Ultra Rainbow Acantho

Transform Your Tank with a Living Kaleidoscope of Color

Looking for a showstopper that earns a second look every time? The Ultra Rainbow Acantho is one of the most visually striking large polyp stony corals available in the hobby today. Its sweeping tentacles shift through a spectrum of greens, blues, purples, and reds that intensify under reef lighting — no two specimens are identical. If you're serious about building a reef tank that commands attention, this is exactly the kind of rare addition you've been searching for.

Acanthophyllia deshayesiana is a solitary, free-living coral that grows into a large, fleshy disc over time — a bold centerpiece that demands its own real estate on the sandbed. It's a rewarding species for aquarists who appreciate corals with personality: watch it swell and extend throughout the day as it settles into your saltwater aquarium. Slower-growing and long-lived, this is an investment piece you'll enjoy for years.
