A ryukin with red-white-black tricolor (calico) pattern. Popular for gorgeous coloring and round body.
The Calico Ryukin combines the Ryukin's characteristic high shoulder hump and deep, rounded body with the vibrant nacreous calico coloration—a mosaic of red, white, black, and blue-green tones across semi-transparent scales. The combination of the Ryukin's bold profile and the richness of calico coloration makes this variety one of the most visually dramatic goldfish available for side-view appreciation. Each individual has a unique, unrepeatable color pattern, which makes the breed popular with collectors. Care follows standard Ryukin practice: tanks of 45 liters or more, stable water temperature of 18–25°C, and regular water changes. Calico Ryukin have healthy appetites and should not be housed with timid slow-moving varieties. Color can be enhanced with appropriate lighting and color-enhancing foods. The translucent scales are sensitive to physical damage, so avoid sharp aquarium decorations.
