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. Aquarium Care:
Aspidoras rochai 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. Diet:Flake, tablet foods, small live and frozen
foods. Remarks: Many species of Aspidoras
are difficult to tell apart unless there is catchment
information available. As far as can be ascertained
this species has never been seen in the hobby. (2012).
The first specimen pictured is similar to the original
description of several light rounded spots on operculum
and flanks although R.von Ihering stated that he could
not give a full description of the lecotype and the
paralectotype owing to the damage to the dorsal and
caudal fin which was completely missing as shown in
the second image, which is the Lecotype.
Further Remarks: 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".
