All About Koi Fish and Goldfish

If you are someone who believes that a water garden isn’t complete without Koi fish or Goldfish, you are not alone. Whether you keep fish for practical reasons like mosquito control or for their bright shimmering colors, fish are an important addition to a pond. You might even think of them as pets and give them names. No matter what your reason it is important to keep your pond healthy and functioning properly in order to maintain the well-being of your fish.

Koi fish are descendants of the common carp. In nature they are actually brown, but through selective breeding by the Japanese, many colors and patterns were developed. In the 17th century Chinese rice farmers began keeping carp in their rice paddies. This practice found its way to Japan where rice farmers began to notice slight color variations in a few of the carp and bred them into what eventually became what we now know today as Koi. It wasn’t until early in the 20th century that Koi left Japan and were raised in Europe and eventually North America.

Koi usually reach up to 2 to 3 feet in length and weigh up to 35 lbs. Because of their significant size, they should only be kept in large ponds. Koi that have been well cared for have a life expectancy of around 50-70 years and have been known to live to be over 200 years old. Koi need very good water quality to remain healthy. Good quality pond filters should be used to maintain the water.

Goldfish are the most popular choice of fish for a water garden and are well suited for almost any pond size. Goldfish can live many years and are found in a number of varieties and colors. Through selective breeding over the centuries there are now many classified varieties of goldfish.
