C. amapaensis is one of only four species that posses a third pair of rictal barbels, C. septentrionalis, C. geoffroy and C. simulatus are the other three. These extra barbels are short and not that easy to see unless the fish is stationary. There are two populations of C. amapaensis with their own colour patterns and they may overlap. Habitat: Found in small creeks with flowing water and sandy bottom, in the upper reaches of rivers, upstream of the first rapids. Sympatric with C. solox. Lineage: Placed it in Lineage 1. and when there is a revision they will stay as Corydoras (Lacépède, 1803) with the type species of C. geoffroy La Cépède, 1803. Aquarium Care: As this is one of the longer snouted species it will be well suited to most community tanks. A well planted tank with a soft substrate such as sand so they can bury their snouts while searching out food. Diet: Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and good quality flake to name but a few. Etymology: The specific name amapaensis: from Amapa, the state in Brazil where this Corydoras species was found and ensis = denoting place, locality, country. Remarks: The fish collected in the Oyapock River in the border river between French Guyana and Brazil is likely to be a colour variety of C. amapaensis.
