'angelfish' originates from English, combining 'angel' and 'fish', where 'angel' refers to the graceful or beautiful appearance and 'fish' refers to the aquatic animal.

'Angelfish' was formed in English by combining 'angel' and 'fish' to describe certain species of fish with elegant shapes or markings.

Initially, it referred to any fish with an angelic or graceful appearance, but now it specifically refers to certain species in the family Pomacanthidae (marine) or Pterophyllum (freshwater).
