The Xingu corydoras (Corydoras xinguensis) is a captivating freshwater catfish native to Brazil's upper Xingu River basin. Renowned for its peaceful demeanor and distinctive appearance, this species has become a favorite among aquarists. Its manageable size and engaging behaviors make it an excellent choice for both novice and experienced fishkeepers.
What makes the Xingu corydoras appealing to aquarists?
Its tranquil nature, unique coloration, and active bottom-dwelling habits add both visual interest and dynamic movement to community aquariums.
Is the Xingu corydoras suitable for beginners?
Yes, with proper care and attention to water parameters, it is well-suited for beginners seeking a hardy and sociable fish.
Providing optimal care for the Xingu corydoras involves replicating its natural habitat conditions. A minimum tank size of 60 liters is recommended, with a larger volume of 100 liters or more ideal for groups of six or more individuals. Maintaining water temperatures between 22°C and 26°C, a pH range of 6.0 to 8.0, and water hardness between 2 to 25 dGH is essential. Efficient filtration and moderate lighting are crucial to ensure water quality and mimic the subdued lighting of their native environment.
What type of substrate is best for Xingu corydoras?
A soft, sandy substrate is ideal to protect their delicate barbels and encourage natural foraging behaviors.
How should the tank be decorated?
Incorporate live plants, driftwood, and hiding spots to provide shelter and replicate their natural surroundings.
As omnivores, Xingu corydoras thrive on a varied diet that includes high-quality sinking pellets, live or frozen foods like bloodworms and brine shrimp, and occasional vegetable matter. Feeding them in the evening aligns with their natural nocturnal tendencies, but they can adapt to daytime feeding schedules.
Are Xingu corydoras sensitive to water changes?
Yes, they can be sensitive to sudden changes. Regular, small water changes are recommended to maintain stability.
Can they be kept with other bottom dwellers?
Yes, but ensure tank mates are peaceful and not overly competitive for space or food.
Native to South America's upper Xingu River basin in Brazil, the Xingu corydoras inhabits slow-flowing streams, river margins, lakes, marshlands, and ponds. These environments are characterized by soft substrates, abundant vegetation, and gentle currents, providing ample hiding spots and foraging opportunities.
What type of water conditions do they prefer in the wild?
They thrive in tropical climates with temperatures ranging from 22°C to 26°C and a pH between 6.0 and 8.0.
Do they experience seasonal changes in their habitat?
Yes, seasonal variations can affect water levels and flow, influencing their breeding and feeding behaviors.
The Xingu corydoras is a peaceful, social species that thrives in groups of at least six. They are compatible with other non-aggressive fish such as small tetras, rasboras, and dwarf cichlids. Their active bottom-dwelling nature adds liveliness to the aquarium without disturbing other inhabitants.
Can they be kept with larger fish?
It's best to avoid housing them with large or aggressive species to prevent stress or predation.
Do they require a specific group size?
Yes, keeping them in groups of six or more promotes natural behaviors and reduces stress.
The Xingu corydoras possesses the unique ability to "blink" by tilting its eyes downward, a behavior that fascinates many aquarists. Additionally, they are facultative air breathers, occasionally gulping air at the water's surface to supplement oxygen intake. This adaptation allows them to survive in low-oxygen environments.
Why do they gulp air at the surface?
This behavior helps them extract oxygen from the air, especially in environments with low dissolved oxygen levels.
Are they known by any other names?
In the aquarium trade, they have been assigned C-numbers such as C55, C105, C106, C107, and C108 to identify different variants.
