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 A.
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: 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. Etymology: The epithet azaghal
refers to a fictional character within the fantastic
universe created by the South African/British writer,
poet, philologist, and academic, John Ronald Reuel
Tolkien (1892-1973). Azaghâl was the king of
the Broad-beam Dwarves, one of the seven dwarf clans,
and Lord of the dwarven realm of Belegost in the Blue
Mountains during Middle Earth's First Age. The name
comes from a double allusion, first about the region
where the species was found, Terra do Meio, freely
translated as Middle Earth in English, name of the
fictional world of Tolkien's legendarium, and second
by the fact that the new species occurs in a mountainous
region and presents a relatively small size, which
are both typical features of the fictional dwarves.
