Alien Mushroom is one of the most eye-catching and accessible soft-corals in the hobby—boasting a neon-green to electric-blue base, accented by metallic flecks and shimmering purple or gold highlights that glow intensely under blue spectrum lighting.  Its thick, textured surface and dome-like shape make it a unique “living UFO” on your rockwork, spreading gently over low-lying substrate or rock ledges. Rated as very hardy and fast-growing, making it ideal for both beginners and advanced reefers looking to add bold, fluorescent contrast to their setups.
