There's only one way you can keep koi in a aquarium, and that's keeping any koi under 4-5" in a tank no smaller than 30 gallons (per koi). That will last for 3-5 years, then they need to go in a small pond minimum, whether in or out door. If you keep a koi in a aquarium for too long they will get health issues and croak. That's a promise, they won't make it. If you want to keep an aquarium just keep fancy goldfish, but a koi will eventually have to go into a small pond, they need the ecosystem and area, for they produce a ton of waste.
Last year I put 100 baby koi from cuttlebrook in a 4feet tank all when really good aerated and heated tank 25 degree good growth through winter and in the spring up them in small 2000 litre pool all doing great , I've just ordered another 100 from cuttlebrook this ,we really enjoyed growing them on ,the first lot of koi will go in big main pool for winter 10k pool 6feet deep
Nice that’s a really smart tactic to grow on fry I do that as well keeping them in a tank over winter usually helps them grow a-lot faster glad to here that it all went well with them.
Do you think I could get away with two 7.5 inch koi in a 100-150 gallon tank for 3 months? Just until spring when it’s warm enough to put them in my pond. What’s the smallest tank size you’d recommend for this scenario?
yes thats more than enough. Keeping koi in aquariums imo is totally possible and it's very common in Japan for example for the casual koi keeper (not everything is a mud pond over there). Key things will just be: not overfeeding, good filtration, and a neutral water temperature of not too cold but not too warm, 72-74F is a nice middle spot.
I have a 4 inch butterfly koi in my 1200 liter pond how long will take roughly to out grow the pond cuss I have seen a really mixed view on how fast they grow and will I need to upgrade the pond if so how long till I would have to. Or as I have seen on some websites it says they release a hormone to stop growing is this Oki for the fish of so how big till it would do this thanks love your video
Hey I’m wanting to get an Aqua Dream 200 Gallon Tempered Glass All-in-one Aquarium White and Silver. So I’m wondering if I could keep 2 koi happy in a aquarium like that? If not I may just get one koi, some comet goldfish, and 5 or more barbs.
I've got two koi a comet and a gold fish for more than a year, the koi isn't really growing and now they just lay down at the bottom of the tank, tank size is 160 liters.
I have a baby koi like 3in how big should I keep it in I have it in a 3 gallon tank rn getting a bigger one but how long do you think till I need a pond
You need 250 gallon per koi. So no. When they are small of course you can fit 3 but they will grow stunted and unhealthy and die after a few years. Kois need a depth of 3 feet min, 4 feet ideal, to get the right water pressure to grow properly.
How many fish do you have together, when you have smaller number they tend to be far more scared and less active. Alternatively some fish are just far less active due to their genetic.
Is over-wintering for about 3 months in a 75 gallon ethical for 2 koi who are about 4 inches? I don’t want to abuse my fish but I’m unable to dig a deep enough pond until next year.
Hi I’d say that I’d it is only 3 months then it may be ok. Although I would say just keep an eye on how large they get. If the water quality is gd then the only side effect you could face is stunted growth but if it is only for 3 months then there should be no issue
I have had no issues with this but I recommend that you only do this if the koi are a similar size to the clown loach. Do remember you can only leave the koi in the tank for just under a year before they get to big

I raise all my fry to 5 inch in my lounge aquarium never had any problems and i love having them in the house
I am getting a 8 inch Sanke just 1, is a 55 gallon tank big enough for just the 1 when it grows?
Great video 😊 our angels look alike
Thank you
I have a question. Can I put another kind of fish in a koi's acquarium? Is it dangerous for koi or not?
How big is your aquarium?
I’m planning on doing it temporarily when I move to a new house in cape cod.
I’m planning on installing a pond at the new house eventually.
Sounds good keeping them in a tank temporarily should have few issues hope the new pond goes well 👊

Potentially although I would recommend that you purchase no more than two koi for the tank 👍
I've got two koi a comet and a gold fish for more than a year, the koi isn't really growing and now they just lay down at the bottom of the tank, tank size is 160 liters.
It may be to do with the fact that the tank is to small for the koi. Also the water parameters may be off .
160 litres is too small to raise bro
what size tank would you recommend, im only using it to grow on smaller koi and sturgeon until they go in my pond
Definitely something over 100 gallon
How many gallons is that tank
I have a baby koi like 3in how big should I keep it in I have it in a 3 gallon tank rn getting a bigger one but how long do you think till I need a pond
I would get a pond or a bigger tank as soon as possible as it will quickly out grow this tank
what temperature do you keep them at?
Around 23-24 degrees Celsius
is 71 gallon aquarium tank sufficient to grow 2 koi?
Probably not,if you just bought it and it is small.then it is fine.but be ready to switch it to a bigger tank/pond in a few weeks.
I’d follow the advice given by cubation it suitable for only a short time
What filtration and air pump best for budget
sponge filter
So would a 100gal work for at most 3 koi ?
You need 250 gallon per koi. So no. When they are small of course you can fit 3 but they will grow stunted and unhealthy and die after a few years. Kois need a depth of 3 feet min, 4 feet ideal, to get the right water pressure to grow properly.
I want to have a butterfly koi in aquarium I have 50 gal tank can i put 1 or 2 butterfly koi in there?
No
No I wouldn’t recommend it
My koi are not as active as yours any tips i keep the water in proper conditions and around 24 degrees Celsius
How many fish do you have together, when you have smaller number they tend to be far more scared and less active. Alternatively some fish are just far less active due to their genetic.

koi with clown loach? i want to do that but i am scared
I have had no issues with this but I recommend that you only do this if the koi are a similar size to the clown loach. Do remember you can only leave the koi in the tank for just under a year before they get to big
I've done that and it works well 😊
@@UkKoiFish what temperature do you keep them at?
@@Tylertheman7363 at 23-24 degrees Celsius
