BANDIT CORYDORA (Corydoras metae)

This species is also referred to as ‘masked’ or ‘Meta’ cory in the aquarium hobby. It can be distinguished from similar-looking congeners by the form of the oblique dark bar on the posterior portion of the body, which terminates at the caudal-fin base and does not extend onto the fin itself or split into two on the caudal peduncle. There are no additional dark markings on the body.
