Brasiliensis Eartheater

Geophagus brasiliensis is one of the most widespread and adaptable eartheaters, found in coastal river systems of Brazil and Uruguay. Unlike most of its relatives it tolerates cooler temperatures and harder water, making it a practical choice for keepers who cannot maintain tropical conditions year-round. Males develop an impressive nuchal hump and display rich iridescent scaling with maturity.

Best kept as a pair or small group in a large aquarium with a deep fine-sand substrate. Despite its adaptability, it benefits greatly from clean, well-filtered water and regular partial water changes. Provide open swimming space with scattered rocks and driftwood for territory definition.

In the wild it feeds by sifting substrate for invertebrates, detritus, and plant matter. In captivity it readily accepts quality sinking cichlid pellets, frozen bloodworm, brine shrimp, and occasional vegetable matter. A rewarding and long-lived species for the dedicated South American cichlid keeper.

Water: 20-28°C, pH 6.0-7.8, soft to moderately hard (2-15 dGH) — one of the hardiest Geophagus. Tank: Minimum 300L, deep fine sand at least 8 cm, scattered rocks and driftwood to define territories. Feeding: Quality sinking cichlid pellets, frozen bloodworm, brine shrimp, chopped earthworm, occasional spirulina wafer. Breeding: Biparental mouthbrooder; pairs spawn on flat surfaces and both parents carry fry; condition on live foods. Compatibility: Semi-aggressive; best with similar-sized robust South American species; avoid very small tankmates.
