Asfur Angelfish

Snapshot: Rocking a bold palette of dark blue and deep purple, it's body is contrasted by a striking black face and vibrant yellow tail. A standout yellow crescent slices vertically through its body, adding an extra pop of color. 
 
Other tidbits: Can grow up to a whopping 40cm or so! Range extends throughout the Persian Gulf and the Red Sea.
 
Bare bones must know: Live-rock fish-only system. Larger size aquarium needed.
