French Angelfishes, Pomacanthus paru
« Database Home Animalia Chordata Actinopterygii Perciformes Pomacanthidae Pomacanthus paru
Description & Behavior
French angelfishes, Pomacanthus paru (Bloch, 1787), are common throughout the Caribbean and are often confused with the closely-related gray angelfishes. Like other angelfishes and butterflyfishes, French angelfish have tall, narrow bodies. Because they are so thin, they can turn quickly and maneuver down into narrow cracks between the corals to hunt their prey and avoid predators. They swim by rowing with their pectoral fins. Their long dorsal, anal, and caudal (tail) fins allow them to turn quickly.
Adult French angelfish reach 41.1 cm in length. Their bodies are covered in black scales except those at front from nape to abdomen, which are rimmed with golden yellow. They have a broad orange-yellow bar at the base of their pectoral fins and have a dorsal filament that is yellow. As they become adults their chins become whitish and the outer part of their iris is yellow; eye narrowly rimmed below with blue.
World Range & Habitat
French angelfishes are common in shallow reefs and are usually found in pairs, often near sea fans and sponges. Juveniles are jet black with circular bright yellow bands and they tend cleaning stations where they service a broad range of clients, including jacks, snappers, morays, grunts, surgeonfishes, and wrasses. At the station the cleaner displays a fluttering swimming and when cleaning it touches the clients with its pelvic fins.
Western Atlantic: Florida, USA and Bahamas to Brazil. Also Gulf of Mexico and Caribbean, including Antilles. Eastern Atlantic: off Ascension Island and St. Paul's Rocks.
Feeding Behavior (Ecology)
Spawning pairs are strongly territorial, with usually both members vigorously defend their areas against neighboring pairs.
They are nest nonguarders, reproduce via external fertilization and are open water/substratum egg scatterers.
Conservation Status & Comments
There are reports of ciguatera poisoning from eating French angelfishes. They have been reared in captivity. The juveniles are frequently taken by aquarists. Easily approached and photographed.

Help Protect and Restore Ocean Life
Help us protect and restore marine life by supporting our various online community-centered marine conservation projects that are effectively sharing the wonders of the ocean with millions each year around the world, raising a balanced awareness of the increasingly troubling and often very complex marine conservation issues that affect marine life and ourselves directly, providing support to marine conservation groups on the frontlines that are making real differences today, and the scientists, teachers and students involved in the marine life sciences.
With your support, most marine life and their ocean habitats can be protected, if not restored to their former natural levels of biodiversity. We sincerely thank our thousands of members, donors and sponsors, who have decided to get involved and support the MarineBio Conservation Society.
