Disclaimer:

The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Common name: Regal angelfish

Taxonomy: available through www.itis.gov

Identification: Dorsal rays XIV (17-19); anal rays III (17-19); pectoral rays 16-17; longitudinal scale series 48-50 (Randall 2005).

Size: to 25 cm (Randall 2005).

Native Range: Indo-Pacific from South Africa and the Red Sea to Indonesia, northern Australia, New Caledonia, southern Japan, Micronesia to the Gilbert Islands, and French Polynesia.

Interactive maps: Point Distribution Maps

Ecology: Occurs from shallow protected reefs in bays and lagoons to outer-reef areas at depths of at least 50 m.  Feeds mainly on sponges.  Juveniles are cryptic, hiding in caves (often upsided down on roof).  Indian Ocean population with distinct colouring, but not yet given nomenclatural recognition.  From Randall (2005).

Means of Introduction: Probable aquarium release

Status: Collected in Hawaii.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
