Groupements:

• Habitat: Lacs : intermédiaire

Étymologie: margarita + ferre = I bear pearls.

Types: Known from one 20 centimeter (8 inches) preserved specimen in the British Museum of Natural History.

Diagnose: Most closely related to the Amphilophus species group.

Taille: Up to 8 inches.

Dimorphisme sexuel: Males may have spots on the unpaired fins, while females are clear..

Localité type: Lago Petén, Guatemala.

Distribution: Most likely the Rio Maria Linda drainage, including the former lakes under the Guatemala City and Lago Amatitlan, and other smaller coastal drainages to the east of Iztapa. May be present in Laguna de Calderas near Santa Elena de Barillas. Possibly introduced to the higher elevation lakes as early as the 1500s by Spanish priests..

Répartition par pays: Guatemala (endemic).

Biotope: Lakes and coastal rivers. Lago Amatitlan is severely polluted, and the Rio Maria Linda receives untreated effluent from Guatemala City and Escuintla. .

Localités: Lake Petén-Itza (Guatemala, native).

Alimentation: Data not available but closely related to A. macracanthus..

Reproduction: Unknown.

Conservation: Astatheros margaritifer est évalué par l'Union Internationale pour la Conservation de la Nature dans la Liste Rouge des espèces menacées comme étant (EN) Menacée (2009). Lago Amatitlan, where one specimenwas captured, is undergoing severe eutrification, and could fill with sediment within 100 years. Coastal rivers run through areas with ranches and agriculture..

Commentaires: Long one of the great mysteries of Central American cichlids, the capture in 2011 of a single specimen in Lago Amatitlan raised as many questions as it answered. May have been common in the area around Guatemala City in the 1860s when Godman and Salvin visited. Those lakes have disappeared. However, regular volcanic eruptions likely caused loss of aquatic life in the area, leading the Spanish to stock Amatitlan and Atitlan with fish. Rosen and Bailey report capturing them with A. macracanthus, A. trimaculatus, and A. nigrofasciatus in coastal rivers. It is suspected that is how cichlids came to be found at such high elevations..
