Care
Agassiz's Cory is a peaceful bottom-dwelling catfish that is ideally suited to mature community aquaria. The substrate should consist of soft sand in order to protect the delicate sensory barbels. Provide some shady retreats amongst bogwood and areas of dense planting, and keep only with small, peaceable tankmates, such as some of the smaller sized characins/cyprinids/anabantoids or dwarf cichlids. Regular maintenance, including frequent partial water changes, should be carried out in order to keep these fish in good condition. 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.
This species can be hard to differentiate from the very similar B. ambiacus, which has a white leading edge to the dorsal fin and a subtly different spot pattern. The fish imported from Peru as Corydoras punctatus Nanay is also closely related and possibly undescribed.
Recent work on the previously enormous genus Corydoras has moved this species into Brochis, reflecting a close kinship despite some differences such as numbers of dorsal fin rays and a lack of senior synonyms used for the other groups/lineages of former Corydoras species. Further studies will probably result in this fish being placed in a new genus.
Feeding
Sinking catfish pellets, frozen foods such as bloodworm, white mosquito larvae and vitamin-enriched brineshrimp.
Breeding
There are no breeding reports of this species. However, it is likely to spawn in the same manner as other Corydoras species with the pair adopting the classic T position where the male fertilises the eggs that are held between the female's pelvic fins.
