It proved impossible to present all the animals suitable for an aquarium in one volume. Therefore, we presented certain fish families, such as the surgeon-fishes and wrasses, as completely as possible, since there is no complete reference of them. This means that even fishes unsuitable for an aquarium are included, but they are clearly marked as such. However, the taxonomist will enjoy their listing. The great majority of the pictured fishes can be housed with invertebrates. The crustaceans and the anthozoans are presented here. In the plant section, W. A. Tomey from the Netherlands presents an elaborate treatise on a great variety of Caulerpa. Since these higher marine algae are an almost indispensable part of the biological cycle and green decoration, the chapter on marine algae is quite extensive. We strove to present the technological and chemical aspect of the marine hobby at today's state-of-the-art-level and to entice the reader to try new methods following the newest trends. 1216 pages, full color photography, 600 marine fishes feeding, breeding and natural history, 450 invertebrates and plants.

Nudibranchs & Sea Snails
Indo-Pacific Field Guide
by Helmut Debilius

1998, IKAN Publishing Frankfort Germany, 2nd edition, hardcover with stitched binding, about 5½ by 9 inches (about 14 by 22 cm), 321 pages, full color photographs of more than 1000 marine molluscs in their native environment.

This is a beautifully illustrated  photo guide book that contains over 1000 full color photographs of marine molluscs. from the Indo-Pacific region. As is the case with the other guides done by this author the photographs are phenomenal.
The shell-less molluscs make up the greater part of the book but there is also a section of about 120 pages of photos and descriptions of those molluscs that have shells and probably the ones that you are most familiar with. Even though these shells are familiar it is still quite an experience to see the living animals  through Debelius' camera lens. It helps reinforce the idea that there is a lot more to the shells than the shell itself. This is an excellent book and one that is in brand new condition. It is also not an easy book to obtain.

With more than 6000 photographs of marine fishes this book sets a new benchmark for their identification. It provides the greatest possible coverage and is aimed primarily to assist people interested in marine fishes and their scientific names or classification. 
Presented here are the fishes one is likely to see when diving or snorkeling in the sea, as well as those that are traded in the aquarium industry. This World Atlas includes both tropical and temperate fishes. 
Depending on the size and popularity of the groups or families, introductions to these provide general information, distribution and habitat, number of species, interesting facts on behavior and aquarium suitability. In the case of very large families like wrasses, damsels or gobies, separate introductions may be dedicated to each distinctive group or subfamily. 
The greatest possible number of photographs is used on a page, but in sizes that clearly identify the fish. Variable species may be illustrated with more than one picture. In all, included are some 4,200 species. 
This is an invaluable reference book for the great variety of marine fishes found in the world’s seas. As such it addresses all fish enthusiasts - divers, snorkelers, fish watchers, fisherman, reef surveyors, aquarists, ichthyologists and bio-geographers.
