What Lamarck Angelfish look like
The Lamarck Angelfish (Genicanthus lamarck) exhibits a striking sexual dimorphism, with males showcasing vibrant blue and yellow coloration, while females are predominantly yellow with a subtle blue hue. Adults can reach a maximum size of approximately 8 inches (20 cm) in length. This species possesses elongated dorsal and anal fins, which contribute to its graceful swimming style. The body is laterally compressed, allowing for agile maneuverability among reef structures. A notable feature is the presence of a distinct black stripe that runs diagonally from the snout to the base of the tail, providing camouflage among the corals. Defensive adaptations include the ability to quickly dart into crevices to evade predators, and they possess a robust set of teeth adapted for grazing on algae and small invertebrates.
Behavior & temperament
The Lamarck Angelfish is generally a peaceful species, often found in pairs or small groups within its territory on the reef. They inhabit the mid to upper levels of the water column and are known for their social hierarchy, with dominant individuals displaying more vibrant coloration. Breeding behavior involves elaborate courtship displays, where males will perform a series of swimming patterns to attract females. They exhibit a degree of territoriality, especially during spawning, but are not overly aggressive towards other species. Their temperament is typically calm, making them suitable for community tanks.
Diet & feeding
In the wild, the Lamarck Angelfish primarily feeds on a diet of algae, small invertebrates, and zooplankton. In captivity, they require a varied diet that includes high-quality marine flakes, pellets, and frozen foods enriched with spirulina and other algae.
Behind the name
The genus name 'Genicanthus' is derived from the Greek words 'genos' meaning 'kind' or 'type' and 'akanthos' meaning 'thorn', referring to the spiny fins of the fish. The species name 'lamarck' honors the French naturalist Jean-Baptiste Lamarck.
