Koi fish are one of the most popular ornamental fish worldwide. Their stunning colors, calm demeanor, and longevity make them a favorite among pond enthusiasts. However, keeping koi requires knowledge and commitment. Let’s explore their lifespan, care requirements, and some of the most famous koi varieties.
How Long Do Koi Fish Live?
Koi fish are known for their impressive lifespan. In optimal conditions, they can live for 25 to 35 years, and some have even been recorded to live over 100 years. The oldest known koi, named Hanako, reportedly lived for 226 years, proving that proper care can significantly impact their longevity.
Essential Koi Fish Care Tips
To keep koi healthy, here are some important care tips:
- Provide a Large Pond – Koi grow large, often reaching 24 to 36 inches, so they need at least 1,000 gallons of water per fish.
- Maintain Water Quality – A good filtration system, regular water changes, and a stable temperature (ideally 65-75°F) are essential.
- Feed a Balanced Diet – High-protein pellets, vegetables, and occasional treats like shrimp or worms support their growth and vibrant colors.
- Monitor for Diseases – Koi can suffer from infections, parasites, and stress-related illnesses. Regular health checks help prevent problems.

There are many types of koi, but some of the most famous include:
- Kohaku – White koi with red markings, one of the most classic varieties.
- Taisho Sanke – White koi with red and black markings.
- Showa Sanshoku – Similar to Taisho Sanke but with a black base.
- Ogon – Solid-colored koi, often gold or platinum, symbolizing wealth.
- Shusui – Blue-gray koi with red patterns along the sides.
