[Ebook] 500 freshwater aquarium fish – Catfish – False Corydoras (Aspidoras pauciradiatus)
Both the first common name and the synonym for this species indicate just how closely Aspidoras and Corydoras species catfish are related to each other. The main distinguishing skeletal feature between the two — but one that cannot be observed in living specimens—is the number of cranial fontanels (skull pores, openings, or “holes”): Aspidoras sp. has two, while Corydoras sp. and Brochis sp. have one. The False Corydoras is a delightful species, liberally speckled in black and with a distinctive black blotch on the dorsal fin.
