This is the first aquarium hobby monograph on fresh- and brackish-water pufferfishes. The author, who has been keeping these fishes for more than 40 years, provides detailed maintenance data on 29 species from this fascinating group. All described fresh- and brackish-water species, from all over the world, are portrayed in the identification section of this AQUALOG. Some 300 stunning color photographs offer proof that puffers are not only useful snail-eaters but also colorful fishes, extraordinary in their form.
