How To Make Koi Grow Faster


How long does it take a koi to be 12 inches? - Roderick

There are several factors that affect the speed of growth:
  • Genetics
  • Environment
  • Feeding
Some Koi grow faster than others.

There really isn't anything that you can do for this. You can buy from a breeder that has shown fast growth in his fish for several generations and hope that your will have that gene too.

Koi grow faster in large ponds.

Mud Pond
The Japanese breeders grow out their tosai in huge three to five acre ponds that are very deep. These mud ponds are enormous compared to the little garden ponds that most people have. The average Koi person has a pond that is only a few thousand gallons. Not many people have the room or the budget for a large pond in their backyard.

Temperatures affect Koi growth.

Koi do their growing in the summer. The abundance of nutrition and the warmer temperatures accelerates their growth to its maximum potential.

The more you feed a Koi, the faster it will grow.


Koi need high protein food to maximize their growth. Feeding several times a day is a good idea to make your Koi grow faster (just don't overtax your filter system). You'll want to feed your Koi a high quality, high protein food. Just be careful not to over-feed your Koi. You can make your fishes fat and it will deform their body conformation.

In ideal conditions, it usually takes a couple years for them to get about 12 inches in length. If you have a small pond in live in a cold climate, it will take longer. If you have a large pond, feed a lot and you live in a warm climate, then it could take less time. Every Koi is different, some start out as slow growers and then speed up as they get older. Some start out as fast growers, and then slow down after a couple years of age.
