Southern Demoiselle

Chrysiptera notialis

The Southern Demoiselle is a small reef-associated fish found in the subtropical waters of the Western Pacific, specifically around Lord Howe Island, Norfolk Island, and New Caledonia. It inhabits outer rocky reefs, typically at depths ranging from 7 to 45 meters. This species is characterized by its fusiform, compressed body shape, and can grow up to 9 cm in total length. It has 13 dorsal spines, 14 to 15 dorsal soft rays, 2 anal spines, and 15 to 16 anal soft rays. The Southern Demoiselle is oviparous, with distinct pairing during the breeding season. The eggs are demersal, meaning they adhere to the substrate, and males play a crucial role in guarding and aerating them. This species is non-migratory, making it a consistent presence in its preferred habitats. Divers encountering the Southern Demoiselle can expect to see it dwelling among the rocky reefs. The Southern Demoiselle is not evaluated by the IUCN for conservation status.
