Description

The Staghorn Damselfish (Amblyglyphidodon curacao), also known as the Clouded Damselfish or Black-snouted Sergeant Major, is a small, tropical reef-associated fish easily recognized by its pale silvery-green or white body and vertical bars. They are often seen in small groups hovering over staghorn coral (Acropora).

Behavior

The Staghorn Damselfish (Amblyglyphidodon curacao) is an active, generally peaceful planktivore often found in small groups hovering over branching Acropora coral in lagoons, notes. They are hardy reef inhabitants that primarily forage in the water column but can exhibit territorial behavior towards similar species when establishing territory

Reproduction

Staghorn damselfish (Amblyglyphidodon curacao) are oviparous, multiple-spawning fish that breed during summer months, typically laying eggs on dead Acropora coral branches. Males maintain these benthic nest sites, guarding and aerating the demersal eggs, which are often deposited by multiple females

Communication & Perception

Staghorn damselfish (genus Dascyllus and similar reef-dwelling Pomacentridae) use a complex, multi-modal communication system blending acoustic signals, visual patterns, and UV perception to navigate social hierarchies, mating, and territory defense

Predator

groupers, snappers, lionfish, and triggerfish
