Cortez Angelfish

Snapshot: As youngsters, these fish impress in sleek black with bold yellow and blue stripes that run from mouth to tail. But as they mature, they mellow out, trading in the flashy look for a chill brown or gray vibe with just a hint of blue and yellow flair.
 
Other tidbits: Can grow up to a whopping 46cm or so! Cortez Angelfish rock their name straight from their hood, the Sea of Cortez, off Mexico's coast. 
 
Bare bones must know:  Live-rock fish-only system, fish-only system or reef aquarium with care. Larger sized aquarium needed.
