Aquarienfische und Wirbellose

Schaefer, A Jacket-Pocket Compendium of Aquarium Fishes. More than 250 profiles provide a comprehensive overview of the most popular aquarium fishes and invertebrates, covering significantly more than the standard range of every specialist pet shop.
If you can't find exactly the same species, it is perfectly acceptable to choose other species of the genus in order to gain an idea of the fishes' requirements. Pictograms and symbols in each profile help you make this comparison at a glance. The book also contains a brief description of the individual fish families and groups prior to the main section.
