The book itself is recommended for people who are stepping into the world of cichlids. If you're deciding wether or not you'd like to keep cichlids or deciding on which cichlid species to keep this is the book for you. It covers most basics of cichlid keeping, describes differences between different sorts of these fish. Everything is backed up with great pictures. The book will sure make a lot of influence to your decision on which cichlids to choose. Some most common speciers are described in more detail.
Overall, you'll find basic information on all aspects of cichlid keeping (tank setup, equipment, feeding, breeding, illnesses etc.). However, if you're making your first aquarium, I personally recommend that you buy some beginner guidebook on setting up aquariums. Also, once you choose the kind of cichlids to keep, you'll probably want to buy another book which describes the chosen species in more detail.
This book would be a waste of money for professionals.
Four stars are given because I think that some topics could have been covered in some more detail.
