WYSIWYG Grafted Hammer Coral

Grafted Hammer Coral – Euphyllia ancora – Bi-Colour Masterpiece for Premium Reef Displays

The Grafted Hammer Coral (Euphyllia ancora) stands out as a showpiece coral, boasting a unique bi-colour aesthetic that sets it apart from standard varieties. This specimen showcases a seamless blend of neon green and violet tentacles on the same structure, achieved through natural tissue grafting. The result is a mesmerising mix of colour that shifts with the light, especially under actinic or reef-blue LED lighting.

Known for its branching form and dynamic motion, the Hammer Coral sways elegantly in gentle currents, creating a flowing, natural effect. It thrives in stable reef systems with low to moderate lighting and indirect water flow. Its semi-aggressive nature means it should be given adequate space to prevent contact with nearby corals.

The grafted variety is highly sought after by collectors and experienced aquarists looking to add something rare and visually stunning to their aquarium. Over time, it can be fragged while preserving its multi-colour identity.

FAQs:

Q: What makes this a “grafted” coral?
A: It combines two colour morphs—typically green and purple—into one colony via natural tissue fusion.

Q: Is it suitable for beginner reefers?
A: Best for intermediate to advanced aquarists due to its rarity and specific spacing needs.

Q: Can it be kept near other corals?
A: Yes, with at least 5–10 cm spacing to prevent tissue damage from sweeper tentacles.
