Key identification features
- Vivid yellow covers the front half of the body, including the head, front fins, and forward flank
- Black covers the rear half of the body and extends onto the tail, outlined by a thin blue edge that shimmers in bright light
- Blue-ringed eye set against the yellow head
- Rounded dorsal and anal fins, sometimes with a faint blue trim
- Grows to about 20-25 cm, smaller than most other Atlantic angelfish
Common look-alikes
- Juvenile rock beauty is almost entirely bright yellow with just one black spot ringed in blue near the rear body, easily mistaken for an unrelated small yellow fish until the black area expands with age
- Queen angelfish shares yellow and blue coloring but has an overall blue-green body with a blue "crown" spot on the forehead rather than a sharp yellow-black split
Where you'll see one
Found on coral reefs and rocky hard-bottom habitats of the western Atlantic and Caribbean, usually near ledges and crevices at depths of 3-30 m, often sheltering close to cover.
