PC Rainbow Acropora (Acropora spp.)
The PC Rainbow Acropora is a highly sought-after SPS coral celebrated for its vibrant multi-colouration and classic branching growth. This particular piece comes from my personal collection, where it has been carefully maintained, established and grown on from a small frag into a healthy, well-developed small colony.
 
Often regarded as a staple in advanced reef aquariums, this variety develops sturdy upright branches with contrasting growth tips and vibrant polyp extension.
 
Colour & Appearance
True to its name, the PC Rainbow showcases a blend of greens, yellows, pinks and oranges, often with bright contrasting polyps. Under strong blue spectrum lighting, its colours intensify dramatically, revealing layered tones and vivid fluorescence that create exceptional visual depth.
 
Placement & Flow Requirements
The PC Rainbow thrives under high-intensity lighting and strong, turbulent water flow.
Position in the upper third of the aquarium for optimal light exposure.
