Flame Angelfish

The Flame Angelfish (Centropyge loricula) is a dwarf angelfish in the family Pomacanthidae, widely distributed across the tropical Pacific Ocean. It is one of the most brightly colored small reef fishes, instantly recognizable by its fiery orange-red body and bold black barring. Flame Angelfish are common on reef flats and slopes across a broad range from Indonesia and the Great Barrier Reef east to Hawaii and French Polynesia. They belong to the genus Centropyge, the pygmy or dwarf angelfishes, which are generally smaller and less territorial toward divers than their larger angelfish relatives. The species is not considered at risk and remains abundant throughout its natural range.

The Flame Angelfish is identified by a combination of features:

• Bright orange-red body, deep and laterally compressed, growing to 8-10 cm
• Five to six dark vertical bars crossing the mid-body
• Blue-black margins and streaks on the dorsal and anal fins
• Rounded fins and a small terminal mouth typical of dwarf angelfishes

Color intensity and bar pattern vary somewhat by locality, with Marquesan populations showing more extensive black on the body. It can be distinguished from other similarly colored dwarf angelfish by the combination of vivid orange-red base color with blue-edged vertical fins.

Flame Angelfish inhabit coral-rich reef slopes, lagoons, and rubble areas throughout the tropical Pacific, from Indonesia and the Great Barrier Reef eastward to Hawaii, the Line Islands, and French Polynesia. They are typically found at depths of 3 to 60 meters, most commonly in the shallower range where branching coral and rubble provide cover. They prefer areas with abundant hiding spaces among coral rubble and live rock, in water temperatures generally between 24-28°C. They are absent from turbid or heavily silted environments, favoring clear, well-oxygenated reef water.

Flame Angelfish are typically solitary or found in small harems consisting of one male and several females, defending a shared territory among coral rubble. They are protogynous hermaphrodites, with females able to change sex to male when needed to maintain a harem structure. Individuals feed by picking algae from rock surfaces and opportunistically taking small zooplankton throughout the day, retreating into crevices at night or when threatened. Pair or harem spawning occurs at dusk, with pelagic eggs released into the water column to drift with currents before hatching. They are generally territorial toward other angelfish but tolerate a range of other reef species nearby.
