Koi have been kept for thousands of years through out East Asia, but a lot we have today were introduced from Japan in the 1800s.
Koi attach their sticky eggs to water plants or any object submerged in the water. The young hatch as larvae and stay in warm, shallow flooded areas until they are large enough to brave more open waterways.
Koi are omnivorous and opportunists – they will try to eat anything they think is edible including insects, fish, and plants.
Koi have an average lifespan of 40 years. It is believed that the oldest-known koi lived to be nearly 230 years old; the age was determined by testing the fish’s scales, which produce growth rings much like a tree.
