Large Rainbow Acantho
Transform Your Tank with One of the Most Color-Packed LPS Corals in the Hobby
Looking for an LPS coral that genuinely earns the word "rainbow"? The Acanthastrea (Acantho) is beloved in the reef community for its rich, multi-toned coloration — and a rainbow morph takes that to the extreme, layering reds, oranges, greens, purples, and blues across its fleshy corallites. This large specimen gives you substantial coverage and maximum visual impact. These are the corals that make visitors to your home ask, "what is that?"
Acanthos are encrusting LPS corals that grow outward over rockwork and substrate, making them ideal for mid-to-low placement in the tank. They're hardy, adaptable, and one of the more forgiving LPS options for reefers who want high-end color without ultra-demanding care requirements.
