What Bellus Angelfish look like

The Bellus Angelfish (Genicanthus bellus) exhibits a striking sexual dimorphism, with males showcasing a vibrant coloration of deep blue and yellow, while females are characterized by a more subdued palette of pale yellow and blue. Adults can reach a maximum size of approximately 6 inches (15 cm) in length. Notable morphological features include elongated dorsal and anal fins, which are adorned with delicate filaments, enhancing their graceful swimming style. The species possesses a laterally compressed body, allowing for agile maneuverability among reef structures. The presence of a small, pointed mouth equipped with fine dentition is adapted for grazing on algae and small invertebrates, while the lateral line system is well-developed, aiding in sensory perception within their dynamic environment.

Behavior & temperament

Genicanthus bellus is a social species, often found in small groups within the reef environment, exhibiting a clear social hierarchy, particularly among males. They are typically found in the mid to upper water column, where they engage in a variety of behaviors including courtship displays during breeding. Males will perform elaborate swimming patterns to attract females, showcasing their vibrant colors and fin extensions. The temperament of this species is generally peaceful, although males can exhibit territorial aggression during breeding seasons or when competing for mates. Their behavior is characterized by a degree of shyness, often retreating into crevices when threatened.

Diet & feeding

In the wild, the Bellus Angelfish primarily feeds on a diet of algae, zooplankton, and small invertebrates. In captivity, they require a varied diet that includes high-quality marine flakes, pellets, and frozen foods supplemented with spirulina and other vegetable matter.

Behind the name

The genus name 'Genicanthus' is derived from the Greek words 'genos' meaning 'race' or 'kind' and 'akanthos' meaning 'thorn', referring to the spiny fins of the fish. The species name 'bellus' is Latin for 'beautiful', aptly describing the fish's striking appearance.
