Key identification features
- Small, oval angelfish reaching about 10 cm
- Bright orange body marked with narrow, wavy blue horizontal stripes across the front half
- Rear body and tail base shift to a noticeably darker blue-black shade
- Fins edged in blue, matching the body's stripe pattern
- Thin blue ring around the eye
- Compact, deep body typical of pygmy angelfish
Common look-alikes
- Coral Beauty (Centropyge bispinosa): body tends toward a more uniform purple-red tone with less contrast between front and rear, lacking Potter's sharply darker posterior half.
- Flame Angelfish (Centropyge loricula): overall red-orange with bold black vertical bars rather than fine blue horizontal stripes, easily separated by the bar pattern alone.
Where you'll see one
Potter's Angelfish is endemic to the Hawaiian Islands, found on rubble slopes and reef edges at moderate depth, where it stays close to cover and darts into crevices when approached. It is one of the most commonly encountered pygmy angelfish on Hawaiian reefs, often seen weaving through rubble and low coral heads while feeding on algae.
Frequently asked questions
How do I tell Potter's Angelfish from a Coral Beauty?
Check the body contrast: Potter's Angelfish has an orange front half with fine blue stripes that sharply darkens to blue-black toward the tail, while the Coral Beauty shows a more uniformly toned purple-red body without that strong front-to-back contrast.
Where is the best place to look for this species?
Because it is endemic to Hawaii, any orange-and-blue pygmy angelfish with a dark posterior seen on Hawaiian rubble slopes and reef edges is almost certainly Potter's Angelfish.
