Regarded as the first and last word on fish health for the pond fish hobbyist, in this second edition, every page has been updated and improved. After losing more than 70 pages of older information, the book still expanded from the first editions' 160 pages to over 200 pages. This book is written in a conversational tone and meant to be understood and applicable to the beginner and advanced hobbyist alike. Well-reviewed by consumers and peers, this book is written authoritatively by a veterinary practitioner with 20+ years treating fish.
