Relevant Information:

This small species is similar to G. mamore from the Rio Mamore but this Corydoras/Gastrodermus has a black dorsal blotch. Lineage: Placed in Lineage 4 which includes two of the dwarf species and a revison would be a resurrection of the disused Microcorydoras (Myers, 1953) with the designated type species: C. hastatus. As of the latest update Corydoras paucerna has now been placed in Lineage 5 and has the new genus name of Gastrodermus (2024). Aquarium Care: This is akin to most of this genus, very peaceful, and would be best housed with small to medium sized tankmates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Best to purchase 6 individuals or more as they will be happier in a group. Diet: Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and a good quality flake. Etymology: The specific name paucerna: Named for the river this Gastrodermus comes from, the Rio Paucerna. Remarks: Still found on some online sources as Corydoras paucerna.
