Calico is a color pattern that can occur in many breeds of domesticated goldfish (Carassius auratus auratus). Calico goldfish are usually the following color combinations: red, orange, black, grey, and/or white. This coloration can cover the scales and fins of a goldfish partially or entirely. The color black usually occur in splotches on calico goldfish.
Shubunkin, a calico-only breed, is perhaps the most common and most popular of all calico goldfish. Calico coloration occasionally can also be seen in other breeds such as Telescope eye, Fantail, Ryukin, Oranda, and Ranchu.
