The Cristata Torch Coral (Euphyllia cristata) is a beautiful LPS coral with short, rounded tentacles. Colors vary widely ranging from yellow, red, purple, and green. There should always be plenty of space between the Torch Coral and other corals or inverts as it can have potent stings. They thrive best with moderate lighting and moderate waterflow. The Torch Coral is popular, and for good reason as it is incredibly beautiful.
