The Sterbai Corydoras (Corydoras sterbai) is one of the most admired and widely kept species in the corydoras family, valued for its striking appearance and ability to tolerate warmer water temperatures than most of its relatives. It has a dark brownish-black body covered with a dense pattern of small white or cream spots, transitioning to a bold white-spotted head with a pale face. The pectoral fin spines are bright orange, providing a vivid color accent against the darker body. Originating from the rivers and streams of the Guaporé river drainage in Brazil and Bolivia, the Sterbai Corydoras inhabits slow-moving, shallow water over sandy or silty substrate with abundant leaf litter and dense vegetation. Water temperatures in its native range can be warmer than many other corydoras habitats, and the Sterbai's tolerance of temperatures up to 30°C makes it one of the few corydoras species compatible with discus aquariums, where very warm conditions are standard. Like all corydoras, the Sterbai is a highly social, bottom-dwelling schooling fish that sifts through the substrate with sensitive barbels in search of food particles. It periodically darts to the surface to take atmospheric air, which is a normal and essential behavior. In groups of six or more, Sterbai Corydoras exhibit fascinating social interactions, synchronized movements, and are constantly active on the aquarium floor.
