The Koi is considered to be one of the most popular fresh-water pond fish that has emerged in the fish industry today. The Koi can be seen living in the waters in lots of outdoor ponds throughout the world. They are well-loved by enthusiasts due to their various colors and patterns and the longevity of their lifespan (up to around 30 years). Such qualities make them the perfect pets to be taken care of in ponds.

The Koi are domesticated types of the carp (the word "Koi" is Japanese for "carp"). These fish come in a wide array of colors and patterns, like orange, black, yellow, red, blue, green and silver. External elements like the environment where they live in and the kind of diet that they have will affect their color, and with this here you can see the amount of skill and patience it took for the first breeders in Japan to develop such an amazing fish!

They are very social with the other breeds of fish, as long as they are not small enough to be fed upon by those large opportunistic predators. In smaller areas they tend to school together, but divide into smaller groups in larger areas.

They can grow very long, so you're going to need at least 500 gallons of water to contain them. As you decide to house your fish in smaller ponds, also consider as to how big they can get. If you ever reach the point of overcrowding, you can change the size of the pond completely making it bigger, or choose to give your larger fish away for smaller ones.

As space is important for your pet's health, remember to keep the number of fish you have in the pond with respect to the amount of water held by the pond. Because they cost much, they can be hard to replace with.

They thrive in cold water tempertures between 61 and 75 degrees Fahrenheit. Because these amazing fish live in cooler temperatures, they can be kept outside in the winter safely. Make sure that the pond itself will reach no less than a depth of 3 feet. As winter time comes, they will begin their hibernation. Their digestive system will then slow down as if almost stopping. The food in their stomach may turn rancid that can make them ill, that's why it's very important not to feed them when temperature falls below 50 degrees Fahrenheit.

The pond itself is a soothing area as you hear the rippling water flow, and to make it complete, it should be added with fish as magnificent as the Koi. Owners throughout the world think of themselves as lucky having this kind of magnificent pet they can take good care of everyday, touching their lives in a very special way!
