Relevant Information:

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. C. pauciradiatus has 6 soft rays in the dorsal while the rest of the genus has 7, (pauciradiatus means, few fin rays). Aquarium Care: Corydoras 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 in good health.
