Ultra Large Fat Head, Wall Hammer

Wall Hammer Coral (Ultra Large / Fat Head)

Transform Your Tank with a True Show-Stopping Centerpiece

Looking for a wall hammer that commands the room... The Fat Head Wall Hammer is one of the most sought-after LPS corals in the reef-keeping hobby — and for good reason. Its oversized, inflated hammer heads pack densely along a broad wall-style skeleton, creating a sweeping, fluid curtain of movement that few corals can rival. This ultra large specimen delivers instant impact, the kind of piece experienced collectors recognize the moment they see it.

As this coral settles into your saltwater aquarium, those already impressive heads will continue to extend and multiply, gradually claiming their territory with graceful, rhythmic sweeping motion. Wall Hammers are known for their surprisingly assertive character — they will sting neighboring corals, so give them the space they deserve. Watching a Fat Head Wall Hammer fully open under quality LED or T5 lighting is one of the most rewarding sights in the reef tank hobby.
