G. pauciradiatus has
6 soft rays in the dorsal while the rest of the genus
has 7, (pauciradiatus means, few fin rays).
It is still valid in some aspects of the scientific
community as Aspidoras pauciradiatus but
it is certainly a Corydoras. Lineage:When it is reclassified it will be placed in
Lineage 5 the "Elegans group". A revision
could involve the resurrection of the genus name
Gastrodermus (Cope, 1878) with the
designated type species of C. elegans. As
of the latest update Corydoras pauciradiatus
has now been placed in Lineage 5 and has the new genus
name of Gastrodermus (2024).
Aquarium Care: Gastrodermus pauciradiatus
does not do well in a mixed community tank with larger
tankmates due to its size and retiring nature. A better
idea is a smaller tank with small characins/tetras
or even a tank on their own. Buy at least 6 or more
as they do better in their own company and when settled
will come to the front of the tank at feeding time.
I find that Java Moss and Java Fern plants with a
sand substrate and a box or sponge filter in a 18"
x 12" x 12" tank will keep them happy, with
weekly water changes of 30 to 50% adequate. Diet:
A good quality flake food and tablet food for adults
with sporadic feedings of small frozen or live food
will keep your Corydoras/Gastrodermus in
good health. Etymology: The specific
name pauciradiatus:
With few (fin) rays (6 rays in dorsal). Remarks:
Still found on some online sources as Corydoras
pauciradiatus.
