David Alderton’s investigation of anabantoids—the bettas and gouramis, including Siamese fighting fish, paradisefish, and kissing gouramis—begins with a look at the origins of these adaptable and widely varying fishes in their Asiatic homelands, where they’ve been popular for hundreds of years. Given the considerable size range of this group of fishes, from the tiny licorice gourami (only 1.5 in or 4 cm in length) to the giant gourami (about 28 in or 70 cm), there are great differences to be considered by the fish keeper, all of which are addressed by Alderton in this color guide. The anabantoids is also a large group of fishes, with one hundred varieties/species available in most pet and hobby stores. The book provides photographs and images of dozens of the most popular examples.
