The aim of this book is to help aquarists recognize signs of illness so they can identify and resolve problems. Divided into three sections, the first focuses on health and husbandry, describing the signs of a healthy fish, anatomy and general care; the second provides signs of diseases and health problems and is cross-referenced to section three, which covers the treatment of diseases and health problems. Illustrated throughout with top-quality color photos, the book is an invaluable reference for novice to experienced fishkeepers.
