WYSIWYG Grafted Hammer Coral

Grafted Hammer Coral – Euphyllia ancora – Rare Fusion of Colour and Form for Reef Aquariums

The Grafted Hammer Coral (Euphyllia ancora) represents one of the most visually captivating LPS corals available. This extraordinary specimen displays two distinct colour morphs—typically deep violet and neon green—grafted seamlessly into a single structure. Each tentacle branch showcases a unique expression, creating a coral that appears hand-painted by nature.

This branching hammer coral thrives under low to moderate lighting, with fluorescence intensifying under blue or actinic LEDs. Gentle to moderate indirect flow supports healthy polyp expansion and maintains its smooth, flowing movement, which adds life and texture to any reef aquascape.

As a semi-aggressive species, it must be placed with care to avoid contact with other corals. The Grafted Hammer Coral is well-suited for aquarists looking to add a centrepiece coral that is both rare and manageable, with propagation potential over time.
