![]() ![]() These specimens then spent the first few years in their silver bronze wild colour state.Īnother feature is how quickly do goldfish lose their black colours? Once the onset of depigmentation begins, some specimens lose their black very quickly, while others took some years for the black to fully disappear. On the other hand, the Black Moor (Demekin) telescope eye goldfish has these four genes in the recessive state, denoted as dp1dp1dp2dp2.Īlthough not quantitatively or qualitatively examined, it is suspected that those goldfish which depigments in a few months after birth contain all four genes in their dominant state, while specimens which depigment in a few years after birth contains only one or two dominant gene out of four depigment genes in its dominant state, resulting in the delay in the onset of depigmentation. Thus, large specimens of black and white Panda Goldfish which retains the contrasting black and white colours do commend high prices and deservedly so.īlack colour and depigmentation in goldfishīlack is not a stable colour in the goldfish, as goldfish has four genes which governs the de-pigmentation, in its dominant depigmentation state, is denoted by Dp1Dp1Dp2Dp2 by T Kajishima in 1977. Nevertheless, the 'problem' with the Panda Goldfish is that the fish loses its black as it ages, some in a few months, others in a few years. Since the development of the Panda Goldfish, black and white oranda, black and white fantails and black and white bubble eyes have appeared as new goldfish varieties. The blue metallic goldfish will be subject of another blog when I have the time. There are a number of colour/shades in the Chinese blue goldfish Chin wen or Lan Yu, examined scientifically by SC Chen in 1934. Similar to the Panda is another Chinese variety called 'Magpie', which is basically a deep blue and white telescope eye goldfish. White ventral and pectoral fins mean the goldfish specimen is at an advanced state of depigmentation, and it won't be long before the fish loses all its black.įrom what I read, the Panda Goldfish was first developed by the Fujian Agricultural Institute/Centre back in China in 1987, and it received 1st price the country's national Fauna/Flora show in 1989. In choosing Panda Goldfish, always choose those specimens with black fins, ie, black pectoral, ventral and anal, and not just black caudal and dorsal fins. Panda is named for its black and white colour, and is always characterised with white abdomens and black backs and tail fins, as depigmentation in a goldfish, ie, losing its black (see below) always occurs from the abdomen and ventral fins first, that is from the bottom half of the fish, moving upward in the fish until the back beneath the dorsal fin. For an image of Panda Goldfish, please see: The Panda Goldfish, nick-named Panda Moor, is a telescope eye goldfish (metallic scaled), which is named for its contrasting black and white colour.
