Biology and life history (FishBase)

Measured values published by FishBase for Pomacanthus paru. Only fields the database actually holds for this species are shown; these are database values, not aquarium guidance.

Maximum length: 41.099998474121094 cm · Common length: 28 cm · Depth range: 3–100 m · Habitat zone: reef-associated · Body shape: short and / or deep · Vulnerability index: 38.5 of 100 · Fishery importance: minor commercial · Aquarium trade: commercial.

FishBase notes: Common in shallow reefs. Usually in pairs, often near sea fans (Ref. 9710). Feed on sponges, algae, bryozoans, zoantharians, gorgonians and tunicates (Ref. 9626).

Oviparous (Ref. 240), monogamous (Ref. 52884). Spawning pairs are strongly territorial, with usually both members vigorously defending their areas against neighboring pairs (Ref. 38726). Juveniles 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 (Ref. 40094). Flesh considered good quality; marketed fresh (Ref. 3797). Has been reared in captivity (Ref. 35419).

Description and natural history (Wikipedia)

The French angelfish was first formally described as Chaetodon paru by the German physician and naturalist Marcus Elieser Bloch (1723–1799) with the type locality given as Brazil and Jamaica. The species is placed by some authorities in the subgenus Pomacanthus,. The specific name of this species, paru is the Portuguese name for this species.

Description

The French angelfish has a deep but vertically compressed body, making it appear flattened from the front. The head is deep, with a short snout that ends in a small mouth containing numerous bristle-like teeth. There is an obvious spine at the corner of the preoperculum while there are no spines on the operculum or under the eye.

The dorsal fin contains 10 spines and 29–31 soft rays while the anal fin contains 3 spines and 22–24 soft rays. This species attains a maximum total length of 41.1 cm. Males grow to around 18in (45cm), while females reach a slightly smaller size.

Both males and females have a black or dark gray body that contrasts with the bright yellow tips of their scales on most of their body. They have a white mouth and a yellow orbit.

The pectoral fins have a wide orange-yellow band and the dorsal fin has a long yellow filamentous extension growing from its soft-rayed part. Juvenile French angelfish have different markings from adults. Juveniles are almost completely black apart from five vertical yellow bands, that run down the entire height of their body, the first around the mouth and the last at the caudal peduncle.

Distribution

French angelfish can be found in the western Atlantic from Florida to the Gulf of Mexico and down towards Brazil and the Caribbean, including the Antilles, Roatan, and the eastern Atlantic from around Ascension Island and St. Paul's Rocks.

These fish can be seen in water depths above about 15ft, or about 4.5m, and they have also been reported at depths within the mesophotic zone, which is between 30m and 150m, or about 100ft - 500ft.

Feeding

French angelfish live in and around coral reefs and rocky shores. As adults, these fish primarily feed on sponges with around 70% of their diet consisting of sponges.

The comb-like teeth of adults help to grind up pieces of sponges. In contrast, juvenile French angelfish feed by consuming ectoparasites on larger fishes. As a result, juveniles spend a huge portion of their time at or near their cleaning stations.

As juvenile French angelfish grow in size, they become more generalist when it comes to species of sponge they eat, eating around twelve to fifteen sponge species, which is similar to their adult diet. This shows there is a direct relationship between the size of the juvenile and how much sponges contribute to their diet, with large juveniles eating more sponges than smaller juveniles.

Juvenile cleaning stations

Like juveniles of some other angelfish species, juvenile French angelfish are well documented cleaner fish; many larger fish species allow or implore them to approach to feed on ectoparasites, mucus, dead tissue, and other undesirable particles.

In the Caribbean, certain patches of the ocean floor may be used by young green sea turtles as "cleaning stations". At such cleaning stations, multiple species of cleaner fish of varying families coexist and provide cleaning services to the turtles as well other fish that seek cleaning services. At these stations, juvenile P. paru primarily clean the sea turtles' heads, carapace, and plastron.

French angelfish are common on rocky and coral reefs where it is normally encountered in pairs, frequently in the vicinity of sea fans. Its diet comprises sponges, algae, bryozoans, zoantharians, gorgonians, hydroids, coral and tunicates. These pairs are highly territorial, and typically both vigorously defending their territory from their neighbours. Juveniles act as cleaner fish and establish cleaning stations.

Species recorded as being clients of juvenile French angelfish, include jacks, snappers, morays, grunts, surgeonfishes and wrasses. These fish are active during the daylight hours, but seek shelter in their designated hiding spot where they return every night. They can produce a knocking sound when alarmed.

In many fish species, the age of an individual can be estimated by analyzing its otoliths. In French angelfish, an opaque band forms on the sagittae otolith with every year of growth. A 2016 study of French angelfish otoliths found that the oldest specimen in the study was 27 years old.

In a captive specimen in Georgia, researchers found endoparasites (parasites that live within the host body) of the genus Enterogyrus on its foregut wall. The way in which these parasites attach themselves to their host was unusual, as the parasites attached themselves perpendicularly to the folds in the foregut.

In French angelfish, there are no obvious courtship displays or clear sexual dimorphism between the sexes. The species forms monogamous pairs, unlike its closest relative, the grey angelfish, which mates in polygamous groups.
