Pearlscale Goldfish are very popular and can be found in collectors' tanks throughout the world. Their hardiness and ability to live in cold temperatures make them ideal pets. Instead of having the long, slender body of the Common Goldfish or the Shubunkins, the Pearlscale is one of the more rounded or egg-shaped fancy goldfish. They have a straight back with a swollen belly, resembling a golf ball.
The Pearlscale Goldfish is usually twin-tailed with a very compact body. It can be easily recognized by its nacreous scales that have raised centers and dark perimeters. Arranged in rows, these distinctive scales look like pale pearls.This is the only variety of goldfish with these types of scales. The Pearlscale Goldfish can be found in all kinds of colors, including red, blue, black, calico, chocolate, and red/white combinations.
These are one of the newer varieties of fancy goldfish. The first known mention of them is from the early 20th century. They have been developed largely in England where they first appeared in 1900. Today, there are more than 125 captive-bred fancy goldfish varieties.
Crown Pearlscale Goldfish
A variation of the common Pearlscale is the Crown Pearlscale or Hamanishiki Crown Pearlscale, which develops a hood or head growth similar to that seen on the Oranda Goldfish.
Pearlscale Fancy Goldfish are fairly hardy and can be successfully kept by beginners. However, they must be handled with care as they can be easily damaged. Their scales can fall off with rough handling or after contact with sharp objects. Like many of the egg-shaped goldfish, they are slow swimmers. These fish won't win any races, but if kept with other slow-moving varieties, they should get plenty to eat and do well. Many of the elongated goldfish varieties like the Common Goldfish, Comet Goldfish, the Shubunkin do not make good companions for the Pearlscale Goldfish because they are fast swimmers and too competitive during feeding
Good tankmates are similarly shaped goldfish that are also slower swimmers, such as the Fantail Goldfish, Ryukin Goldfish, and the Black Moor Goldfish. These varieties all tolerate temperatures a few degrees above freezing, as long as the cooling drops only a few degrees a day.
Their hardiness and ability to live at colder temperatures make them ideal for outdoor ponds. If you wish to keep these fish in a pond, make sure the environment is safe. In a warmer, well-maintained tank, even the less hardy Water-Bubble Eye Goldfish, Telescope Goldfish, and Celestial Eye Goldfish can be good companions.
