You killed it the second you said 10 liters, then every 2 weeks for a water change on such a tiny tank? More like every day!
I'm on my 3rd tank with my Goldfish. I got him at a County Fair about 4 years ago, and when I got home with him, I just threw him in a 3 gallon tank. After he stayed alive for a few months I decided to put him in 10 gallon tank. He lived there for about 3 years and grew and grew. So I knew if I wanted to keep him, that I'd need to put him in a bigger tank, so just recently I got a 39 gallon tank. He is so much happier because he swims so much more and he does things now, that I never saw him do in his 10 gallon tank. The only thing that I added from my 10 gallon tank to my 39 gallon tank was a bigger filter, additional rocks, and an aerator for more oxygen. I'm debating on getting another goldfish but he's been alone his whole life so I don't know if he'll like a lil buddy.
Goldfish are naturally social! I had the same situation, a fair fish who lived alone for the majority of her life. However, last summer we got her a friend- a fancy goldfish. Technically, common and fancy goldfish shouldn't be housed together, since fancies tend to be slower and less competitive, but since my fish, Tweetums, was so shy and skittish from being alone her whole life, Blackmoor was a great buddy for her. While at first, she wouldn't cuddle with him or eat with him, they're now great friends- they sleep together, eat together, forage together, and beg me for food together. If you decide to get a new buddy for your fish, make sure to get one roughly his size (If your fish is a common that's bigger than 6 inches, you should probably get another competitive goldie like a comet or ryukin, just because his size advantage over a little pet store fish is so great).
Zilla Woodward heyy, I'm adopting a goldsifh, but I have limited space so the aquarium can't be bigger than 50L mayyybe 60L, how many goldfish can I get in there (and keep them happy)? they are around 10cm long. thank youu
Sophia Vibbes Goldfish need at least 75 liters to be happy, and they need more room as they grow. I'd suggest getting a different type of fish, honestly! Bettas are good for smaller tanks, they're very pretty and are also solitary, so you don't have to worry about getting any others :0
Zilla Woodward I got an 80L tank!! so all good :)
I have a comet oranda and black moor together and they literally do everything together.
I agree,the guy should mention that a goldfish can grow alot and needs at least 30 litres each!
You only need 90 more liters for that goldfish now ! Way to go.
10 Liters? WTF?
10 litres is just fine people who have problems with small tanks probably just do not do there water changes
Lol no its not
TheGameCommentator I agree this is obviously no were near enough for a gold fish but 10 litres for shrimp is just fine at least it worked for me
That's fine. I was talking about goldfish.
10 litres? have you seen how big goldfish get?
Atleast 10 liters? In here (Finland) it illegal to keep fishes in aquarium under 40 liters. I would not even keep betta fish in 10 liters tank, let alone goldfishes.
Victoria Vigilante a betta could live in a 10 liter. Goldfish aren't beginner fish imo. Things like harlequin rasboras, cory cats, bettas, and dwarf gouramis are good beginner fish
Victoria Vigilante I don't think you know but a betta fish could survive in 3to5 litre aquarium :-)
Yep, they can "survive" but they will not be happy. My betta has a 25l (40cmx25cmx25cm) aquarium and I would never keep him in smaller tanks. He is doing absolutely great, he's active and swims a lot! Please don't keep a fish in a small tank!
I Benji they never said the fish would die but it's just illegal in Finland
We need that law in every country I hope they bring it in to my country
Please dont put goldfish in BiOrbs or small Nano tanks advertised here, fancies can grow to around 6-8 inches and commons over a foot long, you need at least 20 gallons for one fancy and 40 gallons for one comet/common goldfish
Goldfish are honestly not a beginner fish, and you cant just wait a few days then dump a fish in a new tank, please read up about the Nitrogen Cycle first
I keep spare filter media in my tanks so i can start a new tank in a day
thanku nice idea
Kayleigh Browne not true I had an Oranda that lived for 8 years in a ten gallon
A fishes size growth depends on the size of the tank, I know somebody that had a goldfish in a bowl for over ten years and it stayed small.
Kayleigh Browne thats waaaaaay too small what you suggest. those tiny tanks are just torture for those poor creatures.
e have a fish at work we got from an event that was held up here. he's now more than a year and a half old and saw 3 different aquariums, new ornaments and filtration devices and got 2 new friends. those guys are really resiliant.
This is a nice tank but very misinformitive since goldfish need MUCH more living space.
Maybe dwarf gouramis or danios.
Niasr
brian chen you obviously do not know what you are talking about, as it is extremely painful for them as their organs keep growing but not their body’s...
@@etherbirds not really true... Goldfish produce a growth inhibiting hormone that is released into the water. Without by daily water changes, those hormones build up rapidly in small tanks. Although those goldfish lived long, they most likely would've been in severe pain because fun fact, their organs don't stop growing, even if the body does.
@clippersown the bubbles from the pump aren't the reason that the pump adds oxygen to the water, it's the water agitation that does it.
Finally a video of goldfish NOT getting blended or killed!
OMG! i'm a first time fish owner and I kept believe I was doing everything right!! I say that great part of taking care of an aquarium is to use common sense. Great vid!
Sorry Maidenhead, you've really dropped the ball here. Given you're previously excellent videos, I'm hugely disappointing
1# It's huge ignorant to suggest a goldfish is a great introductoary fish. As you know, a golfdish is a member of the Carp family. They can grow to be HUGE! Far beyound even most advanced UK hobbists
2# A week isn't enough to cycle a tank?!?!?! A month at minimum is required
3# 10 to 60L isn't anywhere near a enough to house a goldfish, and a juvenile wont remain so for very long
I'd suggest this video be pulled, and a new, accurate video produced.
well, I have a 10 gal and a 50 gal tank at home, and not only do I keep bottom feeders (snails, plecco's, etc..) in the tank, but I also have a magnetic cleaner and a handheld scrubber for the tank. I only need to use the handheld scrubber about every 3 months, the magnetic one i use about every month and a half, and the bottom feeders do the rest (That's in the 50 gal tank btw). The 10 gal tank is the one that i use the scrubber on every 3 weeks...
if its cold water it doesn't mean its easy to care for. Goldfish are bad beginner fish they grow huge and comments should be in like a 120 gallon
+TheGoldenArowana WTF!!!
yeah maybe poeple should look at the white cloud or the fat heads(also know as tuffies or rosy reds).
you could house 5 goldfish in that size of tank.
CrestFallenMoon just chill it's a damn fish
District 942 please shut up. It’s not ‘just a fish’, it’s a living being.
There is a lot of argument if Nutrafin cycle actually works. In my experience if you are cycling with a fish you dont need it. Its my understanding that all water conditioners work the same. Yes you need to add or your goldfish will get ammonia poisoning plus whatever is in your tap water that is not safe for your fish. Goldfish make a lot of waste and the more waste the more ammonia. So no it will not harm the good bacteria in your tank and you NEED to add it every time you add new water.
hey man nice goldfish tank. im sure all of us in the reef world started off with a gold wish tank. i reamber winning a gold fish at the local fair when i was like 6 and put him in a 50g tank. he got to be about 7 inches long. i love gold fish!!
awesome vid! itsgonna help me sooooo much! ill be geting a few goldfish after Christmas and this will guide me when i buy them!!!
Goldfish need 120 litre PLUS... not 10 litre
Mohammed Syed well yeah maybe they have a huge pond and fancies are 20 a fish and +10 id you add more
Luke Grice YEAH
120 liter!?! I would say 250 at the very least
55 l for one goldfish at least
Are you Dumb 120 litre well it depends if it's one goldfish then 30 or 20Litre (double tayled goldfish) a comment needs like 50L but 120 l for one goldfish are you crazy
1.) Don't use substrate, it chokes / constipates fish.
2.) Don't use wood, it scratches eyes and head, especially of large goldies.
3.) 10 litres is nowhere close to big enough for a goldfish. 80 to 120 litres would be more realistic, they all grow huge and live over 10 years.
Darkkomedy my goldfish are 14 years old when i first had them we thourght we would only have them for a month or two lol
Darkkomedy well, you can use sand and REALLY fine gravel, but anything bigger will constipate the Goldfish since it’ll try and eat it, and not be able to digest it
Yeah I have sand
One goldfish should be in a tank that can hold atleast 100 litres plus otherwise stunting of fish will happen and its a painful death for the goldfish.. Goldfish grow massive and really and truly you should put them in a pond. Not the fancy types though. They havent explained anything about Water cycling on here that is one of the most important things to do before buying fish and the test strips are not very good either bottle tests are much better and accurate.
I totally agree with you
Goldfish originate from the huge ponds and lakes and moving them to little bowls is torture
Also cycling your aquarium is very essential
A good amount of beneficial bacteria will help control nitrates and ammonia better than constant water changes. ( water changes are still essential to export other nutrients and debris
REIF ISEPPIC
I recently had to rehome my goldfish to someone who had a pond..Ill never forget him he was 8years old but I know he will be much happier in a big space and hopefully will enjoy many more years of life.
ii+tasiawful1
and a tank needs to cycle fully... not a few days.. More like a few weeks with adding ammonia
Anotehr tip for an goldfish aquarium is to buy an external filterwith some more capacity then you tank actually needs. Goldfish are indeed quite easy to keep but they are very polluting to your tank. regular cleaning an a good filter makes your hoppy a very pleasurable one.
I own goldfish that is definitely not big enough you need at least a 20 gallon tank for one goldfish. Every time you add one add ten. Ore gallons
Thank you for the effort you put into this video. Very useful. Bravo
Goldfish in a small tank is not a good idea. I had a 55 gallon tank for six goldfishes but I felt sorry for buying six goldfishes as they grew bigger. They grew up to 6-7 inches and I had to do a 50% water change in every week. Not to mention, One after another, I bought three over rated filters for that tank to reduce the amount of water changes. I learned, 55 gallon tank is good for 2 to 3 large/fully grown fancy goldfishes.
Yes, once I met a guy who put 22 common goldfishes in a 20 gallon tank. In 5 years, most of them grew like a big red sword tail. What a happy fish keeper !!! Yes, some of the poor fishes survived upto 5 years.
My point is that my pets are also my kids. Why should not I ensure the best possible living environment for them.
Two fancy goldfish need 30-40 gallons, you can have one in a 20 gallon. If you really like goldfish I suggest saving up for a pond or 50+ gallon tank so you can have many goldfish.
♥♥♥RIP Goldie and Freddie, Goldie lived 7 years, and Freddie died a year later from a broken heart.♥♥♥
You can probably manage two baby goldfish. Once they get about 3 inches long they need something bigger though. Try a 100ltr tank, they look beautiful when they have more room
Kinda, they only breed during a certain season though. You can also identify the gender of your fish during the breeding season (Males will get white spots on their gills, females will fill up with eggs and become rounder).
I you want to breed goldfish, do a quick google search. There are like a thousand websites on what to do.
so true, you can never learn everything no matter how good you are, what tanks do you have? i have a 125 gallon planted, 55 gallon reef and a 1,500 gallon koi pond
wow i love the aquariums on your videos
are test strips better than test tubes? i think it'll be easier and effortless if i get the test strips but then again more than all "easy ways" have a down side like if the test strips are inaccurate. id like to get an opinion before i buy any aquarium testing equipment. please and thank you :)
Can i keep goldfishes in 50 gallons of water???
This is awesome! I got to see my gold fish grow big! Yes!!!!
I've just bought a 12 litre tank, people at the pet shop said I just need to wait 3 days after filling it, with the pump on, and it'll be fine to get fish. Do I not need water conditioner then? Also, is it too small for one goldfish? The glass lid is getting splashed an awful lot from the pump, should that happen?
That tank that was set up would be great for white clouds.
@1:27 I am using same sized gravel, love it that holds nice live plants too like asain fern , anubis etc hard leaf plants also helps me holds lots of bacteria, do not use Tahitian moon sands, moon sand waste of money and time.
People say to give a gold fish ten gallons, because of how piggish they are, also if there not the small algae eaters they will get big and territorial.
my tank is stocked with tiny fish but I'm over the limit a bit but I'm not worried because of how many live plants I have in my tank and my regular up keep.
im getting a 160 ltr fish tank, how long do i have to leave it running befor i got to put fish in it
My friend has a 5 gallon with 3 fancies in it. its been that way for almost 3 years now and they're still doing good.
i have five normal goldfish a black moor goldfish and two algea eaters in a 20 gallon tank, is that o.k. for that many cuz one is really huge and the others are half it's size and im worried the others won't grow to their full potential or they will prevent my big one from growing anymore. if u could help out id appriciate it.
why is he feeding goldfish tropical fish food lol
@casper20096 Weird, your comment shows up in my email but not here... Anyway, 60 litres is not quite enough room for a goldfish, they get too big. You would need at least 76 litres for one, and an additional 38 litres for each additional goldfish. They are very messy too, so you would need heavy filtration as well.
Nice tip about rinsing the filter with the old water instead of tap water. Mental note to self.
Few days I'm sorry my tank was cycling for more then 3 weeks and that included plants
Yes from my own experience, you should upgrade (to something at least 60 gal) as soon as you can. Goldfish produce a lot of waste and need AT LEAST 10 gallons per small goldfish. With the algae eaters, if they're plecos, you have a problem and will need to have an even bigger tank (the common pleco get up to 24" and shouldnt be sold to anyone without a 90+) and may have to separate them due to aggression issues (not fun). With a 20 gal, you'd have to get rid of quite a few fish. Hope this helps
Its no wonder why they water quality would be poor, all these tanks are wicked over stocked xD
A 5 gallon still wouldn't be large enough. Try 10 gallon. They're very cheap and easy to maintain. To clean, use a siphon as seen in this video (long tubey thang) and an algae scrubber. It's easier than you think!! Don't be discouraged! There are also many websites devoted to goldfish with valuable information.
Why are large fish tanks easier to keep? O.o
how many times a day do i hav to feed them? =)
Don't clean your filter and change the water in the same day!!!
Doing Bonsai as a semi-professional, imagine how much i want to put a little tree inside a tank like this...and film the whole thing!
What's the smallest fish tank recommend for just 1 goldfish? I just got a baby goldfish & I live in a college dorm so I don't want anything too big.
Id say a 10 gallon
Do you know why Goldfish need big enclosures? It's not the size of the fish, but rather the amount of waste produced by the fish. Goldfish produce so much waste compared to other fish, so it wouldn't take long for the water in a 10 gallon tank to degrade and build up nitrates. If the water quality is subpar, this stresses the fish, stunts their growth, and eventually deteriorates its health. With that said, it's possible to house a goldfish in a 10 gallon tank if you don't mind doing water changes every couple of days (which can be a pain the arse). The only other issue with a 10 gallon tank is the fact that once your goldfish reaches its maximum mature size, the tank will offer little room for movement; the rate of waste the fish produces also increases, so you're water changes will have to be more frequent. If you want the smallest and most optimal possible tank for a goldfish, opt for a 20 gallon long tank. Those are around 30 inches long and 13 inches wide. Keep in mind that smaller tanks require more frequent water changes, so most people end up buying a bigger tank because some find it more worthwhile to get a larger tank without having to worry about frequent water changes.
I just wanted to clear that up because many people assume that goldfish need large tanks simply because that's what we are told. Although I'd definitely advise that you get a 30 - 40 gallon tank for a goldfish, it's absolutely unnecessary to get a tank that large if you are consistent with your frequent water changes. I've had friends who've kept their goldfish in 20 gallon aquariums and have stayed alive for over 7 years (they're fish are about 10 - 12 inches long). I asked how their goldfish were able to thrive in such a small aquarium and all they said was, "Water changes."
Xan Beerboy 1)My friend didn't lose his goldfish. If you read my comment, you'd deduce that he had the goldfish since 2007 and it is still alive and well
2) I never said that it'd be optimal to keep a goldfish in a 10 gallon tank the rest of its life. I even stated the issues that would arise if you did, but I won't list them out here seeing that you can go back and read it
3) The size of an aquarium does matter. That I agree, but buying a 30 gallon tank is not needed if you are diligent with your water changes. At the minimum, 20 gallons should be sufficient for one single goldfish. The only reason why any fish would stop growing is because of mediocre water quality. All the nitrates induce stress-related hormones to the fish, stunting its growth. The physical size of the aquarium has nothing to do with it.
Like I said, I'd encourage anyone to buy a larger tank if they can, but 20 gallons is sufficient for one fish.
You could Get something like a 10 gallon and keep a few zebra danios, or a betta as they will interact with you a bit better as far as fish go.
Deh_Nandie Bettas HAVE to be alone. They'll fight with another fish. 10 gallon alone is not enough for a gold fish and you don't want to add more if it's not even big enough for the goldfish. Is HAS to be 20 gallons and you can add anything else.
Is a light an absolute must? is so what would happen in I didn't have one?
You don't need a light unless you also have live plants. For just goldfish light from a window will do but their true color will not be very bright but will cause them no harm.
it stimulates growth and breeding
Are there tanks at local pet stores?
Test tubes are MUCH better. More accurate and will last you longer than test strips and save you more money.
yes just was wondering how long
g it takes the green machine to clear at tank seventyfivegallons
great video. love goldfish
You can put 2 neon tetras in your 10 liters, but be sure its barebottom tank.
Thank you for this video, it really help me a lot. Thanks!
A good tutorial really!But on the begining,about aquarium size,you need at least 50l for one goldfish,because they grow very large!
yes
10l Is a bit small. I live In the United States, So my conversions may be a bit off, but Here the rule Is '20 gallons for 1 goldfish, and 10 gallons for each additional goldfish. That would roughly equal 30l for 1 goldfish, 15l for each additional goldfish
@0:30 .. Theres a fishtank on the far left does anyone know the name of it i want to get one i seen one in a pet shop about a 30 minute drive from my house i wanna see if there good first. Thanks!!
When should I switch of the air pump for gold fish tank
This is wrong. Don’t listen to this guy. Goldfish need a LOT MORE SPACE.
Near a month, if you have natural plants it can be less, but it's better to be patient ;)
Do you need a light if your tank is in a bright room? (Conservatory).
@szaki ammonia and nitrites are fish killers, nitrates build up algae.
I like gold fishes but if I buy them they hardly live for a week and die.I'm taking care of them good.but they die .what to do
One thing, fish don't need tall or round tanks.. It puts stress on them and such..
@coraldude98
Also there is sometimes "good" bacteria in the filter, helping with the cleaning. You will destroy those with tap water.
he also need to cycle the tank..and i dont think goldfish need a stress coat(i dont really know what a stress coat for)..ty anyways,nice vid.
i have an aquarium for almost 2 years the gravel grew some sharp snails is it good or is it bad?
True, but having an aquarium doesn't mean you should get wet. There are many ways to minimize your exposure to water when you own an aquarium.
awesome video! but can anyone tell me how many gallons does it have to be for two fancies??? is 10-20 gallons enough???
I don't have gold fish but i have 5 fish in a 10 gallon tank so you should be covered with a ten gallon
A goldfish needs at least 300 litres aquarium. Bigger is always better. I highly recomment to buy as big aquarium as you can, otherwise leave fish to the shop. A goldfish survives with only one or two goldfish mates, but because it should be kept in larger groups it is good to have an aquarium which size is between 600 and 1000 litres. A tumb rule is 100 litres water for one goldfish. Keep in mind that goldfish could reach to 20 cm lenght.
Nice video, but no mention of cycling the tank before adding your fish. A fishless cycle takes from 4-6 weeks.
This is a really helpful video
more water means the fish waste will polute less the water which means less tank cleaning
Where did ya'll buy this beautiful tanks?
I Have A 500 Galon Freshwater.What Fish Can I Put That Is Big
Reyes Nah silver arowana
+Reyes Nah you have a 500 gallon aquarium and don't know what fish to put in it? Are you sure you don't mean 50 gallons? Because 500 gal is around 2000 litres... it's massive.
is a 10 gallon okay for a black moor? someone please answer because mine is in a 10 gallon right now and i’m considered. it’s only one and it’s a baby
Elyssa No. 10 gallons isn't big enough.
Goldfish actually need to be in a pond not a tank bc they grow SO freaking big! I learned this the hard way.... Good vid tho ;)
I wouldn't go with smaller than a 20 gallon for one goldfish, plus 10 gallons for each additional goldfish. They need the space... Anyone looking to keep goldfish though should check those who keep them and are experienced, via online fish keeping forums, to learn how to best care for them.
The first thing you've got to know in our little hobby is: You cannot keep a normal goldfish in any type of aquarium. Yes they can live for a long time in it, but it won't be a pleasurable life for them. Normal goldfish belong in a pond! Fancy goldfish are a better option. One fancy goldfish needs 10 gallons and must be kept in an aquarium of not less than 20 gallons.
I already know a fair bit about keeping fish but I learned a couple of thinks I didn't already know:)
@fekyalcz depends on your personal opinion, its your tank, you get to decide!
Indeed, that's what they forgot to tell. I do have 4 lovely (young) goldfish in a 40 gallon tanks. And in my eyes it's still a way to small for them. But they are doing totally fine.
try 40 gallons. Common goldfish need a starting tank of 40. Orandas 30 your numbers are a little low but I do agree with which every goldfish there should be a additional 10 gallons though.
0:28 which type of goldfish is that?
@earthy075 i see.. but what u mean the water lik a pond?
Beautiful fish but there is a lot of misinformation in here. Goldfish need a minimum of a 40 gallon breeder
can i put driftwood with my goldfish?
Jean-Michel Gervais Unfornately no as they will ultimately turn the water acidic. Too acidic for any goldfish to handle.
Jean-Michel Gervais Not all Driftwood Affects the phone that much. I have tons in my 55 and the phone is 6.7-7.2 at all times depending on my tap.
the driftwood I would use already been in my aquarium with my goldfish for like 2 month before I put it out for the winter so he could have the chance to releas some tanin. I am exposing him to the elements so he could have some aging and have less tanin, even tho it wasn't bad to begin with... Im also doing regular water changes and I have a lot of rocks in my aquarium... so I guess I could balance the ph and if I find the driftwood make it too acid, i could let the driftwood rest outside and releach some tanin outside before attempting again? also, what is a good ph for goldfish?
10 litres is tiny for one goldfish let alone more... they need about 75 litres per goldfish, then about 30 for every additional fish.
Usually, a few days is not enough time to cycle a tank through the nitrogen 'cycle'. I allow 3-4 weeks before adding any fish. If it's a new tank. YOU SHOULD NEVER rinse filter media AND vacuum at the same time. This can force your tank into a cycle again, because beneficial bacteria is lost. You should alternate your water change one week, and media replacement/rinse the next week. There are flaws in this video.
they're called fluval edge they not big enough to put goldfish in
From what I understand that is not a detrimental amount and perhaps your ammonia converting bacteria are still growing, does your tank have a biological filter so that bacteria can colonize the tank?
Very bad info. Fancy goldfish need a min of 20, recommended 30 gallons per. Commons need more.
Not to mention it is not recommended to get tank kits as they have bad filter with carbon. (You want biological media)
Gravel is not good with goldfish and the cycle is not a few days. It’s months.
I agree fancy goldfish need at least 1.20 tanks with 240 litres or more. They grow huge. Mine were massive while I bought them as tiny fish. In a tiny tank of course because most people get misinformed. I bought a 1.20 tank and they were much happier and healthier. Also, fancy goldfish require an exterior filter ( a very powerful one ) because they crap a lot. You will need to do many water changes. Goldfish are also immensely underfed at most owners. They're amazing fish with great personalities but not for beginners and not for people who wanna stuff them into tiny tanks. Just buy a tropical fish if you wanna keep them in small tanks. Please don't believe the shit you see in these videos! Read up on them first at proper aquarium forums.
