Table of contents


Xingu Corydoras (Corydoras xinguensis) has garnered a well-deserved reputation as a highly sought-after treasure within the captivating realm of the aquarium hobby. Renowned for their playful and quirky behaviour, these fish never fail to enchant their keepers with their delightful antics. While Xingu Corydoras may not be as widely available as some of their Corydoras counterparts, their uniqueness makes them a prized discovery for dedicated enthusiasts.

As social creatures, Xingu Corydoras thrive in the company of their own kind, necessitating a group of at least six individuals to create a harmonious shoal. Adaptable to a community aquarium, these peaceful fish can coexist amicably with a diverse array of gentle species. Consider delightful companions such as small Cyprinids, Characins, Dwarf Cichlids, Anabantoids, and other congenial Catfish. However, due to their lively nature, caution should be exercised when pairing them with smaller, more delicate fish, as the exuberance of Xingu Corydoras may inadvertently cause stress. In addition, it is imperative to avoid housing them with aggressive or predatory species to ensure a serene and harmonious aquatic environment.

True to their nature, Xingu Corydoras gracefully navigate the lower regions of the aquarium, diligently scouring the substrate in search of sustenance. To recreate their natural habitat, it is crucial to establish a well-designed aquarium that provides a gentle current flowing from end to end. This can be achieved by implementing efficient aeration and filtration systems, mimicking the dynamic water flow that Xingu Corydoras thrive in. In addition, introducing ample vegetation within the tank will serve multiple purposes, including breaking up lines of sight, offering sheltered hideaways, and providing shaded retreats for these captivating creatures.

Adorned with a flat-bellied body and a gracefully arched back preceding the dorsal fin, Xingu Corydoras exhibit a mesmerizing silvery-grey colouration. Their endearing snub snouts are adorned with lengthy barbels, adding an extra touch of charm. Embellishing their bodies are numerous small, ebony spots that elegantly speckle their form, commencing at the snout and continuing to the caudal peduncle. While their fins predominantly exude a translucent beauty, the caudal fin steals the spotlight with its striking arrangement of seven grey vertical columns of colour coursing through the rays, from root to tip.

With their captivating allure and enchanting behaviour, Xingu Corydoras are undeniably a prized addition to any aquatic haven, elevating the aquatic experience to new heights of splendour.

How to breed the Xingu Corydoras

In the realm of aquatics, the enigmatic process of spawning Xingu Corydoras unfolds within the confines of a well-planted aquarium, occasionally gracing the community tank with the emergence of resilient fry. Breeding among Corydoras is a unique spectacle, distinct from other fish species. A notable characteristic is the female's fascinating behaviour of attaching her mouth to the male's genital organ, ingesting the sperm. Then, swiftly traversing her digestive system, the sperm embarks on a transformative journey, joining forces with the eggs within a specialized pouch formed by her pelvic fins. Following this remarkable union, the female selects a suitable location to lay her eggs, marking the culmination of this intricate reproductive ritual.

To embark on a breeding venture with Corydoras, it is prudent to establish a separate breeding tank purposefully designed to accommodate their specific needs. While the tank itself may possess a minimalist aesthetic, it is advisable to furnish it with a soft substrate, offering a conducive environment for the Corydoras to forage in search of sustenance and providing a receptive bed for the female to deposit her eggs. In addition, adequate aeration is essential, as Corydoras thrive in an environment where water is gently agitated, eschewing stagnant conditions. As the breeding event draws near, astute observers will notice the female meticulously cleaning the surface of leaves or the aquarium glass, a telltale sign of her imminent readiness to spawn. In a mesmerizing display, the female will typically cradle and safeguard 2 to 4 fertilized eggs between her pelvic fins, subsequently depositing them in her chosen meticulously prepared locations. This process of egg deposition continues until the female's reserve is depleted, with prolific females capable of laying up to 100 eggs during a single spawning.

Following the completion of this awe-inspiring reproductive performance, it is crucial to remove the adult Corydoras from the breeding tank. Regrettably, they play no role in the upbringing of their offspring and may inadvertently consume the precious eggs if given the opportunity. Thus, a deliberate intervention is necessary to safeguard the eggs' chances of survival. Subsequently, a remarkable metamorphosis unfolds within the safe confines of the breeding tank. Within a span of 1 to 3 days, contingent upon optimal water conditions and temperature, the eggs will hatch, ushering forth a new generation of life. Then, two to three days later, as the yolk sacs are depleted, the fry will venture into the realm of free-swimming, heralding the dawn of their independent existence.

This captivating journey of reproduction underscores the remarkable resilience and intricate life cycle of Xingu Corydoras, reaffirming their significance within the realm of aquatic wonders.

Diet & feeding

Xingu Corydoras are highly adaptable when it comes to feeding, displaying opportunistic behaviour and readily consuming most sinking foods in the aquarium. Therefore, providing a balanced diet that includes dried food options like algae wafers, Catfish pellets, and granules is recommended. However, it is essential to supplement their diet with frozen or live foods such as bloodworm and brine shrimp to cater to their carnivorous nature. It is worth noting that these Corydoras also have a tendency to scavenge for injured, dying, or deceased fish at the bottom of the aquarium. While vegetable-based foods offer limited nutrition for their dietary requirements, a well-rounded feeding regimen will ensure their optimal health and vitality.

Feeding these Corys during the evening hours when the lights are dimmed is recommended, allowing them to embrace their preferred feeding time fully. However, these versatile fish can readily adapt to daytime feeding is encouraged.

As deliberate eaters, Xingu Corydoras appreciate a leisurely dining experience. To ensure their satisfaction, it is advised to offer them ample time, at least half an hour, to relish their meals. This patient approach ensures that these exquisite Corys have the opportunity to savour and consume their food at a comfortable pace.
