Key identification features

- High, arched back with a downturned, whiskered mouth bearing two pairs of barbels
- Base color ranges from olive-brown to bronze-green with a metallic gold-to-green sheen along the flank
- Rounded snout and small subterminal mouth adapted for sifting substrate

Common look-alikes
- Peppered Corydoras (Corydoras paleatus) shows a dark, irregular mottled or "peppered" pattern instead of the Bronze's smooth metallic sheen.
- Corydoras sterbai has bright orange-tipped pectoral and pelvic fins and a spotted body, unlike the Bronze's solid flank coloring and plain fins.
- Albino Bronze Corydoras is the same species and shape but lacks pigment, appearing pink-white with red eyes.
Where you'll see one

Frequently asked questions
How do I tell a Bronze Corydoras from a Peppered Corydoras?
Look at the pattern: Bronze Corydoras has a smooth, uniform metallic olive-gold sheen, while Peppered Corydoras shows a busy, dark mottled or speckled pattern over a grayish body.
What is the easiest feature to spot a Corydoras catfish by at a glance?
The paired barbels around the downturned mouth combined with the armored, bony-plated body are the quickest giveaways that you're looking at a Corydoras rather than another small catfish.
