Sands Corydoras - Corydoras davidsandsi : Complete Fish Profile & Care Guide
Table of contents
The Sands' Corydoras (Corydoras davidsandsi) is a striking Catfish species that thrives in well-established softwater aquariums. These exquisite Corys are renowned for their ease of care and impressive hardiness, although they may exhibit a somewhat shy nature. Nonetheless, they make a superb addition to any community aquarium, showcasing captivating behaviours that captivate onlookers.
To ensure optimal well-being, it is advisable to maintain this peaceful bottom-dwelling species in groups of at least five or more individuals, as they exhibit a shoaling nature. By accommodating them in more significant numbers, you provide an environment in which these fish feel more secure, leading to a more natural and visually captivating display. Ideally, Sand's Corydoras can be harmoniously housed alongside other peaceful species, including smaller Pencilfish, Tetras, Dwarf Barbs, and Rasboras. The presence of midwater-dwelling companions will encourage the Sand's Corydoras to venture out into view more frequently, enhancing the overall aquarium experience.
A fine sand substrate is the preferred choice for these Corydoras, although smooth gravel can serve as an acceptable alternative, provided it is kept relatively clean. Regarding decor, personal preference plays a significant role; however, it is crucial to prioritize providing ample shelter and security for your fish. Utilizing driftwood, rocks, and hardy aquatic plants can effectively achieve this goal. It is vital to ensure that the decor does not feature any sharp edges that could potentially harm or injure the fish.
Maintaining high water quality is of paramount importance for the Sand's Corydoras, as their health can rapidly decline in suboptimal conditions. Regular maintenance practices, including frequent partial water changes, are essential to ensure the well-being of these fish. By diligently upholding these measures, you can keep the Sand's Corydoras in a favourable and healthy state.
The Sand's Corydoras boasts a light brown body accentuated by a distinct black band extending across its head and eyes. Additionally, they exhibit a bold second black stripe that diagonally descends from the top of their dorsal fin to the base of the caudal fin lobe, branching at its root. Notably, the gill cover displays a faint orange spot, while the flanks do not possess further distinguishing markings.

Distinguishing between male and female Sand's Corydoras can be accomplished with relative ease. By observing their physical characteristics, notable distinctions can be identified. When viewed from above, females exhibit a slightly greater length and possess a higher body profile compared to males. Their wider appearance is particularly noticeable in the underbelly region. Conversely, males display a shorter and slimmer physique in comparison to their female counterparts. These discernible differences provide valuable insights for distinguishing between male and female Sand's Corydoras.

The Sand's Corydoras exclusively inhabits the Rio Unini, a significant tributary within the vast Negro River Basin located in Brazil, South America. These remarkable Corys thrive in the dynamic and rapid-flowing waters that characteristically bear a rich tannin-stained hue. The aquatic environments they call home encompass a diverse range of habitats, including rivers, streams, and lakes.
The natural habitats of the Sand's Corydoras are distinguished by their notably acidic water conditions. The presence of tannins imparts a slight acidity to the waters in which they reside. Within these aquatic realms, the substrate predominantly consists of a complex arrangement of twigs, branches, and decomposing leaves, forming a natural carpet beneath the Corys' delicate fins. This unique composition contributes to the distinct visual aesthetic and ecological dynamics of their habitat.
Surrounded by lush and verdant rainforests, the Sand's Corydoras finds solace and sustenance in the embrace of these dense and thriving ecosystems. The intertwining canopies overhead filter the sunlight, creating a subdued and enchanting atmosphere that is integral to the species' existence.
Breeding the Sand's Corydoras can be achieved with relative ease when appropriate water parameters are maintained. To initiate the breeding process, it is advisable to place two males with each female into a separate breeding tank containing established, well-oxygenated water, providing ample plants or designated areas for the female to deposit her eggs.
When the females display noticeable signs of being gravid with eggs, stimulating spawning can be accomplished by simulating a rainstorm-like environment. This can be achieved by executing a significant water change, replacing it with cooler water, and enhancing oxygenation and water flow within the tank. This process should be repeated daily until the fish successfully spawn.
Once ready to spawn, the pair will engage in the characteristic 'T position.' During this reproductive act, the males fertilize the eggs positioned between the female's pelvic fins, after which the female carefully deposits the eggs onto the sides of the aquarium, plants, or available decor.
Upon spawning completion, removing the adult fish or the eggs from the breeding tank is recommended. If the decision is made to transfer the eggs, the raising tank must replicate the water parameters of the spawning tank and possess efficient oxygenation. Some breeders incorporate Alder Cones into the raising tank, while others introduce a few drops of methylene blue. These measures help prevent fungal growth on the eggs, safeguarding their development.
The incubation period typically spans between 3 and 5 days, after which the hatched fry can be provided with powdered fry food for initial sustenance, gradually transitioning to small live food sources such as microworms and baby brine shrimp as they continue to grow.
Diet & feeding
The Sand's Corydoras demonstrates a relatively adaptable feeding behaviour within the confines of a home aquarium. These fish readily accept high-quality sinking dried foods and a variety of small live, frozen, and freeze-dried food options, including bloodworms, Tubifex worms, and mosquito larvae. It is crucial to emphasize the significance of providing a diversified diet to ensure the overall well-being of your Corys.
It is important to note that the Sand's Corydoras should not be solely reliant on leftover food from other aquarium inhabitants or expected to fulfil a "cleaning" role within the aquarium. Their nutritional needs should be intentionally addressed through regular and deliberate feeding practices. By offering a balanced and varied diet, you contribute to the overall health and satisfaction of your Sand's Corydoras.
