A detailed guide to the living habits of Five-Color Koi, and how to keep them so they do not die easily
Five-Color Koi are produced by crossing Pale Yellow Koi with Tricolor Koi, and are named "Five-Color" because they carry white, red, black, and indigo on their bodies. Among White Five-Color koi, those with a particularly beautiful red pattern are considered the best. In recent White Five-Color koi, rather than polluting the red pattern with black speckled markings, most show blue emerging on a white base. What is...
Five-Color Koi are not strict about water temperature and water quality, and their living water turbidity range is 2-30°C. Although they are highly adaptable to the environment, they have a weakness: they cannot resist sudden changes in water temperature. If kept under artificial conditions for a long time, they can still tolerate a water turbidity rise or fall of 2-3°C, but when the temperature drops or rises by more than 2-3°C, the fish easily become ill. When the temperature rise or fall increases to 7-8°C, the fish lie motionless at the bottom, neither eating nor moving. If the sudden temperature change is even greater, they may even die immediately. The most suitable living water turbidity is 20-25°C. In water at this temperature, koi swim actively, have a strong appetite, are robust in constitution, and have vivid colors. Controlling the water temperature to the most suitable level for koi growth, so that the fish can have a comfortable environment and grow rapidly, is even more ideal. Golden Koi living in water rely on their gills to absorb oxygen dissolved in the water, sending the oxygen into the fish body where it combines with absorbed food nutrients to produce energy to sustain life. Therefore, whether there is sufficient oxygen in the water is the key to raising fish well. The oxygen requirement per kilogram of body weight per hour is 35 mg/L at a water temperature of 5-6°C. This proves that the higher the water temperature, the greater the oxygen consumption.
