It is a very good book with a lot of new information and pictures. You can get an index by contacting Tetra Press who I believe is publishing the new edition. The book is worth the price and if you have ever had the opportunity to ask Paul Loiselle about the problems in getting the book published with or without an index you will understand and be entertained. He is an excellent speaker and writer and I have thoroughly enjoyed his lectures, casual conversa- tions, and reading his books on cichlids.
