Miller's Damsel

Pomacentrus milleri

Miller's Damsel, a member of the Pomacentridae family, is a small reef-associated fish found in the Eastern Indian Ocean, particularly around northern Australia from Rottnest Island to Arnhem Land. Divers can spot this species in shallow waters, typically between 1 and 6 meters deep, where it inhabits inshore reef areas, often seen around dead coral. It has a fusiform body shape with a compressed cross-section, and features 13 to 14 dorsal spines and soft rays, along with 2 anal spines and 13 to 14 anal soft rays. This species is diurnal and non-migratory, making it a consistent presence in its habitat. Miller's Damsel is oviparous, with distinct pairing during breeding. The eggs are demersal, adhering to the substrate, and the males take on the role of guarding and aerating the eggs. For divers encountering Miller's Damsel, it is a harmless species, allowing for close observation. The IUCN has assessed this species as Least Concern. Observing its behavior, particularly during breeding, can provide interesting insights into its reproductive strategies.
