Carbon inserts remove odor and toxins from fish waste and start working in hours, unlike beneficial bacteria colonies which can take time to develop in some situations.
These kinds of filters do not allow you to grow a colony of beneficial bacteria in them unless you outfit them with some kind of a sponge instead. Some report chronic ammonia problems using carbon alone to control the fish waste, but it works well for many others. If using sponge inserts instead, these should be squeezed out in old fish water weekly 5.
The Planted Dirt Method This is another fantastic method for creating a self-sustaining, balanced ecosystem to set up your bowl properly I have used based on the Walstad method and modified for goldfish. The typical goldfish bowl setup a layer of gravel, water and a sculpture DOES become unsuitable due to the lack of filtration. Without a filter or plants, ammonia and nitrite builds up to lethal levels. The oxygen level in the water drops dangerously. Goldfish CAN live in bowls, but the bowl needs to be equipped to deal with the waste byproducts of the fish and allow for sufficient oxygen exchange.
If you set them up right, your fish can live for many years in one happily. If your fish are already larger and matured, those fish will need more room to swim and should not be kept in bowls. If you want your fish to grow large in the future, bowls are only suitable as a temporary setup with lots of large water changes.
However, there are no hard-fast rules it all depends on your water quality and making sure the fish has enough swimming space. The situation can vary drastically depending on how large your fish start out, how much they grow, your water test results and how efficient your setup is. A 2 gallon bowl could house goldfish. A 3 gallon one could house The larger the bowl the better if you want to keep a small group of fish.
Will my fish outgrow a bowl? If you keep changing the water regularly, it is a very probable yes. Will stunting hurt my fish? There is no evidence that I have ever been able to find in all my years of study that points to stunting being harmful to goldfish.
They are also the cheapest, though you will need to clean them up more on that in the quarantine section. Feeder fish have a low success rate due to being housed in such poor conditions and most infested with disease, though some report success with these.
Since we intend to keep the fish small this should not be an issue. Bowls can foul quickly due to the smaller water volume if overfed, so be aware of that risk and remember that it is better to underfeed slightly than feed too much.
The rest of the day they should be allowed to graze on vegetable matter whenever they wish. This method consists of lightly stocking and lightly feeding the fish with a weekly or twice weekly dump-out and gravel wash and no filter, and is perhaps seen as the standard care for goldfish bowls today. But I will caution those who want to use this method that there are risks — and I have heard more negative than positive stories with its use. Why does it work for some and not others?
It may be due to the fact that some goldfish are genetically hardy enough to deal with it. Likely there is too much water changing going on.
If you change the water you remove the growth suppressing hormone goldfish naturally produce. If your system is balanced only water top-offs should be required for maintenance. There are two secret weapons I use for this, the first is floating aerial plants which help block out excess light and are better at absorbing nutrients so algae is starved.
The second is the nerite snail, which is the best algae removing snail I have ever owned. They clean off the glass, leaves and objects in the tank like little janitors. They eat just about every kind of algae as well. These are harmless and help to break down debris, making it more bioavailable to your plants. It is common for some brands of freshly submerged soil to create ammonia and nitrite, monitor this for several weeks and perform water changes if needed.
The plant Hornwort is a good nutrient hog. If all else fails and you are just too overstocked you can always add a small filter in your bowl if desired, though in a balanced system this should not be necessary. Parasites can be suspected if the fish were not from a trusted breeder and you did not quarantine them with proper treatments first.
Lastly, you can add an air stone to the bowl powered by an air pump, which is an instant fix that gives you peace of mind. Be sure you have a backup plan in case of a power outage, such as a battery powered air pump.
A dropping pH can happen if the alkalinity is not constantly replenished either by water changes, lime in shells, or soil. The first suspect is the source of the fish. After that, the next question is how you are taking care of them. Get a test kit and keep the ammonia and nitrite always 0, nitrate under 30, and the pH around 7. Goldfish need some form of filtration be it plants or a filter you buy or water changes to keep their water good as they produce waste that will quickly foul it up if nothing is simultaneously removing it.
Following the instructions on bowl setup will get you a long way ahead. If your plants grow fast enough this is not usually an issue, but if they are mowing down everything it is probably time to pick some tougher plants.
I have never had an issue with Rotala Rotundifolia or Hornwort — though the goldfish do seem to snack some on the more tender plants such as anacharis and pearlweed but it grows very fast. The smaller the goldfish the smaller the chance they will be destructive to the plants. By getting a variety, you can help ensure some plants survive and eventually take over.
Not sure if your small fish are actually healthy? Hornwort is my favorite as it floats and does not need to root. If it dies during treatments no big deal as I already have lots more where that came from. Pet ownership is a learning process for all of us. We make mistakes. We learn new things along the way.

This is a very simple, reliable and safe method, which can be modified to your needs, and is outlined in the book Aquaria, A Treatise on the Food, Breeding, and Care of Fancy Goldfish, Paradise Fish, Etc. The goal?
A self-sustaining bowl that requires very little maintenance. This means a little extra time in setup in exchange for way less work from then on. Add a few shells and pebbles, if desired to the bottom. Therefore, some goldfish may be able to live in a bowl with any pump or oxygen, and others may not be able to sustain such conditions.
I had a goldfish live for eight years in a regular bowl without any air pump and throughout it's life it was active and healthy. After it died, I replaced the water and bought a new goldfish. I kept the new one at the same conditions I kept the old one - it died after a week. You never can predict the lifespan of a goldfish or how to care for it; it's not one size fits all. Don't overthink things: feed it, clean the bowl every few days, keep it in water obviously , and hope for the best.
Even when kept in good conditions, gold fish will only grow to a proportional size of their tank. Unlike other aquarium fish, goldfish excrete hormones such as aminobutyric acid GABA and somatostain, that acts as signal of how many other fish and what sized body of water they are in. They do not die from their spines bending and they do not outgrow their environment - they are not as fragile as some here believe and live quite happily in a well-kept bowl.
Equating their feelings and thoughts to anything remotely human is ridiculous. I had a common gold fish as a kid and it lived for 13 years in a regular fish bowl.
No filter. We cleaned the bowl once a week and fed it once a day. Super easy! This article is full of dangerous misinformation about goldfish. A goldfish can never live in a bowl under any circumstances. First off, goldfish get big. Common goldfish grow to over a foot long as adults. They need a HUGE tank or preferably a pond. Second, fish waste going under the pebbles is not a good thing. It doesn't disappear, it stays there and ruins the water quality over time.
Also, goldfish are prone to swallowing and choking of gravel. Goldfish are best kept in an aquarium with sand. Third, fish flakes are not a quality food for goldfish. The gulping at the surface has been linked to causing swim bladder disorder which is often fatal. Fourth, you can't just let the water sit for 4 hours. For the chloramines in tap water to leave, the water needs to sit for closer to hours before it's safe. Fifth, keeping a goldfish alive for a couple months is not something worth bragging about.
Goldfish live a very long time if actually given semi-decent care. The lifespan of a goldfish averages at around 20 years. The oldest recorded goldfish was 43 at the time of death.
A couple months is like bragging that your kitten lived a year or two. Overall, please do not take anything in this article as good advice in terms of goldfish keeping. A goldfish in a bowl will never live anywhere close to it's full lifespan, and much of that life will be spent suffering. If you can't handle getting a very tank tank or a pond, then you can't handle getting a goldfish. Please settle for a different pet and spare the fish.
I have a goldfish that has lived for seven years only on oxygen weed ,fed every two days and whole tank is fully washed every two weeks.. The tank is 15litres with pebbles and oxygen plants are replaced every 1. Well, after browsing around here I feel like I must add my story Adopted my Mom's Comet fish Nana, when Nana was 3ish. No filter, no air pump, just water changes. Her demise happened 4 days after my girlfriend who rarely preps any food , hammered 4lbs.
The night she was obviously dying and did die, I noticed about days worth of fish food on the bottom never, ever, have seen uneaten flakes like that before. I'm no expert or fish whisperer, but Nana was her active, happy self on Sunday and dead on Friday After what I believe we're 8 active, happy years She maybe grew an inch in the 5 years we had her to about 3ish inches - tip of nose to tip of tail I never did any research on goldfish until now, cause she is gone.
I just did what I thought was right to keep her alive, well and what I believe as happy Coincident with hammering incident, maybe I do believe that played a part in her passing Goldfishes don't belong in bowl? Please, if you cared so much about the fishes, you'd just leave them alone in natural habitats rather than keeping them in a fake tank where they are kept solely for your poor sense of entertainment.
The mindset just astonishes me; 'what I do is okay i. Horrible advice. Goldfish don't belong in bowls. Just wanted to throw Something in here. I won 3 gold fish at the fair for my granddaughter who is 2. I did get then a pump and filter and it had improved the quality of the tank..
If I could post a video I would Rebecca h. It makes me incredibly sad that you're encouraging this and spreading further misconceptions about goldfish. Under the proper conditions, a common goldfish's average life span is 30 years.
Thanks for the advice I just won 2 fishes at a carnival and I'm going to be sure to follow these steps!!!! I'm very sad to see this type of information being encouraged. I hope any readers can give what I have to say a chance - I've had great luck with my fish and have helped many others succeed similarly. First and foremost, I feel it should be established that fish are not disposable.
They are not decoration, they are not senseless little toys. Fish of all kinds feel pain. Goldfish have been used in studies to show that no, they don't have a 3-second memory span, and have been shown to successfully navigate mazes for a bloodworm reward.
I can additionally personally attest to the fact that they recognize distinctions among people who they see frequently I believe there's some recent research done there as well ; they are simply more than what most people know to give them credit for, and I'm not quick to blame them.
There is mostly ignorance on the subject, not ill will, so I hope to disperse that. Are they as smart as your cat or dog? Objectively, no. Regardless of this, they are wonderful little creatures who feel, and fear, and want to thrive instead of simply survive.
I personally feel that we should want to provide the best environment for them, not the one best for us. We force them into our lives, after all. I want to touch on a fact that the writer made sure to mention, their goldfish living for 5 months. I've heard at my workplace of goldfish that live for a year, and the folks are always impressed with themselves.
I am always displeased to say that their fish is simply surviving - it is likely suffering stunting, swimming in stressful levels of ammonia, malnourished, and its clock ticking down. Just because it lives, doesn't mean it's living well. We as people can survive just as well in a closet. Give us food and water and we will live, but we don't prefer that, do we? Is it okay that we allow this suffering on a little life that had no say in the matter?
Let's have a little aquarium lingo lesson, here. There is something highly important in fish keeping called the 'nitrogen cycle'. I'll go ahead and explain it in the most simple of ways, and then turn to how it is important. Fish food, poo, and their act of breathing produces what's called ammonia. Ammonia is highly toxic, and is the 1 fish killer. Bacteria in the water naturally establish, and turn this ammonia into nitrite with an 'i'. I remember it like the roman numeral for one 'I'.
Nitrite is also deadly to fish. Finally, different good bacteria convert this Nitrite into NitrAte, with an A. This last stage is nowhere near as toxic as the previous two. Basically, your deadly stuff in the water gets turned into less harmful stuff as good bacteria set up in your tank.
This means less cleaning, less fish stress, and happier environment. If you have live plants, they eat the stuff up. The overall process from ammonia to nitriate to nitrate is also much more swift, as the good bacteria are ready for action in the tank. Why does this matter? In a bowl, or in too small of a tank that you are too frequently cleaning too much of, there is no room for this cycle to establish. Anything that needs too frequent or too deep of a clean kills your good bacteria and restarts your natural cycle.
Not only inconvenient for you, but stressful on your fish, as they once again have to endure an excess of ammonia and nitrites before getting to the safer nitrates.
The whole process of unsafe to safe can take weeks, or many months. If you're cleaning your whole tank, or taking more water out of the tank than not, or removing filter media before its time is up, you're likely killing your cycle. Stress, dirty water, sadness. So while you could theoretically do your best to keep up with the fish waste by doing very frequent, very large water changes, you would just be siding with a lesser evil.
It is true though that goldfish don't need an air pump. Oxygen entering the water is done by any disturbance at the surface, so a filter will do just fine. And yes, your fish need a filter. And yes, you have to do tank maintenance on top of the filter running. The filter can get out the big chunks of stuff that you can see, but it can't change the makeup of the water it doesn't take out ammonia or nitrites, the deadly ones. As a side note, goldfish who survive for some time in stressful waters are likely only acclimated to the ammonia, which is not necessarily a good thing.
It is still wearing down on their health, and too high of a level of ammonia will absolutely still kill them. Admittedly, I'm not sure what the point of the pebbles hiding the fish waste is. It's not like that would stop the waste from dissolving into ammonia - if anything, I suppose it would just hide it so it 'looked better'.
I don't find that to be an extremely necessary or valid point. While plants do help by taking out some of the bad and replacing with oxygen, they are no substitute for proper filtration and water changes. I'd also like to mention a few things about the variety of goldfish. In the images shown, there are a few types of goldfish that I can spy - there's orandas, a ryukin, and a fantail.
Those are all 'fancy' goldfish, aka, the silly shaped ones. These guys can get 8 - 10 inches in size - that's almost a footlong of fish, if you can believe it. They're enormous, they're bulky, and they're beautiful. It sounds a little ridiculous to put store bought little fish in a 29 gallon tank, but they will fill it before you know it; in the right conditions, some of them can reach their full length within a year. What we see in fish in inadequate space is known as 'stunting', and as it sounds, it is a painful and deadly issue that stunts their growth.
They are restricted in space and do not follow natural growth patterns, and that means they may suffer spinal deformities, organ issues or failure, etc. There is really no need to not allow them the room they need, and more on top of that preferably. Comets and other sleek bodied goldfish koi, shebunkin grow even larger and are even needier. They are really meant to be pond fish.
They enjoy cooler temperatures than fancies, will readily eat algae and plant life, are swift and need lots of room to swim and maneuver, and are just as messy if not moreso than fancies. They're often bought as beginner fish because they're cheap and small due to being sold as feeder fish , but they will quickly grow to be extremely expensive and needy if a pet owner tries to keep them indoors and alive, simultaneously.
All in all, I hope this has not come across as offensive or hurtful toward any goldfish keepers or the author. A bowl is not large enough for a goldfish to grow to its intended adult size of 6 to 8 inches.
Well, that might help for a little while, but as that fish grows older it will produce more and more waste, requiring you to change the water almost daily. This is another misconception, most fish will continue to grow until they outgrow the bowl. The rate at which they grow might slow, but they will continue to grow.
Also, the organs of your goldfish will continue to grow and cause a slow painful death for your goldfish. As I mentioned above Goldfish can get over a foot long so a large tank gallon tank or more with a filter is recommended. The best place to keep a goldfish would be in gallon tank with a filter or two that can process approx.
If your tank is 20 gallons you should have a filter or filters that can clean up to gallons per hour. Seriously goldfish produce A LOT of waste. As I mentioned above goldfish can grow up to 1 foot in length and can live for as long as 20 years. Ford Sports Blitz. Our State, Our Heisman. High School Football. Athlete of the Week.
