Yellowbar Angelfish

Snapshot: Also known as the Yellow-band Angelfish, Map Angelfish, or Blue Moon Angelfish. Juveniles are deep blue with crisp white bars and a metallic glow. As they grow, the stripes fade, neon blue patterns pop, and a bold yellow bar takes center stage. Fully grown, they’re stunning blue with a big mid-body yellow splash and a translucent yellow tail (unlike the Asfur’s solid yellow tail and dark purple vibe).
 
Other tidbits: Can grow up to a whopping 50cm or so! Distributed throughout the East Indian Ocean, West Indian Ocean, and The Red Sea. 
 
Bare bones must know: Live-rock fish-only system. Top-notch water quality. Larger size aquarium needed.
