Origin
Endemic to the central Pacific Ocean, particularly Hawaiian reefs and Johnston Atoll.

Visual & Functional Appeal
Juveniles display bright orange bodies with deep red chevrons. Adults transition to dark purple or near-black with blue edging. Unique among tangs for this dramatic ontogenetic color change.

Purpose
Feeds primarily on detritus and film algae. Helps control microalgae and maintain substrate cleanliness. Adds a mature, refined contrast to colorful reef tanks.

Importance
Chevron Tangs are one of the few tangs that graze detritus in addition to algae, helping prevent buildup in hard-to-reach reef crevices.

Included Resources
Needs well-established reef tanks with high biological maturity. Rockwork must offer plenty of grazing surfaces and hiding spots. UV sterilization helps with disease prevention.

Best Use Cases
Mature reef tanks, SPS-dominated layouts, and setups with slower, less aggressive tank mates. Ideal as a visual transition from juvenile reef tanks to adult displays.

Conservation Context
Collection from Hawaii is regulated to protect populations. Supporting sustainably sourced or aquacultured alternatives is advised where possible.
