The Geophagus heckelii, also known as the Threadfin Acara or Heckelii Threadfin, is a South American cichlid from the northern Amazon Basin according to Aquatics Unlimited. They are characterized by their golden-brown to beige body with darker vertical bars, and unique thread-like extensions on their dorsal and anal fins. They are known for their “eartheater” behavior, sifting through the substrate for food.
