Aspidoras brunneus can be distinguished from
all of its congeners by having a wide, longitudinal,
conspicuous dark brown stripe along dorsal portion
of flank (vs. absence of such stripe). Additionally,
it can be distinguished from A. aldebaran,
A. belenos, A. depinnai, A.
fuscoguttatus, A. maculosus, A.
poecilus, A. psammatides, A. raimundi,
and A. rochai by having nuchal plate entirely
covered by a thick layer of skin (vs. nuchal plate
with at least posterior portion exposed). The Aspidoras
genera differ from Corydoras by their different
behaviour such as their swimming habits (Tencatt
et al.). The
eyes are smaller, body smaller and a smaller head
shape in Aspidoras compared with Corydoras.
Aspidoras posses a duel fontanel bone structure
in the skull whereas Corydoras have only the
one larger fontanel. All Aspidoras belong
to Lineage 2 with the exception of
will prove to be a Corydoras and if a revision
is carried out will be Gastrodermus (Cope,
1878) and a member of Lineage 5 alongside members
of the "elegans group". Aquarium
Care: Aspidoras brunneus is fairly
uncommon in the hobby but as with all of this genus
they are best kept in groups of six or more and are
best housed with small fishes that are not aggressive.
Provide a planted area in the tank for cover and include
a soft substrate such as sand or small rounded gravel.
foods, small live and frozen foods. Many species of
Aspidoras are difficult to tell apart unless
there is area catchment information available.
