The Gold Dust Eartheater (Geophagus sp. ‘Gold Dust’) is a striking American Cichlid native to the river systems of South America, particularly within the Amazon Basin. Known for their peaceful temperament and unique feeding behavior—sifting substrate through their gills in search of food—these cichlids are ideal for well-maintained community aquariums. Their golden-bronze shimmer, accented with red and blue hues, enhances the visual appeal of any South American biotope.
