Question

Can I put koi fishes in a 20 gallon tank I have at my apartment, if so how many.?

Answer 1

MAYBE one, no more-



Have you ever seen those big goldfish looking fish that they keep in fountains and small ponds? Well, they get to be a little over a foot long and average about 8-12 pounds- they get BIG.



If you like the look of Koi, but don't want the hassle of a fish getting too big too quick, try a shibunkin- they are the fancy little Japanese goldfish with the really pretty tails and the calico coloring of a Koi.



Even a 50 gallon tank would be too small for a Koi, and it would need a 150 gallon tank before too long. (And it might even outgrow that tank, too).



Taking in a fish because the owners don't want it or can't take care of it anymore is a bad idea- don't take on their problems just because you want to be nice- you'll hate yourself for it.



Hope this helps :)

Answer 2

koi need about 2/3 gallons of water per inch of body size including tail. They grow very fast, and will reach 24 inches in length.I would leave this species for the ponds. If i were you i would consider a tropical tank with tetras or a livebearing tank. The size of the fish will be appropriate for the size of the tank. Goldfish Usually do better in much larger tanks, but if you only but one fish in you could pick a regular gold fish or one of the fancy varietys to put in there, just keep in mind a full grown goldfish at 10 inches needs a min. of 20 gallons so i wouldnt put more than one fish.

Answer 3

No more than one large koi in a 20 gallon, and eventually you would need a larger tank. The standard is one inch of fish for every 2 gallons of water.

Answer 4

Koi do better in a pond, I would recommend fancy goldfish instead, like Orandas, Ryunkyns, Shibunkins, or other similar fish, they are just as sought after in japan like the Koi, and the colors and variations are similar to Koi as well. You can have more of them in a 20 gallon, a few fancy goldfish are prettier than one Koi.

Answer 5

None. Koi really do not belong in tanks unless you want to get a very large one (we are talking about more than 150 gallons and even that could get too small).



Koi require lots of room and do very well in big ponds (that are well maintained).



If you want to stay in the carp family, you can have 2 comet goldfish. These are your common/feeder fish. They require about 10 gallons each as they can grown huge and are very messy.

Answer 6

The rule of thumb that i have heard is one inch of fish per gallon. However with more aggressive fish they would be less stressed with more space because they are territorial and desire space for breeding. koi are not an aggressive species of fish and can abide by the rule of thumb. Remeber to account for the growth that your fish will experience. They may be way over crowded in 6 months in your get too many now.

Answer 7

koi fish are not cheap and they usually live in very clean and filtered ponds. this is becuase they grow very big and the tank you have would not be enough for one koi when it start to grow. maybe you should look at coldwater fish or tropical fish.
