Burgess's Butterflyfish

Snapshot: Despite its modest size, this fish commands attention with its striking black and white palette. It sports three distinct black bands — the first creates a dramatic mask over its eyes, the last swathes the majority of its back.
 
Other tidbits: Can grow up to 12cm or so. Native to the deep tropical waters of the Indo-Pacific region including Indonesia, the Philippines and Palau.
 
Bare bones must know: Best suited to a live-rock fish only system. Top-notch water quality.
