Goldfish-farming became an important industry and the Grassyfork Fisheries of Martinsville, Indiana, for example, sold up to 20 million fish a year. The Chinese began to breed goldfish a thousand years ago. Beginning with wild fish that sometimes showed a golden tinge, by selective breeding they produced dozens of different varieties with fantastic shapes and glorious colors. Since the beginning of the 16th Century, the Japanese have developed many other new and strange types. Fantails, Veiltails, Fringetails and Comets all have greatly enlarged or distorted tails.
Nymphs have stubby egg-shaped bodies.
