Fairly self explanitory, post what you think the hardiest fish you can buy for aquaria and say why its unkillable. And also feel free to damn anyone elses ideas, this is a quest to find the hardiest fish around.

Id say the winner was the climbing perch, Anabas testudineus. Having the labyrinth organ, it can breath atmospheric air when O2 levels in the water become too low for it. It can live happily in a huge range of temperatures, pHs and hardnesses. It is covered in tough scales and can take unwanted attiention from other fish. It can happily take a day or two from a powercut in its stride. Climbing perch are truly remarkable fish.



Oh yeh, and if they need to, they can walk along land over several hundred meters to find new water.
 
I say common goldfish. Because of all they've been through, they deserve to be hardy :p.
 
clown loach. i once clean the ornament and left it in a bucket of boiling water for a while with out realising the poor thing was in one of the cavity :shout: . when i lift it up, i can head this clicking noise and found it in there i quickly put it back in to the tank, thinking it will die soon. :rip: but no it acted as nothing has happened and goofed around with the others. :stupid:

ok. spoken too soon. my loaches are having a bad dose of ick. two have died :sad: :-(
 
Well my brother's fish tanks seem to always be forgotten and very neglected, and he seems to end up with one large pleco in brown stinky, cant hardly see thru it water. So I would say The commom Pleco.
 
Goold fish by far. They have been known to live in nitrate levels of almost 800 ppms.

Your statement

"Id say the winner was the climbing perch, Anabas testudineus. Having the labyrinth organ, it can breath atmospheric air when O2 levels in the water become too low for it"

I disagree with this, I have multiple spotted leapord gouramis, a type of climbing perch from africa. They are highly agressive towards each other and while hardy, they sometimes kill each other and will kill themselves by attacking images in aqaurium glass.

There is absolutely no fish that is impossible to kill in my opinion. But some of the hardiest IMO are:

1. Goldfish (but can easily carry disease and kill other fishes. With hemmoraghic septicima and other deadly diseases, they should be kept in a coldwater aquarium by themselves.
2. Plecostomus (They are hardy, often get big, and are skiddish, but they do a good job and live for a while.
3. Angel Fish (Many say they are weak and die easily. I definately ddisagree, once they settle into a tank, nothing short of a rapid ph change will kill them.
4. Large Tetras (the larger tetras can be extremely hardy and beautiful additions to a tank
5. Rainbow fish (Beautiful tough scaled fish from Australia)

Weaker fish to avoid if longevity is what your looking for!
1. Scaleless fish, such as Clown Loaches and Knife fish. They develop columnaris and ich very easily and are difficult to treat as they can even be killed by some of the meticines that treat that disaease.
2. Livebearers, Quick to breed, quick to get sick, quick to die, as simple as that.
3. Gouramis (Many will grow large and live long, but just as many that live, will die very quickly from disease and stress. They do have labrynth organs that allow minimal amounts of oxygen to be breathed from the air, but the things that cause oxygen levels to drastically fall in fish tanks, will still quickly weaken their immune system, and they will die of a bacterial disease, rather than from sufficating.
 
Piranhas by far are the hardiest fish there are.

I've seen some with their innards literally hanging out and half their body gone but fully recover in 3 or 4 weeks.

I've seen another that had his stomach opened up from a bite from another piranha and whenever he ate, most of the food would pass back out of his body from his open stomach and into the water.

Both of these piranhas healed up and lived many many many years after that.

There are many other stories of the healing properties of piranhas and how they endure pain and suffering to heal and live. No other fish has the healing properties of piranhas. Not even close.
 
I beg to differ about the danios! I manage to kill 5 in one night! :crazy: Seriously that was a fluke.

I have a Mickey Mouse platy that has survived everything!
 
Desert Goby, Chlamydogobius eremius

Desert gobies can tolerate temperatures ranging from 41 to 104 degrees Farenheit, they can live in pure freshwater up to a salinity as high as 60 ppt thats TWICE marine salinity. They have been found in oxygen concentrations as low as 0.8 mg/l. Also can tolerate a PH between 6 and 9!

surley no other fish can boast things like these!

I would say common and sailfin plecos, comet goldfish, WCMM's (white cloud mountain minnows) and certain varieties of danios are all very tough fish. The problem with goldfish and plecos though is that they need very large tanks to be kept in, so although they are cheap to buy and feed, they can also be very expensive to accomodate.
 
although not an aquarium fish, i would say the dogfish

I caught a 10 pound dog fish in a lake once
we got him in the boat and killed it (or so we thought)

about an hour later, we started to filet him and half the body was filetted and the fish started flipping around, fighting. so i would say the dogfish
