Butterfly black and white scale

This bold koi features a soft cream and golden head transitioning into a dramatic deep black (Sumi) body with silvery-grey marbled patterning across the back and sides. The long, elegant fins are streaked with dark and light tones, adding to its striking silhouette. This fish measures approximately 9–10 inches — a large, mature specimen with a powerful, commanding presence.

Its dark, marbled colouration suggests a Kumonryu or Matsukawabake-type influence — a fascinating variety known for its ever-changing patterns, which can shift dramatically with water temperature and season.
