Origin
Native to reef slopes and lagoons of the central Pacific, especially around the Hawaiian Islands and nearby atolls.

Visual & Functional Appeal
Intensely yellow body with subtle white spines at the tail base. Graceful, streamlined swimmer that contrasts well with coral and live rock. Active during the day and constantly grazing.

Purpose
Functions as both a showpiece and an algae controller. Its movement adds energy and rhythm to reef tanks while contributing to cleanliness.

Importance
A long-standing reef favorite for its hardiness, utility, and beauty. Easily recognized even by non-aquarists, it bridges aesthetics with ecological function in community reef tanks.

Included Resources
Requires strong biological filtration, moderate to high flow, and mature live rock with algal surfaces. UV sterilization and quarantine recommended.

Best Use Cases
Reef aquariums with ample swim space. Pairs well with most coral species. Avoid with other tangs unless in very large tanks.

Conservation Context
Now aquacultured by facilities like Oceanic Institute, reducing wild harvesting. Trade regulations have helped stabilize populations.
