This book is excellent value for money. It covers a very important area in fishkeeping that a lot of people ignore. This book is a must for the inexperienced fish keeper, in fact, I would go so far as to say that this book should be made compulsory to beginners. My only criticism with the book is the fish disease section, towards the end of the book, this should have had example pictures of each aliment, to enable the beginner to accurately diagnose disease in their own fish. Overall an excellent book for the beginner to intermediate fishkeeper and excellent value for money.
