Fish veterinarian Dr. Johnson writes extensively on goldfish health and disease, including microscopy techniques, diagnosis, treatment, and prevention of the full span of goldfish diseases. In a helpful and accessible "frequently asked questions" format, Richard Hess provides a general introduction to all aspects of the hobby, from selecting the best fish, aquarium setup, maintenance, feeding, sexing and breeding, and keeping fish healthy. Jackie and Louis Chan, major exporters of fancy goldfish from China, discuss the tradition of goldfish appreciation in China, and a chapter on Japanese goldfish describes the history and standards of uniquely Japanese varieties and the techniques and secrets of Japanese breeders. Izhak Kroshinsky, a leading breeder of Ranchu in America, describes his methods for cultivating a superior strain over the last twenty-five years. With over 100 color photographs of beautiful specimens and rare varieties by Fred Rosenzweig, this book is a stunning visual reference as well.
