    We began keeping goldfish as pets more than 1,000 years ago, but their beauty wasn’t the only thing they had going for them. Goldfish had a lot of really weird biological traits that made them incredibly resilient. And in an unfortunate twist, we’re now breeding away the very traits that once made them nearly invincible.

    One thing I've heard is that in China and Japan, they weren't kept in small indoor bowls for long. They'd be out back in the pond, and you would scoop them up for visitors to admire them for a couple hours together while you talked. Then they'd be put back in the pond. European traders who were impressed by the fish didn't understand that the bowls were only temporary, and assumed that was just how they lived. That's probably the root of the current abusive situation for goldfish - colonial misunderstanding.

      Constant chaos, if you live in an area where bass or sunnies are native, they will he!p balance fish populations when reintroduced to native waterways that have been invaded by carp family fish. If you have, as we do, local developments that have 'drainage' ponds with goldfish or carp, then catch some local bluegills or similar and release them into problem areas. It will help.

    It should be noted that folks keep goldfish in tanks WAY too small to fit them properly. Goldfish ideally get anywhere between 8-14 inches long, so a healthy enclosure size for even a single goldfish is *at least* 40 gallons, preferably larger. Do that, and you'll have a very happy, long lived (up to 30 years if kept properly!) and personable Goldfish.

      Yup. I always recommend people get guppies first, far easier to care for, can tolerate high ammonia, can live in fresh salt of brackish water, tolerate low oxygen, produce way less waste so need fewer water changes and imo are much prettier and do fine in a 10 gallon where thats too few for even a single goldie

      @littledreamerrem7021 Před rokem +16

      That's for non-fancies. Those guys honestly fit better in a pond than a tank. For fancy goldfish, the general rule is 20 gallons for a single fish +10 for every additional goldie. Since they're social creatures, you're looking at a bare minimum of 30 gallons, with many keepers defaulting to 40 anyways.
      Even in a properly-sized tank, you have to carefully monitor the water parameters due to how messy goldfish are. The larger the tank, the easier it is to keep the fish from killing themselves with their own waste. I'm personally stuck with a 30 gallon housing two ryukins ATM due to space limitations, so I'm compensating with a heavy duty filter set up. I love my goldies, but I would never call them beginner fish. They're hardy, sure, but they have care requirements outside of many people's expectations.

    Goldfish are also super invasive if released into the wild, and are a huge problem right now where I live... they grow much bigger in a large body of water with unlimited food, and natural selection means that a lot of them revert to their original brown color because it's better camouflage

He died after a storm the filter went dead; the water drained through the air hose. The rest was history. Philip the fish was approx 30 cm head to tail at time of death. When he came to my bedroom he was about 5 cm head to tail. Classic fish shape; grey in colour. Suspect he was more carp than gold. These things are real pets though with personalities.

      Carp induced declines in water quality causes declines of aquatic plants needed by waterfowl and fish

    Grandpa always had two cows. He would get a yearling, and butcher the other one every year for meat.
    He had four goldfish in the old cast-iron bathtub that was the cows water tank. They did a pretty good job of keeping it clean. We would still have to scoop some stuff out of the bottom of every couple of years and clean it out but the fish had plenty of food in there. None of them ever got sucked up and drank by a cow. In the winter we would go break the ice on the surface so the cows could get a drink and the fish are still swimming around under the ice. They lived in that tank for a lot of years.

    I would like to add something to the explanation of allotetraploidy. It is true that being tetraploid means having four sets of chromosomes and thus more copies of a given gene for evolution to work on. However, allotetraploidy means the organism became tetraploid after a hybridization event vs. autopolyploidy, where no hybridization takes place. So, it is not only that the goldfish has the chance to carry more alleles, its genetic makeup was more diverse from the start. Hybrids also tend to be pretty hardy. These kind of processes are very common in plants, less so in animals with fish being one of the exceptions I know of. Always blows my mind, and I will never look at a goldfish the same way again.

    If goldfish are being bred to be less resilient it might be better for the well-being of future generations of pet goldfish. Maybe people might be forced to keep them in halfway decent conditions, keeping a goldfish in a bowl is like keeping a dog in a crate and never letting them out at all. If goldfish didn't survive such abuse, neglect and bad water conditions so easily people might care a little more about improving their pet's living conditions. A heathy goldfish can live up to 20 years and be trained to complete and memorize an underwater maze.

Common and single tailed goldfish are 75 gallons for the first fish. If you can go bigger, always go bigger.

    Goldfish are amazing pets, it's one of the fish that have been domesticated by now and they are amazingly looking.
    However, goldfish are often kept in the wrong conditions for hobby fish keepers due to their popularity and commonly held misbelieves and end up being unintentionally abused.
    They need a much larger indoor fish tank than commonly assumed (bowls are def not ok for them), they need a variable diet of protein and veggies, regular water changes and they need water movements so the oxygen exchange at the water surface can be more efficient.
    Please be more mindful when keeping goldfish (especially for kids).

      @Kecking Rabbit Definitely. I recently moved one of the ryukin, my newest, from the 20 gal hospital tank he was quarantining in into the main tank, and even a 10 gal difference is night and day! He loves the extra space he has to do fishy things. The only reason I don't have a 50+ gal is the space limitations I have in my current abode. As soon as I'm able, these guys are getting a mansion. Maybe even some more friends to goof around with!

    I am keenly aware of the problems associated with invasive species. I keep a few goldfish in my little artificial pond for both their beauty and because they thrive there, and because they consume mosquito larvae. They are also able to withstand winters in Northern Virginia, and are in no way able to be introduced into the already carp family contaminated local waters.

    Can you next talk about the genetic divergence of goldfish? For instance, since they have 4 sets of genes, wouldn't one see greater variation over shorter periods of time? Any geneticists out there who can ixentify specific differences in populations across the world over the past ~150+ years that are significantly different from earlier population traits?

    I lived near a retention pond made of some kind of brick or something like it. There was a Target next to it and the other side of Target was a Petco. There was a Petsmart less than 1/2 mile away as well.
    In the retention pond was a large school of little goldfish. No idea how the goldfishy got there. We assumed people “released” the fish after “saving them” from the pet stores. Drains along many of the streets emptied into the pond as well.
    My son and I had a picnic nearby to watch the geese and their young goslings. I noticed a bird flying around over the pond. It would dive down a few times and fly off, then came back. He mentioned the bird had something orange in its beak. I watched it and yep, it would dive and fly back up with goldfish in its beak. I saw it dive 3 times in one visit and would fly up from its dive with more and more goldfish. Then leave and come back for more.
    A few days later we didn’t see anymore goldfish in the pond. We never did see another goldfish ever again in that pond. Idk what they lived on (goose feces?). Maybe the algae that grower on the bricks (probably).
    It was crazy

    Separate goldfish story: My mom had to perform a one-finger Heimlich maneuver on my goldfish, Domino, at least two times. He liked to suck on the rocks at the bottom of his tank, and sometimes he would find one that was too small and get it lodged in his throat. But he survived being taken out of the water and basically squished repeatedly until he coughed up the rock. After the second time, we got him glass marbles instead. :)

    We had an accidental goldfish pond when we left our above-ground pool uncovered and unused for too long. It got pretty gross, and my parents were worried that it was a breeding ground for mosquitos. They bought a few goldfish to eat the mosquito eggs/larvae, and then we kind of just forgot about it. Much much later, there was one goldfish left; he was probably about 10 inches long and just living his best life. We eventually let him go into a real pond. I like to imagine he still lives in that pond and is a 2-3 foot orange monster now.

    You showed two different kinds of goldfish with bulging eyes. One has side facing eyes, one has too facing eyes. Especially the latter cannot use their eyes properly and always faces the light, and it's basically animal abuse. The other type, I think is animal abuse as well but it's less clear cut since they might be fine with those eyes. They can still easily pop their eye if they bump into something and that makes that eye blind.

  • @Biohazbird

    It goes without saying that just because a goldfish can SURVIVE in harsh conditions, doesn't mean they're not suffering. They can only live with almost no oxygen when the temperature is low, and it's easier for them to become obstipated and develop swim bladder problems because their metabolism has slowed so much in these conditions. Goldfish can withstand a range of temperatures, but a RAPID temperature change can kill them. Goldfish are also more sensitive to rapid ammonia spikes, especially because they produce a high amount of waste ammonia themselves. I once forgot to establish a nitrogen cycle before moving my little sister's common goldfish to a bigger tank, and in 48 hours his scales had gone completely dull and he started developing minor ammonia burns. (The poor little guy survived because I freaked out and got someone to cover my workshift so I could get some emergency supplies from Petco, but he died a few days after Christmas 2022 from a combination of a persistent flavobacterium infection and a pressure sore he got from swim bladder disease. Turns out goldfish need to be fed boiled veggies regularly for GI health)

    Perhaps unintentional but the slander on the betta fish is not based in fact. Female betta fish can lay plenty more than 100 eggs per spawn and spawn every few weeks.
    They actually represent an excellent genetic model. I have bred and raised a black avatar male with a blue avatar female and have finally created the purple avatar betta!! Their genes and ability to breathe air through the use of their labyrinth organ. Betta fish are certainly comparable in producing a far greater spawn than current genetic fish models in academia such as zebra fish or cavefish.

    Years ago I adopted a single goldfish that a family was rehoming (for free). It came with a bowl so the first thing I promised it was to get it an aquarium. Pretty soon I found a 60L aquarium on one of the free stuff Facebook groups I was in. It had been used as a planter box so it needed some cleaning but I had help setting it up with some special soil and aquarium gravel and of course plants. The goldfish was so happy it swam up and down and from left to right. Unfortunately a few weeks after it was floating at the top of the tank sideways struggling to propel itself. A problem with the swim bladder I suppose. It died not long after 😓

    Goldfish are resilient in someways, and arguably the worst fish for a beginner in most ways. Goldfish use up a lot of oxygen, produce a lot of waste, and need good quality food ( not flakes). Goldfish are quite difficult to keep alive in a tank for how long theyre meant to live (15 years) and naturally get quite big, but are usually stunted from small tank and no food.
    Goldfish, flowerhorns, betas are by far the most abused animals on the planet, literally magnitudes above other animals. We see them as being emotionless, unable to feel pain etc so we deform their bodies heavily for nothing but our own enioyment. Imagine a dog breed thats eyes dangled out of its skull, or had organs crushed together so they constantly die of organ failure. Or have a lump growing out of their head thats close in size to their entire body. Or maybe theyre literally missing body parts like legs, or are selected to grow tumours.
    This is stuff that is common in goldfish and flowerhorns especially. Goldfish dont have to just go through being the animal humans decided would be hilarious to deform and make their existence literal torture, but also decided to breed them to be fed to other animals alive. Its known that goldfish can literally develop depression if theyre not stimulated enough, so swap things around in their tank and give them plenty of space. The amount of suffering goldfish experience is literally unparalleled and is almost like a sick joke resembling something like “I have no mouth and I must scream”.
    Also dont buy fancy goldfish, like ever. As someone who has had years of experience with goldfish, eventually i decided that the ethics behind them means that i will never buy them again. They wont live long, are susceptible to disease, dont swim strong and arnt active, a lot are blind, unable to swim, usually die from completely preventable things, and are even harder to keep alive than regular goldfish.
    If you want something healthy but beautiful, look for a “Shubunkin” goldfish. They are colourful and incredibly graceful, almost like small koi. They live long, grow to the regular size, no health issues that i know of etc. just make sure you buy them from somewhere reputable (not pets at home, or whatever).

It's not so much breeders who have misshapen the gold fish, it's the owners who refuse to give the fish a big enough container to live in to allow it to grow to it's full size. Gold fish will only grow to fit the container in which they live. Put one in a small bowl and they will stay small and bulgy but throw them in a pond and they will grow as big or bigger than the largest of their carp relatives. No joke, I've seen massive gold fish nearly 3 feet long in ponds before.

    I had a goldfish at my parents house that managed to last from 2004 to 2022 or 18 years. Unfortunately, last year, the fish was sick and almost dead, so my dad had to put the fish out of its misery by sticking a spike through the fish's head and buried it, which is apparently the humane method for killing fish.
