Thank you for viewing. This book, published in 1995, features 500 species of ornamental fish from around the world, all in full color. It provides detailed information including family name, scientific name, other names, habitat, points to note, size, and descriptions of the fish. Tropical fish, river fish, goldfish, carp, and saltwater fish are included. I purchased this book new and have read it many times. While there is some wear and staining, there are no particularly noticeable stains that would hinder reading. Please check the photos and understand that this is a used book and an old item before purchasing. Thank you.
