The Aspidoras genera
differ from Corydoras by their different
behaviour such as their swimming habits. 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. Many species of Aspidoras
are difficult to tell apart unless there is catchment
information available. 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 poecilis 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.
