A fairly stocky, long-snouted cory with a pale greyish body covered in small dark spots, a dark bar through the eye and a dark blotch on the dorsal fin. It is a hardy, sociable bottom dweller that suits community tanks with soft sand, and it spends its day sifting the substrate for food.

Breeding

Breeds in the typical cory T-position, with the female sticking eggs to glass, plants or decor, often after a large cool water change. It is not often bred in home aquariums, but spawning is possible with well-conditioned groups, and the eggs and fry should be raised apart from the adults.

Good to know

It is often confused with Corydoras blochi and similar spotted long-snouted species, and trade shipments are frequently mixed. Use fine sand and keep the water clean so the barbels are not damaged.
