With many things in life, the question is not always quantity but quality. But when it comes to keeping Koi, the general rule that applies is that the big Koi is better than a small Koi. A fish that has been kept as pets in outdoor ponds for hundreds of years, breeding big Koi is one of the challenges that many Koi owners undertake. If you want to have your own big Koi, here are the things to remember.

Food

There are many factors that contribute to the growth of the big Koi. Serious cultivators of large Koi often take years of breeding in order to arrive at. However, if you are only beginning in your quest for the greater than average Koi, the first thing to keep in mind is that food is the leading factor to Koi growth. Koi will eat as often as you feed them, leading to their immense growth. Food quality, however, matters as well. In general, feeding your Koi with pellets that contain 40 percent protein is the best way to go.

Density

Another important variable to consider when aiming for a large Koi is the density. One of the fundamental issues that fish keepers deal with is the issue of population size. With Koi, plenty of water is best, since these fish thrive in environments where fish density is low. The density largely affects the growth rate of the Koi since lesser density will minimize competition between the fish for food. Plenty of water and low fish density also fosters better water quality leading to healthier and faster growing Koi.

Environment

While small Koi can be kept in large indoor tanks, when it comes to breeding big Koi, the pond is the best solution. The pond, however, is not the only variable to consider. Koi also grow best in water that are warmer, although Koi are generally cold blooded and can live in colder climates. The ideal temperature for optimized Koi growth is 27 degrees Celsius. As with all other fishes, aeration and filtration are also important factors to consider when providing excellent fish environments suitable for growth.

Genes

For serious Koi owners who want the best potential for achieving the ideal big Koi, looking for fish that have undergone husbandry optimized for large size should also be considered. You may know someone who actually breeds big koi, apart from inducing growth spurts through food, density, and environment manipulation.

Stress reduction

Finally, you should also consider the stress levels that a koi may experience. Too much stress can lead a Koi to develop poorly. Among the leading causes of stress for Koi is the presence of an alpha Koi, which sometimes occurs when a population in a pond experiences uneven development and a particular big Koi outstrips the others in growth. These dominating Koi can bully other fish and prevent them from eating as much as they want for optimal growth. Dominant Koi also occur when a new and larger fish is introduced into a pond of younger and smaller Koi. By dealing with these issues, however, it is possible for you to grow a pond of big Koi yourself.
