What French Angelfish look like

The French Angelfish (Pomacanthus paru) exhibits a striking coloration characterized by a deep blue to black body adorned with vibrant yellow edges along its scales and fins. Adults can reach a maximum size of approximately 15 inches (38 cm) in length. Sexual dimorphism is subtle, with males typically displaying slightly larger dorsal fins and more pronounced coloration than females. This species possesses a robust, laterally compressed body with a distinctive, elongated dorsal fin that can be raised or lowered, and a prominent, pointed snout. The dentition is specialized for grazing on algae, featuring a set of strong, flat teeth. Additionally, the French Angelfish has a unique lateral line system that aids in detecting vibrations in the water, enhancing its ability to navigate and find food in its reef habitat.

Behavior & temperament

French Angelfish are known for their relatively solitary nature, often establishing a defined territory within the reef environment. They typically inhabit the mid to lower levels of the reef and exhibit a moderate level of aggression, particularly towards conspecifics and other similar-sized fish. During breeding, they engage in elaborate courtship displays, which include synchronized swimming and the establishment of nesting sites on rock surfaces. Their behavior is characterized by a combination of grazing and hovering, as they meticulously search for algae and small invertebrates. French Angelfish are also known to form loose pairs during mating seasons, showcasing a degree of social interaction that is less common among other angelfish species.

Diet & feeding

In the wild, the French Angelfish primarily feeds on a diet of algae, sponges, and small invertebrates, making it an omnivorous grazer. In captivity, they thrive on a varied diet that includes high-quality marine pellets, spirulina, and fresh vegetables.

Behind the name

The genus name 'Pomacanthus' is derived from the Greek words 'poma' meaning 'cover' and 'akantha' meaning 'thorn', referring to the spiny dorsal fin. The species name 'paru' is derived from the indigenous Tupi-Guarani language, meaning 'to be beautiful'.
