Care
The Northern Long-nosed Cory is known from the Orinoco River basin in Colombia and Venezuela. This peaceful species is ideal for the mature community aquarium, and should be maintained in groups of 5 or more due to shoaling nature. Unfortunately, it can be a little prone to barbel infections/erosion, so it is of paramount importance that the fish are kept on a soft sand substrate (rather than gravel where waste can build up unseen) in order to protect these delicate sensory organs. Regular maintenance, including frequent partial water changes, should be carried out in order to keep these fish in good condition. Provide plenty of shady areas amongst driftwood, rocks, and areas of dense planting. Other peaceful species such as some of the smaller pencilfish, tetra, and rasboras make ideal tankmates, and their presence as "˜dither fish"™ in midwater will encourage the Corydoras out into view more often. Corydoras have the ability to breathe air intestinally, so a small gap should be left between the surface of the water and the cover slides in order for the fish to come up to the surface and take air in. It may do this numerous times per day.
Feeding
Sinking catfish pellets, frozen foods such as bloodworm, white mosquito larvae and vitamin-enriched brineshrimp.
Breeding
There are currently no reports of this species having been bred in the home aquarium. However, it is likely to spawn in the typical Corydoras manner whereby following a large, slightly cool water change, a pair will adopt the classic 'T position' with the male fertilising the eggs that are held between the females' pelvic fins.
