Snapshot: A true warrior, boasting a tan hue with bold dark lines. Catch the brilliant blue circling its scapulae and anal fin outline. 
 
Other tidbits: Can grow up to 31cm or so. Native to the tropical waters of the Indo-Pacific region including Malaysia, Thailand, and Indonesia.
 
Bare bones must know: Live-rock fish-only system, or reef aquarium with plenty of live rock and swimming room. Larger size aquarium needed.
