Petitella georgiae Géry & Boutière, 1964

Petitella georgiae, the false rummy-nose tetra, is a species of characin found in Amazon Basin in Brazil and Peru. ^[2] It is a very popular aquarium fish. It resembles two species from its genus, Petitella bleheri and Petitella rhodostoma . It is distributed in the upper Amazon basin in Peru, Rio Purus, Rio Negro, and Rio Madeira basins (which has been found in an aquarium fish import from Peru in the late 1950s in Switzerland by H. Boutiere). ^[3] Some specimens have a black stripe in the caudal peduncle extending forwards into the body, surmounted above by a thin iridescent gold line; however, whether this feature is a reliable determinant of species identity has yet to be fully ascertained. ^[4]

Etymology

The fish is named in honor of Géry’s wife, Georgie, or Georgette. ^[5]
