Mouth position

terminal

Distinctive features

Robust body shape typical of Mbuna cichlids, Prominent vertical barring on flanks (more pronounced in males), Sexual dimorphism in coloration, Relatively large eyes

Dorsal fin

Long and continuous, with spiny anterior rays and soft posterior rays. Often edged in a contrasting color in males.

Tail fin

Truncate to slightly emarginate, often with ocelli (egg spots) in males.

Identification Tips

1. 1

   Coloration (Males)

   Look for a bright blue body with distinct vertical black bars. The dorsal fin often has a light blue or white margin. The intensity of blue and black can vary.

   Coloration (Females)

   Females are generally less colorful, often appearing brownish-grey or light blue with fainter barring. This sexual dimorphism is a key identifier.

3. 3

   Body Shape

   Typical robust, compressed body shape of Mbuna cichlids. Compare with other Maylandia species for subtle differences in body depth and head profile.

4. 4

   Geographic Origin

   Knowing the collection point (Usisya) is crucial for accurate identification, as many Mbuna species are geographically isolated and morphologically similar.
