Reticulated Corydoras - Corydoras reticulatas : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Reticulated Corydoras (Corydoras reticulatus) is a highly suitable choice of catfish for a well-established community aquarium. These visually striking and unique fish are relatively easy to care for, making them ideal for both beginner and experienced aquarists. Renowned for their hardiness and undemanding nature, the Reticulated Corydoras add beauty and charm to any aquarium setting.
To ensure the well-being and natural behaviour of the Reticulated Corydoras, it is recommended to keep them in groups of at least six individuals. This shoaling species thrives in larger numbers, resulting in a more dynamic and visually appealing display. When selecting tankmates, compatibility with other peaceful species such as Dwarf Cichlids, Tetras, small to medium-sized Barbs, Gouramis, and other peaceful catfish should be considered. While Reticulated Corydoras may occasionally prey on smaller dwarf shrimp, they coexist peacefully with larger shrimp and other ornamental invertebrates. It is advisable to avoid housing them with larger, more aggressive fish, as this may lead to intimidation and food competition.
The Reticulated Corydoras should be kept on a soft sand substrate to protect their delicate barbels. Providing ample bogwood and well-planted areas with shade enhances their sense of security and mimics their natural habitat. Due to their sensitivity to elevated nitrate levels, regular partial water changes are crucial to maintaining optimal water quality. It is worth noting that this species does not tolerate high temperatures well.
Visually, the Reticulated Corydoras exhibits a captivating silver body adorned with intricate dark swirl patterns. The distinct flag tail pattern further accentuates their unique beauty. Additionally, a large dark blotch often covers a significant portion of their dorsal fin, adding to their overall appeal.

Sexual Dimorphism
When properly conditioned, the sexual dimorphism in Reticulated Corydoras becomes quite apparent. The distinguishing characteristics between males and females are readily observable. Females exhibit a more prominent feature with a larger underbelly, resulting in a visibly wider appearance when viewed from the top. In contrast, males of this species tend to be slightly shorter in length compared to their female counterparts. By carefully observing these physical attributes, aquarists can discern the gender of their Reticulated Corydoras with relative ease.

Natural Habitat
The Reticulated Corydoras is indigenous to the Amazon River, specifically found in the region of Monte Alegre in Pará State, Brazil, South America. These esteemed fish primarily inhabit shallow aquatic environments characterized by moderate water currents and a sandy substrate. Notably, they exhibit fascinating social behaviour, often forming extensive aggregations within their natural habitat.
Breeding
To successfully breed Reticulated Corydoras, it is recommended to have a dedicated breeding tank with a ratio of two or more males per female. When the females exhibit a noticeable fullness indicating they are carrying eggs, it is advisable to initiate a significant water change ranging from 50 to 70 per cent, utilizing cooler water to stimulate spawning behaviour. Additionally, enhancing oxygenation and water flow in the tank is crucial during this period. It is advisable to repeat the water change procedure daily until the fish spawn.
During the spawning process, Reticulated Corydoras will deposit their eggs on various surfaces such as the tank glass, fine-leaved plants, or submerged spawning mops. Once the spawning is completed, it is recommended to remove either the adult fish or the eggs from the breeding tank. If the decision is made to move the eggs, it is essential to ensure that the raising tank maintains the same water parameters as the spawning tank, including similar levels of oxygenation. Some breeders opt to add a few drops of methylene blue or introduce alder cones into the raising tank to prevent fungal development on the eggs.
Typically, the incubation period for Reticulated Corydoras eggs lasts between 2 to 4 days. After hatching, the fry will rely on their yolk sacs as a source of nutrition. Once they have consumed their yolk sacs, it is recommended to provide them with small live foods such as microworms and baby brine shrimp. Successfully raising Corydoras fry can be challenging, primarily due to their requirement for excellent water quality. Keeping them over a thin layer of sand instead of a bare tank has been shown to reduce their susceptibility to diseases.
By following these breeding guidelines and providing optimal care, aquarists can increase their chances of successfully breeding Reticulated Corydoras and ensuring the healthy development of their fry.
Diet & Feeding
In the confines of a home aquarium, the Reticulated Corydoras readily accept a diverse array of high-quality dried food options. These meticulously formulated modern food products have been specifically designed to fulfil the nutritional requirements and promote the overall well-being of these fish. Granules, flakes, and sinking pellets constitute the primary dietary choices for these Corydoras, providing essential nourishment to sustain their health.
Supplementing the diet of Reticulated Corydoras with additional foodstuffs can offer notable advantages to their overall vitality, albeit not mandatory. The inclusion of live, frozen, or freeze-dried fare such as bloodworm, daphnia, and tubifex once or twice a week can offer supplemental benefits to their health and well-being. However, it is crucial to exercise caution when offering bloodworms, as they should be considered an occasional treat rather than a staple diet. Due to their challenging digestibility, excessive consumption may lead to potential blockages.
In their natural habitat, Reticulated Corydoras exhibit omnivorous tendencies, encompassing the consumption of both animal and vegetable matter. While most modern fish foods adeptly address this dietary requirement, augmenting their diet with blanched vegetables like spinach, broccoli, and zucchini can serve as a supplemental measure. Maintaining a balanced feeding regimen is paramount to avoid overfeeding, and any uneaten food should be promptly removed from the aquarium the following day to prevent water quality deterioration.
