The colorless goldfish is the panda goldfish variety. According to the relevant information, the panda goldfish is named because of its body color distribution that resembles that of a panda: its body is short and round, its tail fin is butterfly tail-shaped (common dragon eyes are also called pandas in the same book), and its whole body is silvery white. That is, there is no color. The head, eyes, pectoral fins, pelvic fins, anal fins, dorsal fins and tail fins are all black. There is a black band extending from the dorsal ridge on both sides of the body. Some eyes have white circles around them, which are clear black and white. It looks very much like a cute panda and is one of the most popular goldfish species in recent years. Panda Dragon Eyes are selected from excellent individuals of black and white butterfly tails and targeted breeding. However, their genes are still unstable and can easily fade if they are over 2 years old. Fish with clear black and white boundaries and no signs of fading can be called Chinese treasures.
