Geophagus steindachneri, known as the Redhump Eartheater, is a freshwater fish native to Colombia and Venezuela. It inhabits slow-moving rivers and lakes, showing a preference for sandy substrates. This cichlid is recognized for its unique feeding behavior, sifting through substrate to find food, and their striking red hump on males.

Geophagus steindachneri, commonly known as the Redhump Eartheater, is native to northern South America. This species is primarily found in Colombia and Venezuela, particularly within the Orinoco River basin and its tributaries.

Geophagus steindachneri inhabits slow-moving rivers, streams, and floodplain areas with sandy or muddy substrates. The environmental conditions of these habitats typically include tropical climates with warm temperatures ranging from 24°C to 28°C (75°F to 82°F). The water in these areas is often slightly acidic to neutral, with pH values between 6.0 and 7.5.

In its ecological niche, Geophagus steindachneri plays a role as a benthic feeder, sifting through the substrate to consume detritus, small invertebrates, and plant matter. This species is well-adapted to environments with fluctuating water levels and may exhibit territorial behaviors during breeding seasons.
