Flame Angelfish

The Flame Angelfish (Centropyge loricula) is a small, brightly colored marine angelfish native to the tropical Pacific Ocean. Known for its vivid red-orange body and vertical black bars, it is one of the most popular species in the aquarium trade due to its striking appearance and manageable size.

Key facts

• Scientific name: Centropyge loricula

• Family: Pomacanthidae

• Native range: Central and Western Pacific Ocean

• Typical size: Up to 10 cm (4 in)

• Conservation status: Least Concern (IUCN)

Appearance and Identification

The Flame Angelfish features a bright orange-red body with several vertical black bars on its sides and electric-blue edging on the dorsal and anal fins. Males tend to be slightly larger and may exhibit more intense coloration than females. This distinctive look makes it one of the most recognizable dwarf angelfish species.

Habitat and Distribution

Centropyge loricula inhabits coral-rich lagoons and outer reef slopes, usually at depths of 5–60 meters. Its range extends across the central and western Pacific, including areas around the Marshall Islands, Palau, Tahiti, and Fiji. These fish are often seen in small harems consisting of one male and several females.

Behavior and Diet

Flame Angelfish are active grazers that feed primarily on algae, detritus, and small invertebrates. In the wild, they contribute to reef health by controlling algal growth. In captivity, they require a varied diet that includes marine algae, spirulina, and quality frozen foods. Though generally peaceful, they may exhibit territorial behavior toward other dwarf angelfish.

Aquarium Care and Compatibility

This species adapts well to reef aquariums but may nip at corals or clam mantles. It thrives in well-established tanks with abundant live rock for grazing and hiding. Maintaining stable water quality, moderate lighting, and plenty of swimming space is essential for its health.

Reproduction

Flame Angelfish are protogynous hermaphrodites—females can change sex to become males if the dominant male is removed. Spawning usually occurs near dusk, with eggs released into the water column for pelagic development.

The Flame Angelfish’s beauty, small size, and active personality have made it a centerpiece species for marine aquarists worldwide.
