I have had fish before including a Beta who just died recently, there is no problem with how much care or anything but i need to know how to take care of Koi, and if i can raise them in a tank. If i can raise them in a tank how big of one would i need? I only want TWO SMALL Koi. Is a 10 Gal tank big enough? Probably not…….. I really need some help…….
Thanks!





koi reach about 10-12 inches in length, and they need a lottt of swimming room. dont get them, get some guppies or something for a 10 gallon
Koi are really pond fish… sorry…
KOi need to be in a pond 1000 gallon plus you cant keep them in a fish tank!
here a few suggestions to the type of fish you can have in a 10 gallon tank
dwarf gourami
Cardinal tetras
Galaxy rasbora
Guppy
Dwarf corydoras
Dwarf lamprolagus
As the others have said Koi’s are a very large fish. Beautiful but they need a lot of swimming room, nothing short of a small pond or if you can hold a 500 gallon tank go for it. The listed fish from the previous person are nice but I would like to add some much more personable and colorfull fish. I have good experience with Cichlids.
African cichlids are very energetic and colorfull but very aggressive and territorial so make sure to get them when they are young & from the same store, and make sure there are lots of hiding places like rocks and plants. They reach sizes from 2″ – 12″ depending on the type you buy. Tank size should be nothing short of 40 gallon.
For a 10 gallon tank I would say upgrade, but if the cant happen gor for tiger barbs or giant danios, very energetic and love to swim in schools of 3 or more, also would be fine for a 10 gallon tank.
Hope this helps
You’re better off getting 2 goldfish. Koi can sometimes grow up to 3 feet. There’s no way you can keep a full grown koi in a 10 gal. That’s why they bred goldfish for small containers, compared to the needs of a koi.
Koi can easily reach 3 feet long. They are not a fish you can keep in a 10 gallon tank. Koi need ponds, period.
You could get a fish called a shubunkin. They have similar colors to a koi but don’t get as big. You’re still going to need 50+ gallons depending on what you get.
