The Pompon or Pom-pom, is also known as the hana fusa, and is characterised by the bundles of loose fleshy outgrowths between the nostrils, on each side of the head. With a similar body shape and finnage to a Lionhead (without the obvious wen growth), the extent of the nasal outgrowths, which are enlargements of the nasal septum, vary in pompom goldfish. In some, the outgrowths hang down past the mouth. These skin outgrowths around the nostrils of pompoms have been developed through selective breeding. Pompoms may have either metallic or nacreous scalation.
The Chinese refer to this variety as the “Velvet ball”. There are records for the existence of this fish being seen as far back as 1898. The first importation of these fish into the United Kingdom was in 1936 when the original fish were exported from Shanghai and others were displayed at an aquarium in Paris. It was quite popular in the early days of the fancy goldfish, but is now very rarely seen for sale or on display.
