Alexander's Damsel, Pomacentrus alexanderae (Evermann & Searle, 1907)
Alexander's Damsel is small, light grey fish that lives in lagoons and on both inshore and offshore coral reefs.
Alexander's Damsel is light grey with a black pectoral fin base. It looks similar to a number of other damselfish species but can be distinguished by a combination of characteristics that include body dimensions, counts of fin rays, scales and gill rakers.
It is usually seen at depths between 5 m and 30 m in lagoons and on both inshore and offshore coral reefs.
Alexander's Damsel occurs in tropical marine waters of the Eastern Indian Ocean and Western Pacific. In Australia it is known from north-western Western Australia.
