Bristletooth Tomini Tang

Snapshot: As a juvenile, it's a tan canvas splashed with yellow, blue, and white. As it matures, it body colour solidifies with a blue tail, and dorsal and anal fins dipped in gold. Golden flecks dance above the eyes, while a gleaming half-circle adorns its underside. 
 
Other tidbits: Can grow up to 13cm or so. Native to tropical waters of the Western and Central Pacific Ocean from Indonesia to the Solomons and Palau. 
 
Bare bones must know: Live-rock fish only system, or reef aquarium. Top-notch water quality.
