Rivulus is a GENUS of freshwater fish in the Aplocheilidae family of Cyprinodontiformes. It was formerly considered to be the largest genus in its family; however, the genus's size is currently in dispute. Wilson J. E. Costa split this genus into several new genera (including Anablepsoides, Atlantirivulus, Cynodonichthys, and Laimosemion) in 2011 leaving only a few species left in Rivulus itself.[1] A year later, J.H. Huber released a second paper refuting the proposed split, placing the above genera back in Rivulus and again making the genus the largest in the family Aplocheilidae.[2] Members of Rivulus and its disputed sister taxa are sometimes kept as aquarium fish.

Distribution

The species indisputably remaining in this genus are found in South America (R. formosensis and R. tomasi), Cuba and the Isle of Pines (R. berovidesi, R. cylindraceus and R. insulaepinorum), and Hispaniola (R. roloffi). If Anablepsoides, Atlantirivulus, Cynodonichthys, Laimosemion and Melanorivulus are reintegrated back into Rivulus, the genus has an enormous range from Central America to Northern Argentina.

Species

The following 7 species are considered part of Rivulus:[3]
