Spanish Hogfish

Snapshot: The Spanish Hogfish rocks a golden-yellow body with a wicked blue streak across its back.
 
Other tidbits: Can grow up to 40cm or so. Distributed throughout the Mexican Golf, and the West Atlantic Ocean. It’s the ultimate underwater cleaner, zipping around and scrubbing parasites off its tank buddies. These fish are stealthy little hunters, on the prowl for crustaceans, sea urchins, and worms.
 
Bare bones must know: Live-rock fish-only system, or reef aquarium with care. Larger sized aquarium needed when fully grown.
