Budo Goromo Koi feature stunning grape-colored patterns on a clean white body. Discover the mystery behind their unique coloration.
The Budo Goromo is a rare and striking variant of the Koromo group, named after the Japanese word for 'grape.' While its cousin, the Ai Goromo, features a delicate blue edging, the Budo Goromo possesses a much heavier and darker coloration that gives its patterns a deep purple or maroon appearance, reminiscent of a cluster of grapes. This unique color is actually a result of deep indigo or black pigment being layered so densely over the red scales that they merge into a single, rich tone. The white skin of a Budo Goromo must be exceptionally bright and thick to provide the necessary contrast for the dark, 'grape' patterns to stand out. Unlike the Ai Goromo, where you can see individual scale outlines, the Budo Goromo's pattern often looks like solid blocks of dark fruit. These fish are incredibly dramatic and are often the most talked-about koi in any pond. The challenge for breeders is to ensure the purple color remains stable and does not turn into a muddy black as the fish grows. It requires a delicate genetic balance inherited from its Asagi and Kohaku ancestors. A high-quality Budo Goromo will have a balanced pattern that does not overwhelm the fish's frame, with a clean head and powerful movement. Because they are less common than Ai Goromo, they are highly prized by collectors who want something truly unique. When swimming, the deep purple tones create a regal and mysterious presence, offering a color palette that is almost entirely unique in the world of cold-water ornamental fish.
Keeping Budo Goromo koi in Southern California
Asagi, Shusui and Koromo need the same summer oxygen, shade and feeding care as every other koi (see below).
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.
