Similar to C.
adolfoi but adolfoi has a thinner black
back stripe and its pectoral fin spine is not serrated as in C.
duplicareus. There are instances where the body stripe on
C. duplicareus is thinner but it usually has a higher
backed body form than C. adolfoi. Aquarium Care:
A minimum sized tank of 24” x 15” X 12” for
a small shoal. Good quality aquarium sand such as BD Aquarium
Sand, or very smooth rounded gravel as the preferred substrate
when keeping these catfish. The aquarium should provide some shelter
in the form of rocks or bogwood along with some aquatic plants.
As with all other species of fish, water quality and general husbandry
is very important, and recommended is that a minimum of 25% water
is changed on a weekly to fortnightly basis. Diet:
Readily accepts a mixed and varied diet which includes granular
foods, frozen bloodworm and good quality flake to name but a few.
