Desana Corydoras - Corydoras desana : Complete Fish Profile & Care Guide

Table of contents


The Desana Corydoras (Corydoras desana) epitomizes peaceful and sociable qualities, making it a valuable addition to both community aquariums and species-specific setups. However, due to its sensitivity to water conditions, this species is better suited for aquarists with some experience rather than beginners. In its natural habitat, the Desana Corys exhibit shoaling behaviour, necessitating the maintenance of a group comprising at least six individuals to ensure their well-being. Isolated specimens may become reclusive, easily stressed, and more prone to illness.

Suitable tankmates for the Desana Corydoras include fellow bottom-dwelling species such as Otocinclus, Tetras, Pencilfish, Dwarf Cichlids like Apistogrammas, Rasboras, smaller Barbs, as well as compatible shrimp and aquarium snails. However, caution must be exercised when selecting tankmates, as aggressive fish may pose a risk to the Desana Corys due to their possession of venomous spines. Utilizing fine sand as the substrate in the aquarium is highly recommended, although smooth gravel can also be used, provided it is regularly cleaned. While ornate aquarium decor is not essential, providing adequate hiding places using bogwood, rocks, tall aquatic plants, or floating foliage enhances the sense of security for these fish. The inclusion of dried leaf litter further enriches their environment.

The Desana Corydoras boasts an iridescent cream body adorned with three distinct dark blotches along its frame. The first blotch is located on the head at eye level, followed by the humeral blotch positioned at the dorsal fin level, and the final blotch is present on the caudal peduncle. Notably, the opercular region exhibits partial translucency, imbued with a reddish hue that stems from the underlying gills. These Corys display six slender vertical stripes originating from the caudal fin base and extending to the tip of the caudal fin lobes. Additionally, a discreet vertical dark line graces the centre of their anal fin, while the remaining fins remain transparent. The Desana Corys possess captivating black eyes accentuated by an inner yellow ring and a distinctive saddle nose, adding to their overall appeal.

Sexual Dimorphism

Differentiating between male and female Desana Corydoras presents a notable challenge; however, specific observations can aid in discerning their gender. Females tend to exhibit a slightly larger size and possess a fuller body shape, a distinction that becomes more apparent when viewed from above. In contrast, males generally appear somewhat smaller and exhibit fins with a more pointed morphology. Careful examination of these characteristics can provide valuable insights into distinguishing between male and female Desana Corydoras.

Natural Habitat

Desana Corydoras are exclusively found in the captivating Igarapé Castanha, a tributary of the Rio Tiquié within Brazil's upper Rio Negro Basin. These remarkable fish find solace amidst the crystal waters enriched with sediments, creating a distinct aquatic environment. Their preferred habitats include rivers, streams, and oxbow lakes, surrounded by the lush greenery of the rainforest. The sandy substrate provides a natural backdrop for their graceful presence in these pristine South American waters.

Breeding Desana Corydoras poses a challenge due to the limited information available, as this species has recently been described. However, it is likely that their breeding behaviour follows patterns observed in other Corydoras species. Therefore, establishing a separate breeding tank is advisable, accommodating two or more males per female. Once the females display signs of being full of eggs, a significant water change of 50 to 70 per cent should be conducted using cooler water, simultaneously increasing oxygenation and flow within the tank. This process should be repeated daily until spawning occurs.

The Desana Corydoras will deposit their eggs on the tank glass, amidst fine-leaved plants, or within submerged spawning mops. Following the completion of the spawning process, it is necessary to remove either the adult fish or the eggs from the breeding tank. If the decision is made to move the eggs, the raising tank must possess identical water parameters to the spawning tank while also ensuring proper oxygenation. Some breeders incorporate a few drops of methylene blue or alder cones into the raising tank to prevent fungus development on the eggs. The incubation period typically lasts 3 to 4 days, after which the fry will consume their yolk sacs. At this stage, providing small live foods such as microworms and baby brine shrimp becomes essential for their nourishment.

Raising Desana Corydoras fry presents a significant challenge, as they demand excellent water quality for their well-being. Maintaining a thin layer of sand within the tank, as opposed to a bare tank, mitigates disease susceptibility, contributing to their successful rearing. Diligent attention to water quality and appropriate feeding protocols are vital aspects of ensuring the healthy development of Desana Corydoras fry.

Diet & feeding

Desana Corydoras exemplify foraging omnivores, drawing sustenance from a diverse array of food sources in their natural habitat. Their diet predominantly comprises small worms, crustaceans, insects, detritus, and plant matter. However, in the controlled environment of an aquarium, these fish exhibit remarkable adaptability and readily accept various food offerings.

To ensure the optimal health of your Corys, it is recommended to provide a well-rounded diet encompassing flakes, granules, sinking dry foods, and frozen or live options like Tubifex, bloodworms, and brine shrimp. Offering this mixture of nourishment caters to their natural dietary preferences and promotes their overall well-being. It is important to note that relying on leftover food from other aquarium inhabitants or assigning them the task of cleaning the aquarium is unsuitable for sustaining Desana Corydoras. Instead, a purposeful and diversified diet is key to their proper nutrition and vitality.
