Phoenix Damsel

Plectroglyphidodon phoenixensis

Phoenix Damsels are small reef fish reaching up to 9 centimeters in length. They are characterized by their distinct body shape, which is short and deep with an oval cross-section. These fish are equipped with 12 dorsal spines, 16 to 17 dorsal soft rays, 2 anal spines, and 13 to 14 anal soft rays. Phoenix Damsels are solitary and territorial, typically found in the surge zones of seaward reef margins. They inhabit regions from East Africa to the Marquesas Islands, including the Society and Tuamotus Islands, and north to the Ryukyu Islands. These fish prefer habitats in or near coral patches, particularly those of Acropora or Pocillopora, at depths ranging from 1 to 8 meters. As herbivores, they primarily feed on benthic algae, playing a role in maintaining the balance of the reef ecosystem. Phoenix Damsels are oviparous, laying eggs that adhere to the substrate. Males take on the responsibility of guarding and aerating the eggs, ensuring their development. Divers encountering Phoenix Damsels may observe them in shallow reef areas, where they are active during the day. Despite being fairly rare within their native range, their conservation status is listed as Least Concern. The primary threat to their population is their collection for the aquarium trade, although this is not considered significant.
