With their bright colours and deep, laterally compressed bodies, marine angelfishes are some of the more conspicuous residents of the [[reef]]. They most closely resemble the [[butterflyfish]]es, a related family of similarly showy reef fish. Marine angelfish are distinguished from butterflyfish by the presence of strong [[Operculum (fish)|preopercle]] spines (part of the [[gill]] covers) in the former. This feature also explains the family name Pomacanthidae; from the [[Greek language|Greek]] πομα, ''poma'' meaning "cover" and ακάνθα, ''akantha'' meaning "thorn".

Many species of marine angelfishes have streamer-like extensions of the soft [[dorsal fin|dorsal]] and [[anal fin]]s. The fish have small mouths, relatively large [[pectoral fin]]s, and rounded to lunate tail fins. The largest species, the [[gray angelfish]], ''Pomacanthus arcuatus'', may reach a length of {{convert|60|cm|abbr=on}}; at the other extreme, members of the genus ''[[Centropyge]]'' do not exceed {{convert|15|cm|abbr=on}}. A length of {{convert|20|to|30|cm|abbr=on}} is typical for the rest of the family. The smaller species are popular amongst [[Aquarium|aquarist]]s, whereas the largest species are occasionally sought as a food fish; however,  [[ciguatera poisoning]] has been reported as a result of eating marine angelfish.

Angelfish vary in color and are very hardy fish. When kept in aquariums they can easily adapt to pH and hardness changes in water and can handle conditions that are not considered to be perfect. They are usually a long-living species and are easy to care for. They were very expensive in the aquarium trade when first discovered, but have become more popular and therefore less pricey.

The [[queen angelfish]] grows to be {{convert|45|cm|abbr=on}}. With neon blue and yellow scales and [[iridescent]] purple and orange markings, surprisingly it is not conspicuous, and actually hides very well, and is very shy.

As juveniles, some species are different colors than when they reach adulthood. For example, the Blue Angelfish is a vibrant, electric blue color with black and white stripes or spots. When they reach adulthood, they turn a grayish color with yellow and blue fins and dark spots on their bodies.
