Rainbow Symphyllia

Rainbow Symphyllia

Transform Your Tank with Living Art in Motion

Looking for a showstopping centerpiece coral... The Rainbow Symphyllia is one of the most visually arresting large polyp stony corals in the hobby, displaying sweeping valleys of electric color — greens, blues, pinks, and purples — that shift under reef lighting in ways that photographs simply can't do justice. Rarer than the standard brain coral and far more dramatic in coloration, this is a specimen that draws eyes the moment it hits the rockwork. At The Coral Boutique, we select only the most vivid, well-structured pieces available.

Symphyllia corals grow in broad, domed colonies with deep fleshy valleys that expand beautifully at night, giving your reef tank a sense of organic movement and depth. They're a rewarding choice for intermediate reef keepers — hardy enough to forgive minor parameter swings, yet responsive enough to show you exactly when your system is dialed in. Place them on the sandbed or on low rockwork with moderate flow, and watch them settle into their permanent role as the anchor of your aquascape.
