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:
This species is distinguished by the following characters:
no spine on adipose fin; maxillary barbel extending
beyond the oral disk; first pectoral radius longer
than head longitude; soft branching radii 8; first
radius of pelvic fin beyond the anus; premaxillary
with 1-2 bicuspid and 6-7 conical teeth in the outermost
row; first simple radii of caudal fin no extension;
fifth cerato-branchial bone with 8 teeth; free vertebrae
26. Cross section: oval.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.
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 huallagaensis: Named for
its type locality, R ío Huallaga (Perú,
elevation 997 m). Remarks:
There is a phenotypic variability and variations in
colouration pattern with this species.
