Common look-alikes
- Emperor Angelfish (adult): also striped, but bands run horizontally in blue and yellow rather than diagonally in blue and orange, and lacks the Regal's orange face
- Vermiculated Angelfish: shows a maze-like blue pattern over a dark body rather than the Regal's clean alternating diagonal bands
- Six-banded Angelfish: has a comparable banded look but the bands are wider, fewer in number, and run over a paler background than the Regal's fine diagonal stripes
Where you'll see one
Regal Angelfish inhabit clear coral-rich reefs across the Indo-Pacific, from the Red Sea to French Polynesia, generally at depths of 3-50 feet, often sheltering in caves or under ledges on outer reef slopes.
