Beni Kikokuryu is a stunning tricolor metallic koi featuring red, black, and silver. Learn about this complex and beautiful variety.
The Beni Kikokuryu is a spectacular and highly sought-after evolution of the Kikokuryu variety. It takes the metallic silver base and changing black (Sumi) markings of the original Kikokuryu and adds a third color: a vibrant red or orange (Beni). This results in a tricolor metallic Doitsu koi that is often considered one of the most beautiful and complex varieties available. The name 'Beni' refers to the red pigment, which provides a stunning contrast to the cool silver and deep black of the base fish.
A top-quality Beni Kikokuryu must balance all three elements: the metallic silver luster, the deep 'Sumi,' and the bright 'Beni.' The silver base should be brilliant and highly reflective. The black markings should be well-placed and possess the same 'shifting' quality seen in Kumonryu. The red markings should be intense, clear, and ideally placed to create a harmonious tricolor pattern. Like the Kikokuryu, the Beni Kikokuryu is a Doitsu variety, so its skin should be smooth and free of stray scales. The interaction between the three colors on a metallic, scale-less surface creates a depth and vibrancy that is hard to find in any other variety. The head often features a mix of all three colors, making for a very expressive and dramatic facial pattern.
The variety was created by Haruo Aoki of Aokiya Koi Farm by crossing a Kikusui with a Kumonryu. Beni Kikokuryu are prized for their rarity and the challenge of producing a koi with high-quality color and luster. They are dynamic fish — the black (sumi) pattern shifts with water temperature and the seasons, while the red stays stable — making them a fascinating addition to any collection. The 'Beni' can range from a soft orange to a deep crimson, and its placement against the metallic silver often makes it look like it's glowing. For the advanced hobbyist, the Beni Kikokuryu represents the cutting edge of koi breeding, combining multiple complex genetic traits into one breathtaking package. It is a variety that demands attention and rewards the observer with its intricate, shifting beauty and unparalleled metallic brilliance.
Keeping Beni Kikokuryu koi in Southern California
These koi change pattern with the seasons. Breeders describe more black in cold water and more white in warm water, and a change can happen within weeks or even days.
In a warm SoCal pond, a Kumonryu or Kikokuryu may show far more white than it did at the farm. That is normal for these varieties and is not a sign of illness.
On a Beni Kikokuryu the red stays stable while the black moves. Breeders value body shape and skin over today's pattern, because the pattern will change.
Summer care for every koi in SoCal
- Warm water holds less oxygen, yet koi need more oxygen as the water warms. That makes summer the season when oxygen runs shortest.
- Oxygen is usually lowest around dawn, because plants and algae use it up overnight. In summer, keep air stones, waterfalls or fountains running day and night.
- When oxygen runs short, large fish are often the first affected. The bigger and faster-growing your koi, the more aeration matters.
- Published "ideal" ranges vary between sources, from about 59–77°F to 68–78°F. Most sources treat the low-to-mid 80s °F as the point where you should cut feeding, add shade and add aeration.
- At about 82°F and above, feed less than usual. Koi can lose their appetite at 86°F and above, so offer small amounts of an easily digested food and remove anything left uneaten.
- Shade part of the pond, but not all of it, from the afternoon sun. A shade sail, pergola or floating plants will do. Don't enclose the surface so tightly that air can't move over it.
- Inland SoCal is much hotter than the coast. NOAA's 1991–2020 normals give an average July–August afternoon high of about 95–97°F in Riverside, 83–85°F in Santa Ana and 75–77°F at LAX (air temperature). Inland ponds therefore need the heat measures above sooner and for longer.
