C. amapaensis is
one of only four species that posses a third pair
of rictal barbels, C.
geoffroy and C.
simulatusare 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.
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. 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.
Oyapock and Amapari rivers in Amapá State in
Brazil and French Guiana. Type locality:
Brazil, Est. Amapa, Cachoera Creek at right bank of
Río Amapari, 4 km downstream of Casa do 7.
