The Table of Contents for the July/August 2023 issue of AMAZONAS Magazine. You can view this TOC online!AMAZONAS Executive Editor Courtney Tobler introduces the issue, proposing no matter what this summer brings, there’s a fishy respite whether reading AMAZONAS poolside or donning a mask and snorkel to dive into whatever water is nearby!The AMAZONAS Aquatic Notebook presents short stories of relevance to the freshwater aquarist from around the globe. We kick off this latest installment with a report from Dr. Paul V. Loiselle explaining the new scientific name for an aquarium classic, the Buenos Aires Tetra.Courtney Tobler shares exciting news for noteworthy Corydoras enthusiast Rob McLure; meet the new Corydoras maclurei.Also in this issue’s Aquatic Notebook, learn about the special iridescence that is unique to Glass Catfish.Ernst-Otto von Drachenfels shares that French Guiana is home to at least two species of Guianacara cichlids. As adults, these small cichlids are real eye-catchers in nature and the aquarium.Killifishes are crowd-pleasers with their vibrant hues and largely placid dispositions. Laimosemion xiphidius, the Blue Striped Rivulus, is a particular favorite of author Friedrich Bitter, and might even be capable of inducing love at first sight.Ernst-Otto von Drachenfels reveals that different populations of the same species can exhibit variability in their color patterns. Such variable color patterning is an intriguing feature of the Amapa Corydoras (Corydoras amapaensis) from northern South America.When keeping tetras that are uncommon in the hobby, like Astyanax leopoldi (Leopold’s Tetra), you may find little information available about breeding them. After a bit of perseverance, author Ernst-Otto von Drachenfels has found success rearing this yellow gem from French Guiana.Many aquarists have probably never paid much attention to the thorny catfishes, but some species are very well suited to aquarium maintenance. Anja Katzschmann and Norman Behr offer a thorough examination of Doradidae, the thorny catfish family.Pike-like in appearance but peaceful in demeanor, the African Epiplatys killifishes are good options for those looking to keep killies. Author Gregory J. Niedzielski makes an introduction.Fishes sometimes inhabit very extreme, unusual habitats, and it is often surprising to learn about such biotopes and the species that exploit them. Rice fields are certainly one of the more unique habitats. A variety of fishes swim in these artificial waterways, at least temporarily. Author Anton Lamboj details two trips that allowed for collecting fishes in the rice fields of southern Vietnam.Equipped with a diving mask, a snorkel, and a waterproof camera, author Roman Burkardt documents the occupants of two streams in the southeastern U.S.Ute Dederer details the husbandry and breeding of a particularly interesting and sexually dichromatic loach, the Rosy Loach, Petruichthys sp. ‘Rosy’.Uwe Werner shares the husbandry and breeding of Geophagus parnaibae, a modestly-sized South American eartheater cichlid species that was discovered in the Río Parnaíba in northeast Brazil.Whether grown as lush green carpets or single statement pieces, Rudolf Suttner illustrates how the plant genus Eleocharis offers a range of hairgrass species and varieties that aquarists can use in their planted aquarium.Multi-day and national events are great opportunities to come together with fellow aquarists to learn new things, make new friends, and even obtain some of the hobby’s rarest fishes.
