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.
