Description
Gymnogeophagus balzanii – The Argentine Eartheater
(Gymnogeophagus balzanii)
The Gymnogeophagus balzanii, also known as the Argentine Eartheater or Balzani’s Eartheater, is a peaceful and elegant South American cichlid found throughout slow-moving rivers and lagoons in Argentina, Paraguay, and Uruguay. This species is known for its fascinating sand-sifting behaviour and the striking appearance of mature males, which develop a pronounced nuchal hump during the breeding season.
Unlike most Geophagus species, G. balzanii thrives in cooler water, making it a great choice for unheated or temperate aquariums. They display attractive golden and turquoise hues with subtle iridescence that becomes more vivid in mature specimens.
