Habitat
FishBase records the species from the western Amazon River basin. Seriously Fish places it in north-western Amazon tributaries in Ecuador and Peru, particularly the Río Napo system. It is a tropical freshwater, demersal fish; aquaria use fine sand, with rounded gravel acceptable if kept clean.
Tank requirements
- Minimum tank volume: 200 L (base around 120 × 45 cm)

Diet
The species is an omnivorous forager. Seriously Fish notes it accepts sinking pellets and live foods such as bloodworm and Tubifex, and requires varied nutrition rather than relying on tank detritus.
Compatibility
Seriously Fish describes the species as peaceful and social, best kept in groups of at least six to eight individuals. As a larger, robust cory it suits roomy community tanks with calm tank mates and should be kept away from aggressive cichlids.
Breeding
Seriously Fish reports that reproduction of this species is unrecorded in the available literature.
