Xingu Corydoras (Corydoras xinguensis)

Like all Corydoras species, Xingu Corydoras are extremely popular in the aquarium hobby. These fish are very peaceful and can perform strange antics in the water, much to the joy of their keepers. However, Xingu Corydoras are not quite as prevalent in the trade as other Corydoras species; and are worth looking out for.

Xingu Corydoras are shoaling fish, so they should be kept in a group of at least six individuals. These fish are suitable for a community aquarium as long as they are kept alongside other peaceful species. Ideal tankmates for this fish could include small Cyprinids, Characins, Dwarf Cichlids, Anabantoids, and other peaceful Catfish. However, these fish are very active and may stress out smaller fish. In addition, you should avoid housing these Corys with aggressive or predatory species.

Xingu Corydoras usually inhabits the bottom of the aquarium, where they typically feed in the lower areas of their environment, searching for food in the substrate. These Corydoras enjoy flowing water, not still or stagnant water; therefore, the aquarium needs to be set up to have a current of water from one end to the other. Routine aerations and filtration systems generally provide this. In addition, having plenty of vegetation to break up lines of sight will also help protect your Corydoras from predation, make them feel more secure, and provide hiding spaces and shaded areas.

Xingu Corydoras have a flat-bellied body and an arched back in front of the dorsal fin, and their bodies are silvery-grey. These fish have a snub snout and pretty long barbels. Other than their belly, the Xingu Corydoras are covered in small, black spots distributed evenly and separately over their body. These spots start at the snout and continue to the caudal peduncle. The fins are all essentially hyaline and relatively plain except for the caudal fin that has seven grey vertical columns of colour in the rays from root to tip.

Xingu Corydoras

Natural Habitat

Xingu Corydoras are endemic to the upper Xingu River Basin in Brazil in South America. These fish inhabit slow-flowing to almost still streams, margins of larger rivers and lakes but can also be found in marshlands and ponds.

Xingu Corydoras are most active at night; therefore, it is recommended that you feed them once the lights are out. However, you can easily persuade these fish to feed during the day. These Corys are slow eaters; therefore, you should give them at least half an hour to consume their food.

What to feed the Xingu Corydoras

Xingu Corydoras are opportunistic feeders and will eat most food that sinks to the bottom of the aquarium. You should offer these fish dried food such as algae wafers, Catfish pellets and granules. These Corydoras do have a carnivorous side, so make sure you supplement the dried food with frozen or live foods such as bloodworm and brine shrimp. These Corys will also eat any injured, dying or dead fish lying on the bottom of the aquarium. Vegetable-based foods present little nutrition to them.

How to Sex the Xingu Corydoras

The female is generally larger, more profound and has a broader body than the male. The females also display less intense colour than the male in the body at spawning times. In contrast, males tend to be somewhat slimmer, and their colouring is more intense in the body than females.

How to Breed the Xingu Corydoras

In a well-planted aquarium, Xingu Corydoras will often spawn in the community aquarium, and some of the strongest fry may survive to adulthood.

Corydoras breed somewhat differently from other types of fish. However, it is generally true that the female will attach her mouth to the genital organ of the male and will ingest the sperm. The sperm will then move swiftly through the digestive system and be expelled, together with her eggs, through a pouch formed by her pelvic fins. After ingesting the sperm, the female will move away from the male and lay her eggs in an area of her choosing.

If you plan on breeding Corydoras, then it is recommended that you set up a separate breeding tank. The breeding tank can be empty, but it would be best if you used a soft substrate as your Corydoras will prefer to feed by foraging in the substrate for food, and the female will lay her eggs there. In addition, the water should have moderate aeration, bearing in mind that Corydoras do not enjoy still water.

You will know when a female is getting ready to spawn as you will see her cleaning the surface of leaves or the aquarium glass. The female will generally hold 2 to 4 fertilised eggs between her pelvic fins then deposit these eggs in one of the areas she has been previously prepared. The process will continue until the female has run out of eggs. Females can lay up to 100 eggs during a single spawning, and after the eggs have been laid, the adults will take no part in rearing their offspring and may consume the eggs if given a chance. Therefore you should remove the adults.

The eggs will usually hatch between 1 and 3 days later depending on the water conditions and temperature, then two to three days after that, the yolk sacs will be depleted, and the fry will become free-swimming.
