Sterba's Corydoras, Corydoras sterbai, is a highly sought-after species in the aquarium hobby, cherished for its striking appearance and amiable nature. Originating from the freshwater habitats of South America, specifically in the upper Rio Guaporé region between Bolivia and Brazil, this species belongs to the Corydoradinae subfamily, which is celebrated for its diverse and attractive members.

Corydoras sterbai distinguishes itself with a unique color pattern: a dark body speckled with white to gold spots and a lighter, often pinkish underbelly. What sets it apart from many other Corydoras species is the inversion of the common color scheme found in Corydoras; Sterba's Corydoras has light spots on a dark background, whereas many others have dark spots on a lighter background. Another distinctive feature is its dark face with light spots, along with a clear patch on the dorsal fin that is surrounded by dark coloration.

Adults typically reach a manageable size, making them suitable for a variety of aquarium setups. They are renowned for their bottom-dwelling behavior, spending much of their time foraging for food in the substrate. This behavior underscores the importance of a soft, sandy substrate in the aquarium to prevent damage to their sensitive barbels.

Sterba's Corydoras are social creatures that thrive in groups, displaying more natural behaviors and appearing more confident when kept with conspecifics or other peaceful fish. A group of six or more is recommended to create a comfortable social environment for these fish.

In terms of care, Corydoras sterbai is relatively easy to maintain, making it suitable for both novice and experienced aquarists. They prefer clean, well-oxygenated water with a mild current and appreciate a well-planted tank with plenty of hiding places. Their diet is omnivorous, consisting of high-quality sinking pellets, flakes, and occasional live or frozen foods such as bloodworms, daphnia, and brine shrimp, which provide the necessary nutrients for optimal health.

Breeding Sterba's Corydoras in captivity is achievable and can be a rewarding experience. They are egg layers, with females laying adhesive eggs on the aquarium glass, plants, or decor after a fascinating courtship display by the males. To encourage spawning, aquarists may simulate rain season conditions by performing large water changes with slightly cooler water and increasing feeding with high-quality live foods.

Despite their resilience, it's crucial to maintain good water quality and a stress-free environment for Corydoras sterbai to prevent common health issues. Their peaceful nature and striking appearance make them a popular choice among aquarists looking to add a lively and attractive group of bottom-dwellers to their community aquarium.
