Angelfish are among the most colorful reef fish, easily recognized by their laterally compressed bodies and striking patterns. Their colors range from bright yellows and blues to intricate stripes and spots, making them favorites for underwater photography. Juveniles often look quite different from adults, with bold color contrasts that gradually change as they mature. These fish can grow up to 60 cm, although most species divers encounter are smaller.
Angelfish are diurnal, spending daylight hours grazing on algae, sponges, and small invertebrates. Many species form monogamous pairs, while others may be seen in small groups. They are territorial, especially during breeding season, and use their bold colors both for camouflage and communication.
Divers will often see angelfish gliding gracefully along reef walls or darting into coral crevices. Patience is rewarded, as these fish often return quickly after darting away. Their vibrant colors make them a joy to photograph, though care should be taken not to disturb them in tight reef structures.
Most species are listed as Least Concern, though some face pressures from habitat degradation and the aquarium trade.
