technically emerald corys are not corys. They are brochis splendens, a cousin. While similar, brochis can be differentiated from corys by their dorsal fins. Corys have seven or eight dorsal rays, and have a considerable gap between the their dorsal fin and the adipose fin. Brochis, on the other hand, have like 14 dorsal rays - their dorsal fin extends almost all the way back to the adipose fin.
The "cory" complex is comprised of corydoras, aspidoras, and brochis.
