The Spanish toothcarp (Aphanius iberus), also known as Fartet, Spanish pupfish or Iberian killifish, is a small, endemic species of fish in the family Cyprinodontidae. Its risk of extinction is one of the greatest of any Iberian vertebrate. Its limited range, coupled with the drastic population decline the species has suffered in the last two decades due the presence of the invasive Gambusia affinis, has caused it to be placed on endangered species lists, both in Spain and internationally. In addition, habitat fragmentation, likely due to humans, has resulted in this species becoming increasingly stagnant and has led to increased genetic drift. In nature it is a valuable part of food chains and ecosystems.
