Common name: Arabian angel
available through www.itis.gov
Identification: The body of the adult Arabian angelfish is dark overall with a broad, vertical yellow marking along the middle of the body that resembles a crescent. The dorsal and anal fins are dark and end in filaments that extend beyond the caudal fin; the caudal fin is solid yellow. Juvenile Arabian angelfish look distinctly different from the adults. The body of juveniles is blue-black with a series of narrow white and pale-blue bars; there are usually three distinct white bars. Grows to 40 cm TL. Dorsal fin XII (19-20); anal fin III (18-20); pectoral rays 17 or 18. From Randall (1983) and Allen et al. (1998).
Similar species: The rock beauty (Holacanthus tricolor) has a yellow head and tail with black body. Juvenile queen angelfish (Holacanthus ciliaris) and blue angelfish (Holacanthus bermudensis) have bright blue body bars. Juvenile French angelfish (Holacanthus paru) and gray angelfish (Holacanthus arcuatus) have bright yellow body bars on black body.
Size: 40.0 cm TL.
Native Range: Western Indian Ocean, from the Red Sea and Gulf of Aden south to Zanzibar (Randall 1983, Allen et al. 1998).
In Florida, this species has been observed/photographed near Boca Raton (in 1995 and 2002 [Courtenay 1995, REEF 2008]) and off Dania Beach (in 2001 [Semmens et. al 2004, REEF 2008]). One individual was observed at each sighting.

Ecology: In their native habitat, Arabian angelfish live along shallow (3 to 15 m depth), protected shoreline reefs with a mix of hard and soft corals. The species has been noted as shy, and not easy to approach. Generally it is observed near caves or crevices along the reef, and rarely ventures far from these refugia. Feeds primarily on sponges and tunicates. From Allen et al. (1998).
Means of Introduction: Probable aquarium release.
Status: Reported in Florida.
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.
