How to Identify Bronze Corydoras

To identify Bronze Corydoras (Corydoras aeneus), look at these key features.

Physical Characteristics

Body shape

compressed

Coloration

The body is typically a bronze to greenish-brown dorsally, fading to a lighter, often whitish or pinkish, ventral surface. A distinct metallic sheen, particularly on the flanks, gives them their 'bronze' or 'green' corydoras common names. Some populations exhibit a darker lateral stripe or blotches, and fin coloration generally matches the body.

Scale type

none

Mouth position

inferior

Distinctive features

Three pairs of barbels around the mouth, used for foraging., Two rows of bony plates (scutes) along each flank, providing armor., Adipose fin present, characteristic of catfishes., Spiny rays in the dorsal and pectoral fins.

Dorsal fin

Single dorsal fin with one strong, serrated spine and 7-8 soft rays.

Tail fin

Forked caudal fin.

Pectoral fin

Pectoral fins with a strong, serrated spine and soft rays.

Distinctive fins

Adipose fin present, small and located between the dorsal and caudal fins.

Identification Tips

1. 1

   Body Coloration

   Look for the characteristic bronze to greenish-brown metallic sheen on the body, especially along the flanks. The belly is typically lighter.

2. 2

   Barbels

   Observe the three pairs of prominent barbels around the mouth, which are crucial for distinguishing Corydoras from other catfish genera.

3. 3

   Body Shape

   Note the relatively deep, compressed body with a slightly arched dorsal profile and a flattened ventral surface.

4. 4

   Fin Spines

   Identify the strong, serrated spines in the dorsal and pectoral fins, a key feature of Corydoras species.
