Centropyge boylei, commonly known as the Peppermint Angelfish, is a small, vibrant marine fish known for its striking red and white bands. It inhabits the deep reefs of the South Pacific, particularly around the Cook Islands. This elusive species is known for its secretive nature and preference for depths of 100-120 meters, making it a rare sight in the wild.

Centropyge boylei, commonly known as the Peppermint Angelfish, is native to the Central Pacific Ocean, specifically found around the Cook Islands.

This species inhabits deep coral reef environments, typically at depths ranging from 50 to 120 meters. The water temperature in these regions is generally tropical, ranging from 24 to 28°C (75 to 82°F). The reefs are characterized by clear water with good visibility, which is crucial for the survival of coral species and reef fish.

Centropyge boylei is a part of the reef ecosystem where it plays a role in controlling algae growth on corals, as it primarily feeds on algae, small invertebrates, and detritus. Its small size and vibrant coloration provide camouflage among the corals and crevices of the reef. This angelfish is adapted to deep reef environments where light penetration is lower, and it has evolved to live in the intricate structure of coral formations.
