it in its mouth then they ignore it. Usually they will try for shits and giggles though. Any of the hoplias are much more aggresive. This aggresive thing is kinda juvie.

Leave it to Filo to mess threads up... :)


I too have heard on numberous occasions that Hemibagrus wyckioides (Asian Redtail Catfish) is one of the, if not the the most ill-tempered fish known - Hemibagrus wyckii (Crystal Eyed catfish) too has a pretty bad rep.



But imo. the first issue in this thread should be: how to define fish agression? You can't compare territorial agression to pure intolerance towards other animals, or feeding-related agression: it's comparing apples and oranges...

So, instead of a thread about "the most agressive fish", the question should be broken down in segments: What is the definition of agression? What types of agression do we know? What would be the most rotten examples for each type of agression?

Let's define aggression, agreed! Feeding doesn't count, already eliminating Filo's choice. It seems that it could be simplified into intentional injury inflicted because of any reason other than food (for our purposes...).

like inflicting injury cause of territory or breeding (guarding eggs), theyd strike

more outta defence rather then just being dirt bags i guess right?

Nah, they can be dirt bags too, just not dirt bags looking for a meal!

Jagaur Cichlids...when breeding, putting a hand in the tank means loosing that hand...or any of the Doviis. Alligator gars are pretty mean, but very few keep them in home aquaria.
