What is the genus and species for Corydoras?

This base group of “saddle-nosed” species should remain as Corydoras, as first described by Lacépède in 1803. The type species for the genus will remain Corydoras geoffroy. Long snouted species such as Corydoras fowleri are at the base of the Corydoradinae group. Example species below: Aspidoras cf. spilotus.

Is Corydoras petracinii related to Aspidoras?

All known Aspidoras belong to this lineage apart from A. pauciradiatus. Both Corydoras gladysae (Lineage 6) and Corydoras petracinii (Lineage 6) seem more closely related to Aspidoras, but they lack certain traits defining Aspidoras. They might therefore require a new generic name (Calvino and Alonso, 2009).

Can two different species of Corydoras coexist together?

The phenomenon of multiple, similarly-coloured species which coexist and school together is relatively common in the genus, although it is typically displayed by sympatric Corydoras species with only a few examples in which such patterns have evolved in other taxa.
