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: flaming angelfish

Synonyms and Other Names: flame angelfish

Taxonomy: available through www.itis.gov

Identification: Randall (2005) describes this species as brilliant orange-red in color, shading to orange-yellow in the middle of the body, typically with a vertically elongate black spot behind the pectoral fin and 5 black bars on rest of body; small black spots often present on the dorsal fin; dorsal and anal fins bright orange-red, the posterior part is black with blue or purple streaks; caudal fin with light orange-yellow rays and transparent membranes; and the pelvic fins orange-red. The horizontal blue streaks on the dorsal and anal fins are more pronounced in males (Allen et al. 1998).

Size: up to 10 cm total length (Randall 2005)

Native Range: Widespread scattered localities throughout the western Pacific from Palau to Marquesas, Hawaiian Islands, southward to the Great Barrier Reef. Most common in Palau, Caroline, Marshall, and Society Islands (Allen et al. 1998).

Ecology: Centropyge loriculus inhabits rich coral areas on seaward and lagoonal reefs from 5-60 m deep (Allen et al. 1998). The species is herbivorous, feeding primarily on benthic algae and detritus (Randall 1996). It exhibits secretive behavior staying close to areas of shelter (Allen et al. 1998). Centropyge loriculus is a protogynous hermaphrodite, starting life as female and later changing sex to become a male (Randall 2005). Males of this species maintain a harem of two to several females in its territory (Randall 2005). Spawning typically occurs at dusk (Randall 2005). Maturity is reached in 1-2 years (Allen et al. 1998).

Means of Introduction: probable aquarium release

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.

Remarks: Centropyge loriculus are very popular in the marine aquarium fish trade (Allen et al.1998, Wabnitz and Nahacky 2015).

Color patterns are often used as the diagnostic character to determine species within this genus. Most populations of Centropyge loriculus have the typical coloration with small black spots scattered across the dorsal and anal fins and is known as the ‘orange morph’ (Schultz et al. 2007). In Hawaii, this species is bright red with a reduced number of black markings and is referred to as the ‘red morph’ (Schultz et al. 2007). In the Marquesas Islands this species has almost no black coloration on the body and is known as the ‘Marquesan morph’ (Schultz et al. 2007). The color morph of the individual recorded from Hawaii in Kane’ohe Bay does not have the distinctive color pattern of the native Hawaiian ‘red morph’ suggesting possible aquarium release (Mundy 2005).
