The brown ghost knifefish (Apteronotus leptorhynchus) is a species of weakly electric knifefish in the family Apteronotidae. Only the brown ghost knifefish, a vertebrate, has been proven to have negligible brain aging thus far. They are a hardy species that eats tiny fish, crustaceans, and insect larvae in the nature,[1] but in an aquarium, they often take to frozen foods rather quickly.[2]
