One of the best Reef Fish ID books for the Caribbean and Florida area by Paul Humann and Ned DeLoach.
The 4th edition is packed with amazing marine life photographs of 683 species and enough information to keep fish watchers busy for years. The book includes the latest information on what is known about the taxonomy and distribution of Caribbean reef fishes. The easy-to-use, quick reference format makes it a snap to identify the hundreds of fishes sighted on the reefs, sand flats, grass beds, surf zones and walls of Florida, the Caribbean and Bahamas.
The fish ID books by New World Publications are really great!! I have never been let down, I can always find what I'm trying to identify!
