Rainbow HG 3 BIG HEADS COLONY

Rainbow HG Hammer Coral — 3-Head Colony

Transform Your Tank with a Rare, Color-Saturated Showpiece

Looking for a centerpiece coral that stops you mid-glance... The Rainbow HG (High Grade) Hammer Coral is one of the most sought-after Euphyllia variants in the hobby — and a 3-head colony means you're getting real, established growth, not a single frag you'll be nursing for years. The signature multi-toned tips shift between gold, pink, green, and purple depending on your lighting spectrum, creating an almost surreal display that no two tanks will replicate identically.

Three well-developed heads give this colony an immediate visual presence, filling negative space with its characteristic flowing, hammer-shaped tentacles that sway with tank flow in a way that draws the eye on every pass. As it settles and thrives, it will continue to develop new heads, compounding your investment over time. Hammer corals are also known for their bold, animated character — an active sweeper that adds life and dimension to any reef tank arrangement.
