The Icana Cory, known scientifically as Corydoras incolicana and referred to in the aquarium trade as C001, is a lesser-known yet charming species of Corydoras catfish. Native to the Içana River basin in Brazil, this species is appreciated among dedicated aquarists for its subtle beauty and intriguing behavior.

Corydoras incolicana typically exhibits a gentle color palette that includes a light, sandy-colored body with darker patches or markings, which helps it blend into the soft substrates of its natural habitat. Like other Corydoras species, the Icana Cory is small and compact, with a somewhat rounded body shape and barbels near its mouth, which it uses to sift through substrate for food.

In the aquarium, Icana Corys are best kept in groups due to their social nature; they are more active and exhibit more natural behaviors when housed with several of their kind. They are peaceful and well-suited to community tanks with other non-aggressive fish. The ideal aquarium setup for Corydoras incolicana should include a soft, sandy substrate to protect their sensitive barbels, along with plenty of hiding spots such as plants, rocks, and driftwood. They appreciate a setup with clean, well-oxygenated water and a gentle current.

The diet of the Icana Cory should be varied and nutritionally balanced, including high-quality sinking pellets or tablets, supplemented with live and frozen foods like bloodworms, brine shrimp, and daphnia. Vegetable matter can also be included occasionally to provide a well-rounded diet.

Breeding Corydoras incolicana can be achievable with careful attention to their environmental conditions. They are typical egg layers, where the female deposits eggs on the aquarium glass, vegetation, or decor after a unique "T-position" mating dance with the male. To encourage spawning, some aquarists perform water changes with slightly cooler water to mimic the natural increase in water flow and change in temperature that often triggers breeding in the wild.

Conservation considerations for Corydoras incolicana are important as their native habitats may be threatened by environmental changes and pollution. Maintaining sustainable aquarium trade practices and promoting habitat preservation are crucial for the survival of this and similar species.

Overall, the Icana Cory is a delightful addition to any freshwater aquarium, especially for those who appreciate the gentle nature and communal behaviors of Corydoras. Their care requirements are manageable, making them a suitable choice for both novice and experienced aquarists who wish to enjoy the subtleties of a less common Corydoras species.
