The author Dick Au (San Francisco, California) has been involved with discus for over forty years. His first experience with discus dated back to the early 1950’s when he observed the first commercial spawning of brown discus while working in a fish farm in the Orient. A well-known breeder of aquarium fishes, he consistently produces quantities of quality discus year after year. He has received numerous awards for contributions to the aquarium hobby as well as lifetime memberships to several aquarium societies. Insisting on keeping discus as a hobby and not as a business, the author spends much of his time giving lectures at aquarium societies, judging fish shows, and writing about discus.
