I first successfully bred and raised Corydoras amapaensis in June 1980. This spawning may very well have been the first recorded spawning of one of the long snouted Corydoras species. I have found them to be very adaptable, tolerating a variety of aquarium conditions including a wide temperature range, which can be from 68 up to 85 degrees Fahrenheit. The preferred temperature seamed to be between 70-74 degrees Fahrenheit. The one thing that they do favor is a fine substrate, I use well-washed river sand, which is smooth and rounded, a little like tiny pebbles which do not cause any damage to barbells when the fish are sifting through it in their constant search for food particles. Like all of the long snouted species Corydoras amapaensis spend a great deal of their time buried headfirst in the substrate.
