Baby Catchers is an innovative tank design that dramatically improves fry recovery in livebearing fishes. By using controlled water flow to separate newborn fry from adults, it reduces cannibalism and stress while increasing survival rates. Ideal for aquarists and researchers working with poeciliids, goodeids, and halfbeaks in breeding programs worldwide.
This paper suggests a large update and breakup of the large Characidae family.
Old names, a new classification. The end of Corydoras as we know it. Probably the biggest news in the world of Corydoradinae catfishes in 40 years!
Pariolius maldonadoi and Pariolius pax, two new species of heptapterid catfishes are described from the Upper Orinoco and Upper Negro rivers in Colombia. Paywall – https://mapress.com/zt/article/view/zootaxa.5433.3.6 “Despite several ichthyological expeditions being carried out along the main rivers of the Colombian River and well-recorded Heptapteridae species in literature; Pariolius pax was found only in small creeks […]
Pimelodella guato, a new species is described from rio Paraguai basin in Mato Grosso do Sul and Mato Grosso States, Brazil. This new species can be diagnosed from all congeners by several exclusive characteristics, not least the long maxillary barbels reaching at least the anal-fin terminus.
Chiloglanis carnatus, a new species of riffle-dwelling catfish from the middle Zambezi River system, Zimbabwe is described. Results from this study add to the growing evidence of a high level of undocumented diversity within riffle-dwelling taxa in southern Africa. Open-access – https://zookeys.pensoft.net/article/114679/ The authors discuss the significance and implications of incomplete documentation of the diversity […]
Monotocheirodon duda, a new characid species with remarkable sexual dimorphism is described from the upper Guayabero River, Orinoco basin, Colombia. Researchers putatively place this new species in 𝑀𝑜𝑛𝑜𝑡𝑜𝑐ℎ𝑒𝑖𝑟𝑜𝑑𝑜𝑛 and discuss in depth the unique sexual dimorphic structures potentially linked to inseminating behaviour.
Fascinating research shows (in laboratory conditions) that electric eels (Electrophorus spp.) can temporarily modify nearby fish larvae DNA with their electrical impulses.
Serrasalmus magallanesi, a new species of piranha from the upper Madeira River basin in Bolivia is described. The authors note this new species has often been confused with Serrasalmus hollandi in literature previously. A key to Serrasalmus spp. from Bolivia is provided.
In this study researchers present a taxonomic revision of Phoxinus minnows (Leuciscidae) from the Caucasus and describe a new narrow-ranged endemic species Phoxinus adagumicus from the Adagum River basin, Russia.
