Pound for Pound toughest fish?

[rumblesushi]

Great replies, I thought you lot would give serious answers.

And yup it's a good point about the intangible factor of whether the fish is willing to throw down as soon as he comes face to face with the opponent.

Something like a trigger or giant puffer or lungfish may have the tools, bone crunching jaws, but unless they have the natural killer instinct to go at it right away, they're going to lose before they even have a chance.

Also something that does need to be taken into consideration is how good a chin you think the different fish have

Something like a wolf fish looks tough, very tough, I imagine that would have to get chomped quite a bit before it gave up or died. Where as arowanas and most cichlids look to have more fragile bodies and heads.

I like the hypothetical sweet science of fish combat, it's like underwater boxing

green sunfish deserve mentioning, too

I want to see an Aba Aba in action.. Who has Videos.

What does their teeth look like? With their body structure, they could quite possibly be fast and agile. Interested to see what would happen with a Channa and an Aba Aba knife.




Oscars? We are talking pound for pound people.. Oscars are giant teddy-bears. I see small convicts destroy slow-moving Oscars.

yeah well the oscars comment came from the same guy who warned that oscars like hard water and that changing too much water will ruin your tank

Marbled goby! Damm I had a tough mother and he took no crap from any fish.

Mystus Wyckii, Catfish. Not had one but have heard they are extreamly aggresive. No tankmate will be safe or owners hands. they also destroy equipment.

I know it is not a fish but how about a sea wasp box jelly?

Sunfish/bluegill/pumpkin ears
I had a 7" redtailed shark and two 3" pumkin ears took it by the head and tail and ripped it in half. They killed instantly what ever I put in the tank.

Walleye look fierce, I hate taking them off the fishing line.
I think a peacock bass and a walleye would be a good fight...

Any of the psuedochromis/bass/dottybacks for saltwater.
Mean, aggressive, and relentless. For small fish they can brawl.

i once watched a dempsey and a convict take out a snakehead that was twice the size.
