Cichlid | Eartheater Red Head Tapajos (Geophagus sp.)

The Eartheater Red Head Tapajos, scientifically classified as Geophagus sp., is a beautiful South American cichlid admired for its vivid red to orange head coloration and graceful sand-sifting behavior. Native to the Tapajós River basin in Brazil, this species constantly sifts sand through its mouth in search of food—hence the name eartheater.
