They are also quite vulnerable to pH changes and should not be exposed for long periods to overly acidic or alkaline environments. Pearlscales are very sensitive to cold water and should not be exposed to temperatures below 55☏ (13☌). Like many fancy goldfish, Pearlscales are egg-shaped with internal organs crowded in a compacted body, therefore overfeeding should be avoided. The bubble-domed Pearlscales are known as High-head Pearlscale, Crown Pearlscale or Hama Nishiki. Pearlscales are found without headgrowth ( wen), with Oranda-like headgrowth, or with two large bubble domes. Calico fish should have a blue background with patches of violet, red, orange, yellow and brown, spotted with black.Ī young Pearlscale before wen development Variants Metallic colors should appear as burnished metal, extending into the fins. The Pearlscale may also be fully black in color. The color may be metallic (ideally self-colored or variegated in a pleasing pattern and similar on each side), orange or calico.

To be able to add them to your goldfish tank, they must also have the same diet and water temperature needs as your goldfish. Quality fish will have high color intensity extending into the fins. The caudal fin should be held high without signs of drooping and well divided. The body should be short and rounded (not elongated). The oranda was derived by crossbreeding the veiltail with the lionhead goldfish. It can grow to a length of 8 to 12 inches.

Dorsal fin to be single, all other fins to be paired It is a cross between an oranda and a telescope-eye.Depth of body to be greater than 2/3 of body length.The Pearlscale can also known as the Ping Pong Pearlscale and Golfball Pearlscale. This is attributed to the selective breeding process of fancy goldfish to achieve particular body forms, such as that of the Pearlscale's roundness, which results in the alteration of the appearance of the shape and function of the swimbladder. Pearlscale goldfish are susceptible to swimbladder disorders which affect the ability to maintain normal position in the water. Pearlscales can reach up to 8 inches long and grow up as large as an orange. This variety can be a bit confusing and makes people think they are different species. Its body is round and similar to a golf ball. The characteristic feature of the Pearlscale is its thick, domed scales with pearl-like appearance.
