Relevant Information:

This is one of the few Aspidoras that can be readily identified by its conspicuous markings. It has also 6 soft rays in the dorsal while the rest of the genus has 7. ( pauciradiatus means, few fin rays). Most other Aspidoras species tend to have a brown colouration with a scattered spotted pattern which can lead to identification problems. Aquarium Care: Aspidoras 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. Remarks: this species in the future will probably be shifted back to the Corydoras genera and as being in lineage 2 now (Aspidoras) it will be assigned to lineage 5 the "Elegans group" (Gastrodermus)
