Hammer coral (Euphyllia ancora / Euphyllia paraancora) is a hardy LPS coral named for its distinctive hammer- or anchor-shaped tentacle tips that sway gracefully in the current. Found in a wide range of colors—greens, golds, oranges, and multi-color morphs—it adds both movement and texture to reef tanks. Hammer corals thrive in moderate light and flow, need space to avoid stinging nearby corals with their sweeper tentacles, and respond well to occasional target feeding for faster growth.
