How to Identify Three-barred Peacock Bass

To identify Three-barred Peacock Bass (Cichla piquiti), look at these key features.

Physical Characteristics

Body shape

torpedo

Coloration

Base coloration varies from olive-green to golden-yellow, often with a bluish sheen, especially on the head and fins. Characterized by three prominent, dark, vertical bars on the flanks. A distinct black ocellus (eyespot) with a golden halo is present on the caudal peduncle. Fins are typically dusky or bluish, sometimes with red or orange accents, particularly in the caudal fin. Males often develop a pronounced nuchal hump (forehead bump) during breeding season.

Scale type

ctenoid

Mouth position

terminal

Distinctive features

Three prominent vertical bars on the body, Black ocellus (eyespot) on the caudal peduncle, Bluish coloration on the head and fins, especially in males, Pronounced nuchal hump in mature males, Large, predatory mouth

Dorsal fin

Long, continuous dorsal fin, with a spiny anterior portion and a soft-rayed posterior portion. The spiny part typically has 15-17 spines, and the soft-rayed part has 10-12 rays.

Tail fin

Large, rounded to slightly emarginate caudal fin.

Pectoral fin

Well-developed, rounded pectoral fins.

Distinctive fins

Pelvic fins are thoracic. Anal fin is relatively short with 3 spines and 7-9 soft rays.

Identification Tips

1. 1

   Vertical Bars

   Look for three distinct, dark vertical bars on the flanks. These bars are generally well-defined and extend from the dorsal to the ventral side of the body.

2. 2

   Caudal Ocellus

   A prominent black spot (ocellus) encircled by a golden or yellowish ring is present on the base of the caudal fin (tail fin). This is a key identifying feature for all Cichla species, but its specific appearance can help differentiate.

3. 3

   Coloration

   Observe the overall body color, which often has a bluish or greenish tint, especially on the head and fins. This blue coloration is more pronounced in males and during breeding.

4. 4

   Nuchal Hump

   Mature males, particularly during spawning, develop a noticeable fatty hump on their forehead (nuchal hump). This feature is less pronounced or absent in females and juveniles.

5. 5

   Meristics

   Fin ray and spine counts can be used for definitive identification, though this requires careful examination. C. piquiti typically has 15-17 dorsal spines and 10-12 dorsal soft rays.
