Oranda is one of the most fancy colored goldfish species. Its body length is from 20 to 31 centimeters (8 to 12 inches) long. However, the fish grows that large only if it dwells in open waters. Lifespan is 10-15 years and even up to 20 years provided with good tank or open water conditions. It can be kept in an open pond at the condition of maintaining it clean and with relatively high water temperature (low water temperature is unallowable).
