The Balzanii Argentine Humphead, native to the Paraná River basin area spanning Brazil, Paraguay, and Argentina, as well as the lower Uruguay drainage, thrives in groups along the banks of larger tributaries and flooded forest areas. Constantly sifting through sandy substrates, they feed on organic matter and small crustaceans.

Belonging to the Geophaginae subfamily of neotropical Cichlids, Gymnogeophagus eartheaters, like the Balzanii Humphead, exhibit specialized feeding behaviors, making them adept sand sifters. They are well-suited to temperate aquariums with temperatures ranging from the low to high 20°C.

With their peaceful to moderately aggressive temperament, Balzanii Humpheads make suitable tank mates for hardy community fish or compatible Cichlids. In community setups, they provide contrast to smaller schooling species, while in Cichlid tanks, they act as dither fish, deterring aggression and aiding in substrate cleaning.

Although less aggressive than other Geophagus species, they may not thrive with larger, more aggressive Geophagus in average-sized tanks. However, in larger setups with proper stocking and aquascaping adjustments, cohabitation may be possible.

In their natural habitat, they primarily feed by sifting through sandy bottoms, but they readily accept flake, pellet, and frozen foods in aquariums. A varied diet enhances their health, with a preference for sinking foods to mimic their natural feeding behavior.

Balzanii Humpheads form monogamous pairs and exhibit delayed mouth brooding, a strategy that enhances fry survival. After spawning, the female picks up the eggs in her mouth, providing parental care while the male guards the territory. Separating a mated pair into their own aquarium facilitates successful breeding.
