METALLIC KOROMO – LUMINOUS “ROBED” ELEGANCE WITH RETICULATED DETAIL

Breeders Specalizing in Metallic Koromo: 

Marushin

Metallic Koromo koi combine the refined beauty of traditional Koromo with a shimmering metallic sheen that elevates their visual impact. The word Koromo means “robed,” referencing the delicate blue or black lace-like reticulation that overlays the red (hi) pattern. Developed in the 1950s from a cross between Kohaku and Asagi, Koromo carries the clean white base and red pattern of Kohaku, enhanced by intricate netting across each red scale. In Metallic Koromo, that layered detail is paired with reflective skin that glows in natural light.

Major Koromo varieties include Ai Goromo with soft blue reticulation, and Budo Goromo with deeper grape-toned overlay. In high-quality specimens, the reticulation appears only on the red pattern and never spills onto the white skin, preserving a crisp, organized appearance. The metallic influence adds brightness and depth, making these koi especially eye-catching in both ponds and show settings.

Metallic Koromo are calm, hardy koi that thrive in clean, well-oxygenated ponds with ample swimming space. With proper care, they can grow between 24 and 30 inches. As they mature, the blue or black shading often deepens, enhancing the layered contrast that makes this variety so distinctive.
