The Calico Ranchu originated in China many years ago. They are one of the oldest types of fancy goldfish to date. In the 1800s, these fancy goldfish were introduced to the Japanese in hopes of further developing the breed.
The Ranchu is highly sought after for goldfish competitions, especially in China and Japan. These fancy goldfish have around and chubby body shape that is similar to that of the Lionhead or the Oranda. In fact, they resemble the Lionhead so closely that they are often mistaken for them. The Ranchu goldfish breed lacks a dorsal fin which is one of the reasons for their restrictive swimming abilities.
The Calico Ranchu has a broad back and tail fins that fan out almost horizontally. The Calico Ranchu Goldfish can come in a variety of colors and patterns. The most familiar patterns are red and white with black spots or gold and white with black spots.
