Geophagus sveni (Rio Araguari) - South American Eartheater • Peaceful Cichlid • Natural Sand Sifter

Geophagus sveni (Rio Araguari) is a beautiful South American eartheater cichlid prized for its gentle temperament, elegant body shape, and fascinating sand-sifting behavior. Native to the Rio Araguari drainage in Brazil, this species constantly filters sand through its gills while foraging, creating a dynamic and natural aquarium display.

Known for being one of the more peaceful Geophagus species, G. sveni is an excellent choice for large community cichlid aquariums. As they mature, they develop subtle iridescent coloration with red, blue, and gold highlights, especially when kept in proper water conditions and fed a high-quality diet.

This species thrives in aquariums with fine sand substrate, driftwood, and open swimming space, making it ideal for natural South American biotope setups.
