The French Angelfish or Pomacanthus paru is a saltwater fish from the family Pomacanthidae. This species of Angelfish inhabits the western Atlantic from Florida and the Bahamas to Brazil. It is also found in the Gulf of Mexico and the Caribbean.
French Angelfish are most often seen in depths of between 2 and 100 m and can grow up to 16" (41 cm). This species is monogamous, staying with the same partner and defending its territory together against other couples. They are often caught around reefs and are considered to be quite tasty.
When these fish are young they act as cleaner fish, removing parasites and other "food" from the bodies of other fish including jacks, snappers, morays, grunts, tangs, and wrasses. The fish that wants to be cleaned does a dance of sorts to let the French Angelfish know they would like to be serviced. You can check out a Tang fish getting cleaned by a juvenile French Angelfish in the video below.
