Scats, monos, archerfishes and puffers are all standard fare in the aquarium trade. Their splendid colours and their unusual appearance persuade many aquarists to buy them. For long-term good health all these fishes require the addition of salt to the water to create so-called brackish water, but if we search the literature for information on the setting-up and maintenance of brackish-water aquaria, our quest is usually in vain. This book will thus fill a gap in the aquarium literature, as it is devoted exclusively to the subject of the brackish-water aquarium. It portrays in depth the special characteristics of the brackish-water zones of our planet, describes the equipment required to run a brackish-water aquarium, and details how such an aquarium should be set up and maintained. Considerable emphasis is placed in this book on the description of fish species that are suited to maintenance in a brackish-water aquarium. Not only are the classic brackish-water fishes mentioned above covered in detail, but many other beautiful, interesting, or bizarre species are presented as well. In addition, mention is also made of those fish species that, because of misidentification or incorrect information, are often classed as brackish-water fishes when they are in fact no such thing.
