Hawaii Reef Fish Guide
Angelfishes
Angelfishes bring bright color to Hawaii's shallow reefs, often gliding close to coral and rocky ledges. They look a lot like butterflyfishes at first, but angelfishes have a small spine on the gill cover that helps set them apart.
Angelfishes on Hawaii Reefs
Angelfishes are colorful reef fish that live around Hawaii's shallow coral reefs, rocky ledges and reef walls. They are part of the Pomacanthidae family, with about 86 species found worldwide. About five species are commonly seen in Hawaiian waters.
For snorkelers and divers, angelfishes are fun to spot because they move close to the reef and often show bright colors or bold markings. Some may have yellow, blue, orange, black or white patterns. Their flattened bodies help them slip around coral heads, reef cracks and sheltered areas where they can feed and hide.
How to Recognize Angelfishes
Angelfishes can look similar to butterflyfishes, especially when you only get a quick look underwater. Both groups can have flat, colorful bodies and often swim near coral. One helpful difference is that angelfishes have a small spine on the gill cover, called the operculum. Butterflyfishes do not have this feature.
Angelfishes may also look a little heavier-bodied than many butterflyfishes. They often stay close to reef structure, where they feed on algae, sponges, small invertebrates and other reef foods depending on the species.
When watching angelfishes in Hawaii, move slowly and give the reef plenty of space. Avoid touching coral, chasing fish or stirring up sand. Calm, patient snorkeling usually gives you the best view. Related pages include the Hawaii fish guide, Hawaii snorkeling, wrasses and damselfishes.
