Koi fish are always at ease in the water, flowing as the tide runs deep under water. Feng shui, a spiritual form of organization and placement of objects, says that having the spirit of the koi near you will attract good luck, fortune, and spiritual benefits.
Koi are omnivorous, meaning that they eat animals and plants. If you decide to keep these fish, you can feed them certain plants, snails, and worms. Generally, they are bottom feeders and sift through the muddy substrates on the bottom of a pond for food, but commercial fish food is available that has a mixture of morsels. Some components of the food sink and some float so that you can encourage the koi to come to the surface of the water to enable you to monitor their physical health.
Koi can grow up to 120cm in length but usually average around 60cm. Their size is dependent on the quality and temperature of the water they live in, genetics, the capacity of their home, and the type of food they consume.
These hardy fish adapt well to different temperatures, but their immune systems can be compromised when the water temperature drops below 10 degrees Celsius. In order to thrive, they need their habitat to be 15-25 degrees. The pH of the water is important to monitor too. Although koi can tolerate a pH range from 6.5 to 9.0.
