Transform Your Tank with a Coral That Packs Every Color into One Specimen
Looking for an LPS coral that delivers premium multi-color impact without demanding advanced care? The Rainbow Acanthastrea is a staple of serious reef collections for good reason — its densely packed corallites blend reds, oranges, greens, blues, and purples in combinations that shift and intensify under different lighting spectrums. No two are identical. A Rainbow Acantho is one of those corals that rewards every look you give it.
Acanthos are encrusting LPS corals that spread outward over time, gradually covering rockwork with vibrant color. They're adaptable, hardy, and one of the more beginner-accessible LPS options despite their high-end appearance. Place low to mid-tank, keep flow moderate, and feed weekly for best coloration.
