Remarks: Nego Dagua Tetras are small tetras from Brazil. They have silver/gray bodies with white tips on their dorsal and anal fins. They do well in community set-ups and planted tanks with both bright or subdued lighting. The Nego Dagua is fairly rare and a new tetra to the hobby.
The scientific name for the nego dagua tetra used to be Hyphessobryconnegodagua. However, it was reclassified as Hasemania negodagua after the completion of an intensive phylogenic study on species in the family Characidae. Many other species were reclassified as well as a result of this study which can be read here: https://academic.oup.com/zoolinnean/article-abstract/202/1/zlae101/7748269
The following article also provides a good breakdown of the results of the study and does not have a paywall: https://aquainfo.org/the-end-of-the-characidae-family-as-we-know-it/
