About
The Tancho is a goldfish with a pure-white body crowned by a single vivid red wen on the head, named for the way its coloring recalls the red-crowned Japanese crane whose head alone is red—a refined and popular variety. A color variant built on the Oranda body type, its very simplicity—white body, red cap—makes the clarity of the red-and-white contrast and the depth, roundness, and clean outline of the red the keys to appreciation and judging. The body is rounded with longer tail fins and the fish swims gently. Clean water is important for healthy wen development and for maintaining the red, with care taken to keep the wen's grooves free of debris. Keep it in a tank of 60 liters or more with strong filtration, regular water changes, and color-conscious feeding. Swimming gently, it pairs well with similarly calm varieties.
