Gymnogeophagus labiatus

Gymnogeophagus labiatus is a rare and beautifully patterned eartheater cichlid known for its metallic sheen, subtle reds, and sand-sifting behavior. Native to cooler regions of South America, this species stands out for both its coloration and its unique habit of constantly filtering substrate through its gills.

Peaceful compared to many cichlids, it’s an excellent choice for hobbyists looking to build a natural, South American-style aquarium with movement and personality.
