How to Identify Adolfo's Corydoras

To identify Adolfo's Corydoras (Corydoras adolfoi), look at these key features.

Physical Characteristics

Body shape

rounded

Coloration

The body is primarily a light tan to yellowish-brown. A striking orange to reddish-orange band extends across the top of the head, from eye to eye. A prominent black stripe runs from the dorsal fin origin along the upper flank to the caudal peduncle. The dorsal fin itself has a black blotch or stripe. The ventral side is whitish. Fins are generally hyaline (clear) with some faint patterning on the caudal fin.

Scale type

none

Mouth position

inferior

Distinctive features

Orange/reddish-orange band across the head, Black stripe along the upper body and dorsal fin, Two pairs of maxillary barbels and one pair of mental barbels used for foraging, Armored plates (scutes) covering the body instead of scales

Dorsal fin

Single dorsal fin with a strong, serrated spine and several soft rays. The spine can be locked upright as a defense mechanism.

Tail fin

Forked caudal fin, typically with some faint patterning.

Pectoral fin

Pectoral fins possess a strong, serrated spine, similar to the dorsal fin, which can also be locked.

Distinctive fins

Adipose fin present, typical of Callichthyidae, often with a small black spot.

Identification Tips

1. 1

   Head coloration

   Look for the distinct bright orange or reddish-orange band across the top of the head, between the eyes. This is the most reliable distinguishing feature.

2. 2

   Body stripe

   Observe the black stripe that runs from the base of the dorsal fin along the upper flank to the caudal peduncle. This stripe is usually well-defined.

3. 3

   Dorsal fin marking

   Note the black marking or blotch on the dorsal fin, which is continuous with the body stripe.

4. 4

   Size

   Adults typically reach a maximum standard length of about 5-6 cm (2-2.4 inches).
