Whats the ULTIMATE freshwater monster.

[Chicxulub]

Yup you got it right! You can't have both ways. If you are going throw the bull sharks and other anadromous species then you needs to throw out the freshwater fishes that visited the saltwater environment as well. Seems fair to ya?

GOOD NIGHT! Do you really not understand the difference between a freshwater species and a saltwater species? Just because a specimen of a species might be found occasionally in a habitat that isn't typical for it doesn't make it a denizen of said unusual habitat. Bull sharks are a marine species. ATF, gator gar and most big cats are freshwater. If you don't understand that concept I don't know what I can do to help you.

Who said it's already established a goliath tiger fish is top?

About 98% of voters...

And the debate is not even over!

No good debate ever is!

However, one must embrace logic to participate meaningfully. If you wish to labor under the auspices of including anadromous species, then specify that. Trying to include anadromous species as pure freshwater species is to be intellectually dishonest.

I still say it is krish taking a bath. That would pollute the water enough that would make the eel die of skin infections.

Sounds legit.

If Black Rhom and Goliath tiger fish are at same size, it would be a happy fat piranha and a half eaten tiger fish that still grasping and bleeding out.

Where in the world would you find a hundred pound black Rhom that could do this?

I would imagine you mean caiman, but the thing is caimans arent streamlined lightning fast preds like gatf or aimara. They lurk around, and i dont think they could ambush any of the fish listed on this thread. Including e. Eels, watching a crocodillian going after i live fish, they generally tend to ambush not really give too much chase. So the e. Eel would totally be able to sense one.

There are crocodiles in South America actually. Just like there's crocs in Florida. They are, however, much less common than the alligatoridae crocodylians are in the Americas.

I agree that the animal that got shocked in the video was a caiman.

Okay I don't know if I can clear up this whole bull shark thing but here is my try.

Bull sharks are a SALTWATER species that has evolved over time to adapt to freshwater to insure the survival of their young. Bull sharks are able to live in freshwater because they can adjust their kidney's to help with osmoregulation. If you were to take a bull shark straight from the ocean and put it in a freshwater environment it would die from dehydration. They need time to regulate their salt intake/outtake and it can't happen in seconds it takes time.

For anyone interested I am a marine bio major studying sharks. And I am thinking of doing a study on bull sharks as part of my PhD thesis once I finish my masters.

That would be an interesting thesis. I look forward to seeing it published!

Also this thread is so devoid of giant predatory cats! I really think they are a good candidate for 2nd place or 3rd. Or both. They display indeterminate growth, which means theoretically it can get big enough to eat any of the other fish we've listed under proper conditions. Examples are the wels of river Ebro (sp? Don't know how to spell that) in Spain (yes I know another river monsters reference). Reaching way larger sizes then most of the others found in there native range. Say the same thing were to happen to the goonch or paraiba? Imagine that, goonch twice the size of the one j wade caught. That is terrifying

Agreed. Most big cats aren't really able to kill other large fish efficiently which is what hurts them in my opinion. Somewhere back in this immense thread I listed a goonch as one of my runners up and piraiba and wels as honorable mentions. Big cats are nothing to shake a stick at!

I totally agree with the electric eel not being able to take down a GATF. They are a charge based species, probably wouldn't even see the GATF coming. I do how ever think no doubt a full sized eel could kill a GATF with one shock though but that would be if it was surprised itself.

Exactly. And a well placed bite from the tiger could remove most of the eel's electric organ before it had a chance to use it. I'm not debating the ability of the eel to kill the tiger, I just don't think the eel would take the logical to a human action of shocking the tiger BEFORE the attack, especially if the eel thinks its hidden.

I do not agree with that since 2/3 eels body contains electric organs, meaning from 8' length, there is almost 6' of organs that produce electricity..and as soon as it would feel bite even it would tear it apart, shock would be released as defence.. Gatf would probably survive but shock would do damage to its senses..

What I mean is that a bite from a GATF onto the long, skinny eel would be rather like a pair of scissors attacking a hot dog. It doesn't have to fit the whole half of the eel into its mouth, it just has to bite down somewhere in the middle to cut it in half.

This thread is still going? Has anyone suggested calling it a tie at this point?

Yeah can't wait I'm still in the air to do bull sharks or tiger sharks (which I seem to be coming across a lot more recently).

Well anyways back topic at hand. Although I don't know much about these monster you all are talking about (except the tiger fish) I suspect maybe the gonuch to be a responsible 2nd in my eyes just from what little I do know about true monster freshwater fish.

Oh yeah Rob, i know crocs are around SA but i just meant in the video. Also isnt it only near the coasts? Their range?

And the whole arguement over bull sharks wasnt going to get anywhere. They evolved in saltwater, and as a man majoring in studying shark biology said, if you cant get one and put it directly into freshwater, then it shouldnt count. And the notion of that not counting means that freshwater fish shouldnt count either is ludicrous.

If the eel was able to zap faster, i think it would belong in the top 3 but it only seems to work w/ concentration and the eel knowing its there for a second. And in that second a lot of things can be done to it by a streamlined fast striking predator. A pred doesnt go for the tail usually, mine always go for the head first so the whole its electric organs still work thing doesnt hold up, because its head would be gone.

Does anyone know how large of a fish a river dolphin could take? I dont know how large the biggest one gets but im about to find out

Ultimate Freshwater Fish will be always a bull shark to me, no matter what others are saying, next to Alligator Gar and Black Rhom.

Well if you have a problem with my opinion then perhaps you shouldn't be a mod at all.....hypocrisy at its finest. Tigerfish will be always your favorite fish but if every fish are same size, a black rhom will easily win against a tigerfish no doubt.

pound for pound comparison changes everything.

But in the end of the day, we all have different opinions. We can't change that.
