How to Identify Green Terror Cichlid

To identify Green Terror Cichlid (Andinoacara rivulatus), look at these key features.

Physical Characteristics

Body shape

compressed

Coloration

Base body color ranges from grey to olive-green, often with iridescent green-blue scales, particularly on the flanks and operculum. A prominent black spot is typically present on the mid-flank, and another at the base of the caudal fin. The fins are often edged with a vibrant orange, white, or gold band (hence 'Gold Saum' or 'White Saum'). Males exhibit more intense coloration and a more pronounced nuchal hump, especially when mature and breeding.

Dorsal fin

Long and continuous, often with a vibrant colored margin, especially in males.

Tail fin

Fan-shaped to rounded, typically with a colored margin matching the dorsal and anal fins.

Pectoral fin

Clear to slightly yellowish, relatively small compared to body size.

The caudal, dorsal, and anal fins often have a striking orange, white, or gold band along their edges, which is a key identifying feature and contributes to its common names.

Identification Tips

1. 1

   Coloration and Iridescence

   Look for the characteristic iridescent green-blue sheen on the body, especially under good lighting. This is a primary differentiator from other 'terror' cichlids.

2. 2

   Fin Margins

   Observe the distinct orange, white, or gold banding on the dorsal, caudal, and anal fins. The intensity and color of this banding can vary but is a consistent feature.

3. 3

   Body Spots

   Identify the two prominent black spots: one on the mid-flank and another at the base of the caudal fin. These are usually quite clear.

4. 4

   Nuchal Hump (Males)

   Mature males will often develop a noticeable fatty hump on their forehead, which becomes more pronounced during breeding periods. This is a strong indicator of sex and maturity.

5. 5

   Body Shape and Size

   Note the robust, compressed body shape. Males grow significantly larger than females.
