Astroblepids are closely related
to the Loricariids, and in fact one genus of fish
(Lithogenes Eigenman, 1909) seems intermediate
between the two families, having the shape and form
of an Astroblepid, but some plates on the body and
other morphological characters closer to Loricariids.
At the time of writing, Lithogenes is currently
placed in Loricariidae. Description:
Vertebrae: 24, premaxilla with 0-1 bicuspid teeth
and 6-10 conic teeth in external row, 7 soft radii,
and 24 vertebrae. Astroblepus ardiladuartei
is recognised among the other species of the genus
by the lack of an adipose fin in adults. Habitat:
Fishes of the family Astroblepidae are found in freshwaters
streams (between 200 to 13,400 feet above sea level)
of the tropical Andes from Panama to Bolivia, and
occur in both the western Pacific and eastern Amazonian
slope drainage systems in South and Central America.
Colouration: The head is a light
brown colour with two large vertical patches of dark
colour to each side of the nostrils, black eyes. Oral
disc medium (7.1-13.2 mm). Lateral region of the body
with background light brown and dark brown irregular
blotches. Caudal fin with a vertical band broadband
light brown colour at the base and spokes without
stripes; the first simple spokes are the same and
a little long. Abdomen pale brown. Aquarium
Care: Not an easy family of catfishes to
keep so they would have to have a large tank with
rocks and some appropriate vegetation. The water would
need to be fast flowing and provided with extra oxygen
via an air tube fed into the powerhead flow. The tank
should be set up with rocks so as to provide an area
where the water current will be slower. Diet:Invertebrates, insect larvae, spirulina tablets
or paste, algae based foods and live bloodworm would
probably be the staple diet but you may wish to try
glassworm and blackworm (although these won’t
tend to stay on the substrate unless the current takes
them there). Etymology: The specific
name is a tribute to the authors son, biologist Carlos
Alfonso Ardila Duarte, with whom they collected this
species in its type locality.
