How to Identify Peacock Cichlid

To identify Peacock Cichlid (Aulonocara), look at these key features.

Physical Characteristics

Body shape

compressed

Coloration

Males exhibit vibrant, iridescent colors including blues, yellows, reds, and oranges, often with metallic sheens and distinct patterns (e.g., vertical bars, spots). Females are typically duller, brownish-grey with faint vertical bars.

Scale type

ctenoid

Mouth position

terminal

Distinctive features

Sensory pores on the head and lateral line system, particularly prominent on the lower jaw, used for detecting invertebrates in the sand., Males possess egg spots on the anal fin, which play a role in breeding., Relatively large eyes compared to some other cichlid genera.

Dorsal fin

Long, continuous dorsal fin with spiny anterior rays and soft posterior rays. Males often have extended finnage.

Tail fin

Caudal fin is typically rounded to slightly emarginate.

Pectoral fin

Paired pectoral fins are well-developed.

Distinctive fins

Pelvic fins are often elongated in males, sometimes with filamentous extensions.

Identification Tips

1. 1

   Male Coloration

   The most striking feature for identification. Each Aulonocara species has a unique male color pattern. For example, A. jacobfreibergi often has blue bodies with yellow dorsal and caudal fins, while A. stuartgranti 'Ngara Flametail' has a blue body with a prominent orange-red tail.

2. 2

   Sensory Pores

   Look for the distinctive enlarged sensory pores on the lower jaw and head, which are characteristic of the genus and aid in detecting prey buried in the sand.

3. 3

   Body Shape

   Generally compressed, somewhat elongated bodies, typical of many haplochromine cichlids, but often more streamlined than Mbuna.

4. 4

   Female Appearance

   Females are much less colorful, usually greyish-brown with faint vertical bars. Identification to species level based solely on females is often challenging without genetic analysis or association with known males.
