Elkhorn Coral
Acropora palmata
A Caribbean reef giant with thick, branching arms built to take a pounding.

About
Elkhorn coral (Acropora palmata) is one of the most architecturally impressive corals in the Western Atlantic, forming massive colonies that can stretch over four meters wide and stand nearly two meters tall. The thick, tapered branches flatten toward their tips in a way that genuinely does recall the antlers of an elk, and the whole structure takes on a pale tan to light brown coloration with whitish corallite openings scattered across the surface. In the wild, this species dominates shallow outer reef slopes where wave energy is constant and intense. It is essentially engineered for turbulent, well-oxygenated water. That natural habitat tells you a lot about what it needs in captivity: very strong flow and extremely high lighting are non-negotiable, and even then, replicating the conditions this coral thrives under is genuinely difficult. It is considered an advanced coral to keep, and that reputation is well earned. Beyond the husbandry challenge, A. palmata is an ecologically significant species that has suffered serious declines across its Caribbean range, so any captive specimens are best sourced responsibly. This is a coral for dedicated, experienced reefers with appropriately scaled systems.
