How to Identify Bolivian Ram

To identify Bolivian Ram (Mikrogeophagus altispinosus), look at these key features.

Physical Characteristics

Body shape

compressed

Coloration

The body is typically a silvery-tan to yellowish-brown, often with iridescent blue or green scales, particularly on the flanks. A prominent black spot is located centrally on each flank, and a black stripe runs vertically through the eye. Fins are often edged with red or orange, especially the dorsal and caudal fins. The pelvic fins can be bright red or orange. Breeding individuals exhibit intensified coloration.

Scale type

ctenoid

Mouth position

terminal

Distinctive features

Prominent black spot on the flank, Black stripe through the eye, Red/orange edging on fins, Relatively high-bodied compared to other Mikrogeophagus species

Dorsal fin

Long and continuous, with 14-16 spines and 9-10 soft rays. The anterior rays are often elongated, especially in males.

Tail fin

Rounded to slightly emarginate, often with red or orange coloration.

Pectoral fin

Small and clear.

Distinctive fins

Pelvic fins are elongated and often brightly colored (red/orange).

Identification Tips

1. 1

   Body Shape and Size

   Look for a relatively high-bodied, compressed cichlid, typically growing up to 6-8 cm (2.4-3.1 inches) in total length.

2. 2

   Coloration and Markings

   Identify the distinct black spot on the mid-flank and the black vertical stripe through the eye. Note the iridescent blue/green scales and the red/orange fin edgings.

3. 3

   Fin Morphology

   Observe the elongated anterior dorsal fin rays (more pronounced in males) and the often brightly colored, elongated pelvic fins.

4. 4

   Behavior

   They are generally peaceful and often seen sifting through the substrate for food, a characteristic behavior of Mikrogeophagus species.
