The Pro Corals (PC) Rainbow Acropora (Acropora sp., a legendary aquacultured strain originating from breeder Sunny of Pro Corals in the mid-2000s) is a timeless classic in the reef aquarium hobby, descended from a single mother colony and prized for its bold, multi-tonal coloration that evokes a true "rainbow" effect—making it a must-have centerpiece for SPS enthusiasts despite its intermediate difficulty.
Structure: Classic staghorn or branching morphology with upright, finger-like branches that radiate in a bushy, fractal pattern, forming dense, vertical colonies from an encrusting base; branches are robust yet elegant, often developing into a red stag form with upturned tips.
Coloration: Features a deep red skeletal base and outer tissue transitioning to vibrant orange inner body and polyps, accented by bright yellow-gold highlights and a subtle blue rim around corallites for high contrast; under actinic or blue-enriched lighting, the colors fluoresce intensely—reds deepen, oranges glow warmly, and yellows pop neon—for an iridescent, jewel-like display that varies with tank conditions.
Size and Growth: Frags typically start at ½-1 inch, with fast growth rates once established, capable of forming 6-8 inch tall colonies in 6-12 months; it's a prolific expander that rewards propagation.
