THE most aggresive fish

[Gumby131]

hey,
i am getting a new tank stup for my b'day and want to put something REALLY mean in there.
i am currently looking at an elongated piranah but it says there are meaner ones out there.
can anyone help me out?

[Walker_]

Alligator? Or is it Crocodile… whatever the freshwater one is…
I have heard there are some NASTY eals out there…. But really, fish tanks are for calm ,,, imho :D just use neons..

[Onikun]

Red tailed catfish will eat anything that fits in its mouth. It grows to over 3feet long though so good luck.

[Gumby131]

but this piranah is meant to try and attack your finger through the glass, aswell as eating mice and rats that you put in the tank.

[gagaliya]

exodons

[reiverix]

What size tank will it be going in?

[echoofformless]

Cory cats are the most vicious creatures ever to scourge the planet.

You could also try otos. They get really mean and nasty, especially when there's lots of algae.

Mollies and platys are practically the devil incarnate.

Okay okay...all kidding aside. How about a D. Cheneyensis? Tell me this is not the face of pure unadulterated evil:

[BrineShrimp]

Red Devils.

'Nuff said.

[cindy2715]

A snakehead is the meanest fish. I used to own one many years ago. They will eat anything you put in their tank and try to bite anyone who walks past. Mine used to hit his face on the glass so hard trying to bite someone that he would bleed. They are now illegal though and you probably wouldn't be able to get one.

[tai95]

How big of a tank are you getting? Most of the "mean" fish need a large tank. If you plan on feeding them live food mice and rats be prepared to do a lot of water changes.

[led_zeppelin]

id get either one of these

http://www.aquascapeonline.com/store/scripts/prodList.asp?idCategory=237

or a few of these

http://www.aquascapeonline.com/store/scripts/prodList.asp?idCategory=221

unless i could find a snake head, might be a good question to ask MFK.

[vaderbanger]

depends what you mean by mean? anyfish will eat smaller fish but that doesnt make it mean. so maybe you mean overly aggressive? if thats the case yeah id go with red devils too, they are pretty relentless in their killings and seem to kill for the fun of it.
exodons are notorious eye eaters if thats your fancy
red tailed catfish arent mean, their actually pretty sweet and well manered, they will eat anything that fits in their mouth but thats just a food source.
flowerhorn cichlids can terrorize its tankmates and may even kill a red devil matched in size...so its a toss up between those 2 cichlids for me.
i have a 4" red tailed shark thats mean...do you want him? lol
hes in with central american cichlids twice his size and he bullies everyone

[Walker_]

A snakehead ..... They are now illegal though and you probably wouldn't be able to get one.

really? the LFS in the mall has two here, would it be worth my while to buy them up and list them on aquabid?

[sumthin fishy]

Red-devils are rather tame IMO. I would root for a convict of equal size in a fight. Great Whites are VERY aggressive. Since you didnt specify a tank size, I would recomend one of those or possibly a tiger shark. If your tank is a bit smaller, I will agree with echo that ottos attack algae with the same ferocity that pirhanas attack mice.

Seriously, you are going to have a hard time finding the MOST aggressive fish. Theres debate and oppinion and difference in individual fishs' personalities to contend with. Im sure a pirhana is agro enough for you, or if theres something else you like, get it and make sure to give it proper care.

They are illegal in the US. I don't think they're illegal in Canada yet.

[pophead]

it's probably too cold for them to go wild up here.
I would say wolf fish or snakehead too.

[StreetCypher]

They are illegal in the US. I don't think they're illegal in Canada yet.
SH are illegal in Ontario, but i believe thats it, any other province/territory they are perfectly legal

My dear God, you can get FROZEN FEEDER RODENTS, DO NOT USE LIVE. Frozen feeder mice are available at PETSMART for 6 for 9.99 USD, they are NOT hard to find.

Or does drowning live animals as intelligent as dogs and smarter than horses as rats are turn you on somehow? Live feeding of rodents to other animals is considered animal cruelty and ILLEGAL in some countries (like the UK and Australia), but sadly not in the US. Of course, the UK has been breeding rats and mice for SHOW for over 100 years.

I have fifteen pet rats and a few are pedigreed show-quality animals. I love them like most people with heart love their dogs -- they're affectionate, learn their names, learn tricks, give kisses, VERY rarely bite, cuddle with you, follow you around the house like a puppy, you name it. I love them like most people with heart love their dogs and cats.

I see a lot of talk about how fish should be considered companion animals and treated humanely on these forums. Why doesn't this extend to companion rodents as well? Those little rats and mice you buy out of those feederbins and toss helplessly into one of the the most terrible deaths possible could make one of the most wonderful pets you've ever had.

The frozen mice and rats sold in many pet stores are HUMANELY EUTHANISED, usually using CO2, before they're frozen and offered as a food item for your other pets. Plus, they're gut-loaded and a healthier alternative for your animal.

USE THEM.

[shaunakadub]

About the snakeheads....

Please don't buy one. If you do, make sure you have the appropriate housing until it dies. The snakeheads are similar to snakes in that, once the owner can no longer take care of this fish, they release it into the wild.

The problem with that: They kill everything they can, they spawn like rabbits, and can live in pretty much any water condition & temp. We are having a huge problem with these up in my area because someone released 5-6 of them into a local waterway, and since then nothing has been the same.

Its perfectly natural for live animals to be eaten by predators. Should we go through frozen euthanized rabbits out in the woods for the mountain lions? I don't know if I could watch it, but I don't think its such a bad thing.

Have you ever been tried to breath where there is no oxygen? Its awful, How can you say that that is humane? I personally wouldn't trust a pet store when they say they are humanely euthanised, and for what reason would a frozen mouse be healthier than a live mouse?

[cherrypie]

Here in Australia, keepers of native fish generally consider the Black Bream (Hephaestus fuliginosus) to be the most agressive, generally any fish that is added to a tank with one gets killed (heard many stories of far larger barramundi, murray cod and sleepy cod being killed by them).


Live feeding of rodents to other animals is considered animal cruelty and ILLEGAL in some countries (like the UK and Australia), but sadly not in the US.

As far as I know it's not illegal in Australia (though commercial breeding of rodents for that purpose may be). I can even drop in a link to a government site with a "how to" guide of breeding rats and mice for live food. Obviously if the fish (or animal) in question will readily take dead food then feeding live food is potentially unethical (depending on the food in question, I wont lose any sleep over mosquito larvae, blood worms and brine shrimp), but sadly that's not always the case.

[sumthin fishy]

thanks joe, I didnt want to start the debate on that, but I will back you up.
I agree that "humain euthanization" involving C02 doesn't sound right.
She did say the mice were gut laoded and that was why they were healthier. I could see doing the same thing with live mice, feeding them a diet that would benifit the preditor who is scheduled to consume them. I do feel it is somewhat natural for a preditor to actually have to catch its prey, and if it is anything like I have seen (I have not kept FISH that ate live mammals), they hardly have the time to drown before they are consumed. FWIW I used to keep/breed red-tailed boas and fed them live mice, then rats, then bunnies or chickens. At the same time, I had pet rats, a hamster and mice, which were strictly pets which a showed the same care for as I did my snakes and fish. Honestly, the live foods have some chance of getting away, but that poor, poor letuce I used as a treat for the rodents has no legs or any other means of escape. :(

Someone needs to go get themselves a copy of the Lion King and watch it a few times.

Now, all that has been said, but I would like to point out that mamallian fats are not water soluable and should not be fed to fish live OR dead. There are much better alternatives in the form of live or dead aquatic organisms to choose from.

Well, this guy--catfish unknown species- could be really fun for you to play with--aggressively HUNGRY,
he obviously will put anything in his mouth. Or, you could just get a fighting pit bull for a playmate!! :D

:OT: I beg to differ (gently) on your statement that rats are more
intelligent than horses. Having been around horses most of my life,
having rehabilitated an abused, high-strung mare into a wonderful
companion, and raised 2 from birth, training and riding both (one is 9, one
is 3), and livng on a horse farm for the past several years, I have found
that most horses are smarter than most humans--and they have alot more
common sense. I'm not talking about show horses, who are a different
kind altogether. Dogs are capable of learning human vocabulary to over
300 words; horses are a bit over 200. Their range and depth of emotions
is staggering, and they often outsmart humans. No, they aren't cuddly,
but they give kisses too, and follow you around full of curiousity.

I concur that rats can attain a level of intelligence--my sister had one for
several years, but I really argue their superiority over horses. Just my
two lira worth. :)

[cindy2715]

These fish are MEAN. I had to keep bricks on top of his tank just to keep him in there! He finally died. Parasites I think. I just could not get him better. He was 18 inches long and ate about 40 feeder goldfish everyday. Very cool fish. Once went fishing. Caught two Bass, both were 6-8 inches long. He ate them both, one right after the other. These fish can wipe out an entire lake. That is why they are illegal.

[awesum]

Snakeheads are more aggressive than pirhana's. well from my experience.

There are a lot of pirhana species out there. I wouldn't get red belly's that's for sure. my friends red devil killed a red belly P before and the P was just as big as the red devil. Red belly's are weak. They are like pacus with bigger teeth. You also need a school of P's to make it interesting.

With a Snakehead all you need is one of those and you'd be impress. I've seen a 12" snakehead bite a 12" catfish in half off of one bite.

A lot of fish will eat mice, snakeheads, arowanas, gars, etc.

[rosita]

Going out on a limb, here, but I don't think that Gumby131 needs to have
ANY of the type of fish we've discussed. Just a feeling. . . . . .

murray cod eh? jesus they must be bad asses if they can bring down a one of thoise

[reiverix]

He was 18 inches long and ate about 40 feeder goldfish everyday.Most likely the reason for its demise. My arrowhead puffer gets two (thawed from frozen) fish per week, or the equivalent in mussels or shrimp. It is very aggressive but not mean. It knows who feeds it and is quite fascinated by me. Intelligent in fish terms anyway.

[hmt321]

green sunfish are hands down the most aggressive fish i have run across

it was so mean that it attacked the python vac when i would clean the tank out. I would say that it bit my hand 85%-90% i put it in the tank.

the best part is that if you live in the US you can probably go catch one for free.

my 2 cents

[mandimoron]

My betta is pretty mean, he's bitten me on several occasions. >_>

[graphicdesign_r]

I have a mean white cloud that attacks my arm viciously when I put it in the tank. If he was a few feet bigger I would be terrified to approach him. :laugh:

THE MOST AGGRESSIVE CICHLID

Umbee
Dovii,

both get to be like 2ft at least and will eat ur hand, and probably kill any of those other fish any1 has talked about, except for maybe the red-tailed catfish.

www.aquamojo.com and click fish links and see his dovii and umbee and red-tailed catfish.

<GASP> Don't suggest that fish! They're killers! :laugh:

[Genral72]

Really it depends from individual fish to individual fish. For example I have heard that pirahnas can be boring. Or people will have an extrodinarily mean gourami(like me).

[cichlidbryce]

i would say try to find a fish that people say is mean, like the jaguar cichlid is mean when it is captive bred, but tends to be more aggressive when they are wild caught

[cam191919]

this thread is three years old...

[platytetrafan]

Well about a week ago I was watching animal planet and saw what a pirahna can really do to another tropical fish I'd say they are pretty mean not sure what other fish could top one.

[bingala]

try to get a red terror...there pretty mean!

[Blue_Ram]

Arowana might be a good choice! But you should consider how large your tank is going to be. An arowana needs a very large tank. Same with most mean fish though. Good Luck!

[planted29]

Its perfectly natural for live animals to be eaten by predators. Should we go through frozen euthanized rabbits out in the woods for the mountain lions? I don't know if I could watch it, but I don't think its such a bad thing.

in the wild the animals have a chance at escape. any mouse dumb enough to walk into piranha infested waters in the wild and not turn around and climb back out is just helping evolution. but when you take one and throw it in a tank to swim around the top it has no chance of escape. and if i were a mouse i would definitely take a co2 gassing over having my legs and tail bit off and my stomach ripped up. that argument is very illegitimate.

I agree with the cat!! they are so vicious with their prey!

[SilverDollarMan]

with out a dought get a snakehead

i usto have a snakehead in my old 95g, but then they became illegal in my state so i had to get rid of him :(

so if he is not illegal in your state then a snakehead is your best option and will eat 'anything' that you drop in the tank

[mel_20_20]

I'm a human.... The word humane comes from that word. Look up the meaning of that, if you don't know it?

Because the natural inclination of the majority of humankind is to treat others, sentient or not, with compassion and mercy, and to abhor the unnecessary inflicting of pain and suffering on another living creature.

I think that saying "this is how it is in nature" is a rationalization to justify a sadistict thirst for blood and suffering.

Our fish in our tanks "'aint nature" friends They live in a glass box, in an environment that is artificial. Their lives aren't natural. Their water is treated and filtered, and their tanks are decorated... or not.


If they enjoy frozen mice, and get as much nutrition in frozen mice, as they do in a pitiful, terrified, creature that has to endure an agonizing death, then why not give them a frozen thawed mouse.

I think it is very sad that there are people that can enjoy watching a terrified creature, swim for its life, wildly desperate as it tries to escape, and then have its belly ripped open and entrails pulled out; suffering searing pain.

Go rent a Quinten Tarentino movie. Sad to say, that's not enough. People want reality. Does the mouse scream or does the water entering it's throat muffle the sound?

Too bad. I'm sure the screams would be much more gratifying.

[SilverDollarMan]

to calm your nerves, i never fed my snakehead live food, always frozen food food or meat from the butchers (had him for 4 years)

Thanks Silver, you are good as gold in my book.:)

How did you get rid of your snakehead? They are devastating to the environment. I hate to say it, but I hope you killed him.

Haha, I recognize your name. You'll see for yourself soon enough amigo. ;)

They're extremely aggressive. I can't imagine what they'll be like as adults.

They don't devastate the environment when the stay in the aquarium - it should be illegal to release a snake head not own one. IMHO

If you are for regulation have owners register and report if they get rid of the fish or the fish dies - the state conservation department could pick up the dead to verify that they were no released and do yearly checks to verify possession.

Volcano's devastate the environment - we should outlaw those too (I know this is not a valid argument but I thought it sounded funny

Mine used to hit his face on the glass so hard trying to bite someone that he would bleed. They are now illegal though and you probably wouldn't be able to get one.

I agree.

I was picking one up that jumped out of my tank and it bit my hand drawing blood. Another time cleaning the tank it got me on my bicep again drawing blood. The fish was only 4" long! It could eat 12 goldfish in less than 45 seconds and it never missed a fish it went for! They are quick and deliberate not spastic like a Piranha or clumsy like an Oscar.

[SilverDollarMan]

How did you get rid of your snakehead? They are devastating to the environment. I hate to say it, but I hope you killed him.

some marine biologists came and picked him up, i couldnt euthanize him myself, I had him for 4 years and I couldnt bare to do it.

That Sucks! Sorry to hear it. I have a good feeling that it was in good hands and that you are not the type of person to release it into the wild.

Question: Would you have agreed to registering the fish and yearly inspections to assure that it was still in your possession? Just curious...

[johnlarson66]

Any one know what kind of fish the OP ended up with?

[IceH2O]

bump,

Its a sad story really.

He ended up with a 225 gallon tank and found out that 1 piranha can't do nearly the damage as a shoal of 6.

He had them about 6 months then one day while doing a water change the stool slipped and he fell in head first.

Don't worry he didn't die. But you'd never recognize him now.

[RisiganL.]

Umbee or Dovii are the most aggressive IMO.
