The subject of Cichlids is a study in complex social behaviors. Although this reference didn't have anything new to say about Cichlids, it is an accurate primer of the most popular varieties from the African Rift Lakes and Central America.
Curiously, what caught my eye is the term "Pet Owner". Cichlids are indeed very much like pets. Strange though it may sound, this species of fishes goes through a bonding stage very early on and the bond continues to develop through the years, so they may watch what's going on outside of their tank and respond to familiarities.
This is a good book for anyone considering the purchase of a Cichlid. It treats the species appropriately so that the reader comes away with a good understanding of the social structure that is so highly evolved within the Cichlid society, without the expense of a more detailed book the reader may not need before they commit to the fish.
The book does not offer much to the advanced aquarist, but it does cover the basics of diet, disease, compatibility and behaviors. The authors are experienced with the species, but offered little by the way of expert advice.
