Elegance corals from Australia and do well in reef aquariums. They are beautiful pieces, large and full of motion, especially this specimen which inflates very nicely and has long tentacles with pink/purple tips!
First described by William Saville-Kent in 1893, the Catalaphyllia jardinei, known as the Elegance coral (also called the Wonder coral), is a member of the Euphylliidae family. Elegance corals are large polyp stony (LPS) corals. I believe the Elegance coral inspires "love at first sight" with a lot of Reef Chasers. Elegance corals are typically a shade of fluorescent green with green or contrasting tentacles of tan or white, often ending in pale pink, blue, or lavender tips. Elegance colonies can grow up to 12 inches in length and 8 inches in width. Their tentacles can extend an additional 4 inches in all directions.
