The royal tetra (Inpaichthys kerri) is a species of freshwater ray-finned fish belonging to the family Acestrorhamphidae, the American characins. This fish is endemic to Brazil, where it is found in tributaries of the Aripuanã River. It was once the sole member of its genus.
The fish was named in honor of Warwick Estevam Kerr (1922–2018), a Brazilian agricultural engineer, geneticist, entomologist, and director of Instituto Nacional de Pesquisas da Amazônia, whose field station in Núcleo Aripuanã, Mato Grosso, Brazil, is near the area where the specimen was discovered.
