This guide includes all of the species likely to be encountered by scuba divers and snorkelers exploring Fiji's reefs. It includes 866 species from 92 families, with over 1,200 photos. Each form is shown of fishes where males and females, initial phase and terminal phase look different. Fishes are shown in taxonomic order, the way naturalists and scientists expect them to be listed. When a species is likely to be confused with another, the differences are pointed out. All photos are of unrestrained live wild fish in their natural habitats.
