This is an excellent guide for the novice fishkeeper, it contains all the information that you will need to know about what type of fish to buy for the aquarium. It advises whether the fish are ideal for the novice or a more experienced keeper, what water type the fish prefers (acidic, neutral etc), the correct water temperature, the size the fish will grow to, the minimum number that you should purchase as not all fish will live in groups some are solitary whilst others will only live in shoals.
The book contains a basic guide to understanding your fish and how to take care of them to building a compatible aquarium. This book has been invaluable in deciding on which fish to purchase has I have learnt the hard way and lost a lot of expensive fish by buying fish that were for the more experienced keeper because they looked very nice, believe me its not worth it, follow the guidelines in the book. After reading through the book, choosing fish suitable for the novice, I know have a well stocked tank and all is going well.
