Staghorn Coral

About

Staghorn coral (Acropora cervicornis) is one of the most ecologically important reef-building corals in the Western Atlantic, and its branching silhouette is instantly recognizable to anyone who has spent time around Caribbean reefs. Colonies grow into dense, sprawling thickets of cylindrical branches that fork infrequently, giving individual arms a long, tapered look reminiscent of antlers. The tubular corallites along each branch are relatively small, but the axial corallite at each branch tip stands out noticeably. A useful identification feature. Coloration is typically a muted pale brown or tan, with those distinctive axial tips appearing white against the rest of the colony. In healthy populations, stands can span several meters across, and the species plays a significant structural role on upper to mid reef slopes and in clear-water lagoons. In the aquarium, this coral demands serious commitment. It needs intense lighting and vigorous, consistent water movement to thrive, and it is sensitive enough that it really belongs in a mature, stable reef system managed by an experienced keeper. Feeding and water quality need to be dialed in before attempting this one. For those with the right setup, though, watching a colony extend its branches over time is genuinely rewarding.
