Green / Red Mandarin

Snapshot: These stunners have maze-like patterns of blue, orange, and green / red. Aquarists adore these mandarins for their stunning and unique beauty.
 
Other tidbits: Can grow up to 7cm or so. Native to the tropical waters of the Pacific Ocean, it can be found from the Ryukyu Islands south to Australia. The name "mandarinfish" echoes its vivid hues, akin to the Imperial Chinese mandarin robes.
 
Bare bones must know: Live-rock fish only system, or reef aquarium with plenty of live rock and sand.
